Climate change may change the way ocean waves impact 50% of the world’s coastlines
Authors Mark Hemer, Ian Young, Joao Morim Nascimento, Nobuhito Mori
The rise in sea levels is not the only way climate change will affect the coasts. Our research, published today in Nature, found a warming planet will also alter ocean waves along more than 50% of the world’s coastlines.
If the climate warms by more than 2℃ beyond pre-industrial levels, southern Australia is likely to see longer, more southerly waves that could alter the stability of the coastline.
Scientists look at the way waves have shaped our coasts – forming beaches, spits, lagoons and sea caves – to work out how the coast looked in the past. This is our guide to understanding past sea levels.
But often this research assumes that while sea levels might change, wave conditions have stayed the same. This same assumption is used when considering how climate change will influence future coastlines – future sea-level rise is considered, but the effect of future change on waves, which shape the coastline, is overlooked.
Changing waves
Waves are generated by surface winds. Our changing climate will drive changes in wind patterns around the globe (and in turn alter rain patterns, for example by changing El Niño and La Niña patterns). Similarly, these changes in winds will alter global ocean wave conditions.
Further to these “weather-driven” changes in waves, sea level rise can change how waves travel from deep to shallow water, as can other changes in coastal depths, such as affected reef systems.
Recent research analysed 33 years of wind and wave records from satellite measurements, and found average wind speeds have risen by 1.5 metres per second, and wave heights are up by 30cm – an 8% and 5% increase, respectively, over this relatively short historical record.
These changes were most pronounced in the Southern Ocean, which is important as waves generated in the Southern Ocean travel into all ocean basins as long swells, as far north as the latitude of San Francisco.
Sea level rise is only half the story
Given these historical changes in ocean wave conditions, we were interested in how projected future changes in atmospheric circulation, in a warmer climate, would alter wave conditions around the world.
As part of the Coordinated Ocean Wave Climate Project, ten research organisations combined to look at a range of different global wave models in a variety of future climate scenarios, to determine how waves might change in the future.
While we identified some differences between different studies, we found if the 2℃ Paris agreement target is kept, changes in wave patterns are likely to stay inside natural climate variability.
However in a business-as-usual climate, where warming continues in line with current trends, the models agreed we’re likely to see significant changes in wave conditions along 50% of the world’s coasts. These changes varied by region.
Less than 5% of the global coastline is at risk of seeing increasing wave heights. These include the southern coasts of Australia, and segments of the Pacific coast of South and Central America.
On the other hand decreases in wave heights, forecast for about 15% of the world’s coasts, can also alter coastal systems.
But describing waves by height only is the equivalent of describing an orchestra simply by the volume at which it plays.
Some areas will see the height of waves remain the same, but their length or frequency change. This can result in more force exerted on the coast (or coastal infrastructure), perhaps seeing waves run further up a beach and increasing wave-driven flooding.
Similarly, waves travelling from a slightly altered direction (suggested to occur over 20% of global coasts) can change how much sand they shunt along the coast – important considerations for how the coast might respond. Infrastructure built on the coast, or offshore, is sensitive to these many characteristics of waves.
While each of these wave characteristics is important on its own, our research identified that about 40% of the world’s coastlines are likely to see changes in wave height, period and direction happening simultaneously.
While some readers may see intense waves offering some benefit to their next surf holiday, there are much greater implications for our coastal and offshore environments. Flooding from rising sea levels could cost US$14 trillion worldwide annually by 2100 if we miss the target of 2℃ warming.
How coastlines respond to future climate change will be a response to a complex interplay of many processes, many of which respond to variable and changing climate. To focus on sea level rise alone, and overlooking the role waves play in shaping our coasts, is a simplification which has great potential to be costly.

So.......more frequent, long period South swells? What would have to change to cause this?
I'm really trying to find some useful information in this article.
it's kind of scienc-y but says nothing specific.
is there a table you can look up?
Its been condensed for a lay audience who wouldn't ask too many questions, they've done the same with todays Herald article which is taken from the same paper. The idea is that those who want to know more have to buy the paper from Nature.
this one has some raw numbers in it FR
http://www.astronomy.com/news/2013/06/the-fast-winds-of-venus-are-gettin...
"Longer,more Southerly waves" do they mean "More long-period SouthernHemi swells" or "More swells will be of a more southerly direction". Less than 5% of the worlds coastlines affected? That seems a bit conservative. At a guess I would say 30% of the worlds coasts would be affected in some way if there were More big South swells. But hey I'm no expert.
At a guess I assume they mean longer period swells from a more southerly direction.
more south than southwest? thats good for east coast surfers
Looks like it's time for some more of that favourite pastime that is science bashing, just gonna sit back and enjoy this....
Lol
Not you too ... stop with the Global Warming BS!
A few thousand years ago the sea was about 100m LOWER than it is as the moment and the "beach" was about 30km out to sea from current east coast ... a few thousand years before that the sea was about 40m HIGHER than it is at the moment and the coast was about 10-20km further inland ... and so the cycle has been for a the last few hundred millennia ... the seas gunna come and the seas gunna go .... get over it ....
Put a sock in it, Will.
wow good reply ...
I love it when people cite scientific findings when it suits their argument (or defence of way of life), but dismiss them when they don't...
There's a difference between a comet liquifying the 3 mile thick Laurentide Ice Sheet and the human contribution to global sea level rise. One is preventable/reversible.
Well if temperatures rise by 2 degrees, i think surfing will be the last thing you will be doing...surviving will be the first.
temps rising 2degrees will do stuff all..just imagine, instead of 19 today, it would be 21..20 tomorrow,22 instead..mainstream media hysteria set-up to coerce the masses into spending billions of dollars for what?..
its a cycle..the sooner the so called 'educated' realise their time on earth is finite the more they realise nothing can actually stop it..get a grip or alternatively vote for steggall.
Platinum level trolling.
Platinum level idiocy more like. He doesn’t even posses a primary school level understanding of basic science
not at all daisy, you just need to realise and comprehend that this has been happening for thousands, millions of years..unless you dont believe the science..question..if we were to stop all polution today and the earth still continues to heat, change, melt, rise whatever..what does the science say then? because in all likelihood it actually will continue..history is littered with adaptation, forever evolving..glaciers have melted before then refrozen, sea levels were so high none of us couldve lived where we do now so what caused all the change?.. suddenly we are in an emergency situation? c'mon mate..look at who is controlling the climate research..who funds it....once you start digging it all starts to appear
I liked you better ten minutes ago.
I think the standard of "bongsalot's" contribution to the climate debate may be somehow related to their moniker...
Daisy duke, This is easily one of the better comebacks I’ve ever heard.
Gold!!!
Not convinced myself.
sorry for my rant but..in other news headlines BOM have just said we MAY have a 50% chance of finding a rare simba ooshie today
one thing that's new now crew- humanity has become aware it is self aware- so to sit by and do nothing while it knows it can be a responsible steward for planetary change, is negligence. self aware species become the local version of the creative force in that they then understand that lifes mission to keep on keeping on does not come from a mythological or religious conception of the prime creator. the prime creator is us being human and it does not want to see planet earth and humanity get annihilated by it's own victimhood/ignorance/arrogance. yes life will keep evolving but we have a chance now to assist it in an empowering way for all earth creatures. to do nothing is like sitting and watching your house burn down from your own dropped match because you believe that fire/volcanoes shaped our earth, so that's just the way it is. wake up you mob, this is a wonderful opportunity to leave a legacy worthy of our divine heritage.
A lot of new angles there, maybe some examples...swellnet crew can fix that.

Two different sides of OZ story playing out at opposite ends & both in the firing line.
Did u know that its all happened before and no not even during the last warm period .. Greenland is called GREEN land because it was GREEN with grass not covered in ice... and even as recently as the 1920s you could sail a vessel right through the Arctic: i.e. it melted enough for ships to pass the Bering Straight ...
Need to read some history

Ummm no. "Greenland"was basically a marketing name to attract more Viking settlers.
Outstanding contribution to the discussion by qualified climate scientists Will Smithson, Bongsalot and Bill Boiler. I think Will and Bill are probably the same person, both put a full stop between their first and last names, which seems an odd coincidence.
Cant speak for Bill but the "." is cause you login with Facebook and it puts the "." in so I'm going to assume the Bill logs in with FB as well ...
Sorry adam.12 but your "odd coincidence" is not odd at all and not coincidence but rather just a FB idiosyncrasy ...
bill, bong, will, whoever, it does not matter, it is all about us as we are here right now. u could be like me and know it's a virtual reality, but it really comes down to who we are. mate, imagine if we could do /be something that helped our/future generations.
last breath, u could assist another to be more magnificent than what they currently ari believe u would be 100 %. imagine, our each last breath could help all life on planet earth, would u draw deeply- course u would,
Look its simple:
At best we have about 50 years of oil left and 100 or so years of coal left. If we don't find an alternative energy source its back to the caves for all of us!
And no solar (PV or thermal) and wind will not cut unless we find some miracle battery (unlikely cos we know the chemistry of batteries!) so we need something else .. probably fission then Thorium in the interim and then hopefully fusion ...
So stop wasting our last few precious years and resources on stupid emotional politically driven Green BS (which is what we are doing at the moment) and spend it on good basic science instead because thats the only real solution other than back to basket weaving!
What would actually be wrong with the world being forced to simplify?
Mate, todays' "good, basic science" tells us, or those prepared to believe it, that burning coal like we do now for "100 or so years" won't leave us weaving baskets, we will be well and truly fucked way before then. It isn't politically driven Greens bullshit, the planet doesn't give a fuck about your petty culture wars, and either do I. Go comment on Andrew Bolts blog fucktard, you'll find plenty of like minded numpties over there.
No it doesn't: it tells us nothing of the sort! If it's not obvious I'm one of them .. a scientist ...
The ONLY thing that tells us Armageddon is coming and we should repent is a set of half baked and fudged computer models backed by a politically driven UN that wants to implement some radical form of social justice/change ... that's NOT science that's politics!
PS when u know you have won an argument: name calling, personal insults and usually followed by threats!
Yeah right, you are a scientist. Yeah right, it's all a UN conspiracy.
The scientific evidence is overwhelming yet as a "scientist" you choose to blame Green politics and a "politically driven UN". They are the ones raising global temperatures, melting the ice, raising sea levels.
I stand by my comments and my insults. Now fuck off.
Like I said the only "evidence" that CO2 is the cause of any of the recent warming (if there is such ... the pre satellite/digital T records are very corrupted and the fudge factors in the satellite adjustments are also "interesting" but that's another argument) is the GCM computer models and we know about computer models getting it wrong ... CFCs and Ozone are a classic example: for years we were told (research sponsored by DuPont) that CFCs were causing ozone depletion ... the computer models said so ... well it turns out the computer models were WRONG .. one of the rate constants for one of the free radical reactions (ClO.) was out by a factor of ~10 ... hence the computer models were WRONG: CFCs were not the problem but too late the only viable alternative to CFCs was R134a ... guess who held the patent ??? DuPont ...
Same for Climate Change GCM computer models: garbage in -> garbage out
Follow the money (and in in this case the political agenda as well ...)
More insults ??? Come on I know you have it in you ....
don't forget the insurance companies, they are in on it too, greenie bastards!
As I said below "follow the money ..."
Follow whos' money? Exxons, Chevrons, British Petroleums? How about we follow Glencores money, or Adanis or Clive Palmers? As I said above, just fuck off.
follow the money , follow Exon and its studies on climate change , where Exon knew in the 70's , fossil fuels heated the planet , then Exon created lobby groups to say the opposite of their own research....ah ...
Will you have been conned by the oil lobby....read https://en.wikipedia.org/wiki/ExxonMobil_climate_change_controversy
there are a lot of links but it shows clearly that one of the biggest oil Co's in the world has research that says climate change is real and is being accelerated by man made emissions ........you have been duped
Ok I'll bite ... what kind of scientist are you?
He's a Kelloggs scientist - got his degree in a box of Cornflakes.
‘2 degrees won’t make a difference? ‘ Ignorance at its best.
We have irrefutable evidence to the contrary and if you have missed it you are chosing to do so.
Let’s say the Bill’s, Will’s and Bong’s of the world are right and this is all just part of a ‘cycle’ how could trying to do something about what we’ve fucked up be a bad thing? How could governments who have the technology, means, potential policy to do something about the 1000’s of current and future environmental disasters be a bad thing?
Wouldn’t you think this joint be better with less plastic, more forests, sustainable energy and food sources, healthy ecosystems, etc etc.
The problem with getting it wrong and spending billions on climate change initiatives and alternative energy sources is that if the science is wrong its a shit load of money that could of gone to solving world hunger, education or healthcare.
I'm not saying the science is wrong, but constantly testing it leads to better outcomes.
Be nice if it worked that way, wouldn't it?
But world hunger has been an ongoing issue, around far longer than climate change, so it's not like govts are rushing to put money there, and education and healthcare are constantly under funding threats. If money is saved somewhere it goes into tax cuts, not into the sectors that need it. It's the Australian way.
Geez you always this cynical so early in the morning Stu? U might need to rethink posting before 7am ; )
My point is that these initiatives have an opportunity cost and with the amount of money involved that they actually need to deliver some kind of benefit.
I see your point re: pouring all that money into the sustainability / climate change sector however I don't really see this as mutually exclusive to things such as health and world hunger.
All of this is inter-related. If we fuck up our planet and things go they way they are than how are we going to feed the world's population anyway? If we pollute the waterways or spoil all our fresh water sources what are people going to drink? ........it feels like health, education, etc are all relative to the kind of planet we live on.
My points are have not been so dooms day but more why the hell do we want to live on such a shit hole devoid of nature and healthy enviroments? (or more to the point why would we want this for others - i.e. future gen)
Fair play!
solitude, do u have this fully with what u state? may u do brutha. in my expereience, there is a gut feeling that leads me to a place of how i can assist this planet earth and it's friends., gut feeling, , intuition, whatever it is, i choose to help and assist even though they think i am an idiot, but the feeling og loving to me is 100% better than feeling unloved,
Not quite sure I understand you original question Dave?
Do you mean do I feel I/we can make a difference to the world around us?
The Aliens caused everything. The sooner we start wearing aluminium hats the better. My garden gnome told me the other day.
It’s as if I was floating on a dream filled with giant beans.
All we can really do is exist in the present moment. Mindfulness is a grounding gravity
Why is bill.boilers profile pic from the metal fabrication service page of the indiamart web site https://www.indiamart.com/proddetail/metal-fabrication-service-209437882... .
If it’s written down it’s the truth. Bugger climate change how’s the government trying to stop cashies. Please tax me more.
sorry solitude, i was asking you how you think we can assist the change we seek? i like your understanding of things and I believe we achieve little by arguing with those that obviously don't fully comprehend our responsibility to change our unsustainable and polluting ways. why can't we grow hemp to replace plastics etc etc? What other things do you believe we should prioritize personally? Sorry for the confusing post- i was using alcohol to finally get a decent night's sleep.Thank Christ i did as i was getting pretty buggered.
Hey Dave,
Mate I guess the more I read and see the more I tend to get frustrated. I feel THE only reason change is not swift and absolute is pure GREED. Personal, national and international.
I think with all of the big issues our world has faced education has been the key in the past (e.g. a good example of this would be health issues such as HIV, cholera, deaths from car accidents, smoking etc).
It would seem though there are large parts of the world that aren't educated to what we are doing and the ones that are don't have government support to create the change we need.
From a smaller or more local standpoint there's heaps we can do (and by no means am I the expert)
- eating less meat
- using less / recycling soft and hard plastics
- owning only one vehicle or using public transport
- riding to the beach, surfing local, less OS surf trips
- look through your house and realize how much shit you've got and minimalise
- Downsize
- Support local everything (less freight, air freight has a MASSIVE carbon footprint)
Obviously not an exhaustive list but I feel doing some of the above things not only helps the world we live in but can also help ground yourself. I've got a bunch of little ones and am more and more conscious of the world the past few generations have created for them.
Totally agree Solitude, except going vegan is really the biggest single impact one can have and is the least we should be doing to sort out the mess humans have made. Animal agriculture is the single biggest contributor to climate change, deforestation and destruction of natural habitat. People need to stop putting a fleeting satisfaction of their taste buds above everything else.
not for all .
if you live in the city , probably yes.
if you have any access to local food supplies, then no.
Yeah not sure everyone being vegan is the whole answer - no doubt it would help. I haven't considered it (think about vegetarianism and mainly eat that way).
Hard thing too is Palm Oil - the shit is in everything, how do you avoid that stuff?
As mentioned those are just a few things I do (plenny more I haven't mentioned), there are 1000's of other possibilities.
Be interesting to hear others thoughts......
Can someone qualified actually answer my question? HOW & WHY could we expect More long period South swells? I have some ideas but I'm not sure if they could be influenced by climate change.
Think you'd have to read the paper, Ray. Though I assume it may have something to do with poleward expansion of the tropics, which may in turn push the Roaring Forties further south.
OK without reading the paper can take an educated guess: the GCM computer models are really models for how heat is dispersed around the planet so the [simple] theory is more heat produces more wind to disperse said heat. So again without seeing the actual model runs (and no you cant ALL the models except for GISS are secret!) hot air rises ... cooler air moves in ... more southerly winds in the our hemisphere. But its a lot more complicated than that by things like rotational dynamics (wind at the poles moves slower than wind at the equator so if air moves toward the equator from the poles it has to speed up and creates coriolis circulation and then there's drag etc etc etc etc etc etc .. so there is no simple answer ....
What kind of scientist are you Will?
I'm curious as to what kind of scientist too. If a climate scientist, maybe a little dirty not a co-author on a Nature paper?
Addressing climate change is only going to happen with a combined effort from governments around the world, and not wanting to sound too pessimistic here, that ain't gonna happen any time soon. People power just isn't going to get this one over the line, so if it means more long period southerly swells in the interim, then enjoy it while you can. Also maybe a debate about this with our garden gnomes is better than one with like minded abusive numpties!!!
Agree especially when governments are the real enemy.
Just this morning I read in The Guardian that the NSW water minister specifically changed recommendations in favour of rice growers Barwon-Darling basin. It turns out they were issued with class A licences to draw water (lets them take it during drought) and they did which threw the Barwon - Darling into drought 3 YEARS early.
But get this a staggering 86% of water licences are held by 10 irrigators but only 4 rice farmers hold 75% of all the licences in the basin!!
Solution?? Using tax payers money to buy back the licences issued by the minister in error ..... you couldn't make this shit up.
.... so the real battler farmer out there suffering drought for over 3 years now have been reamed by their own LNP politicians
https://www.theguardian.com/australia-news/2019/aug/21/big-irrigators-ta...
So Vico is going to pump?
bring it on !!
Queue the climate change lynch mob talking about this subject every time a big swell appears on the radar- "the swells are rising" can now replace "the poles are melting". Question is how come Al Gore bought a beachfront mansion with the proceeds of all his speeches from tax paying citizens around the world? Nobody seems to want to answer this. Surfers were traditionally the last culture to accept globalist propaganda crap.
First they ignore you,
then they laugh at you,
then they ask you weird questions about an irrelevant person,
then you win.
It's these types of comments.... "Go comment on Andrew Bolts blog fucktard, you'll find plenty of like minded numpties over there." and "I stand by my comments and my insults. Now fuck off." ....that simply lose me every time when it comes to global warming etc.
Be there an argument or not for it, the fact that people must insult others who have a different or alternate opinion to another seems no longer acceptable. Its moronic.
I try to teach my 6 year old at school about social acceptance and appreciating others views even if not the same as her own...and yet....we resort to the same crap we educate our kids not to do.
Its self defeating. You end up playing the man not the ball. Its the same with most minority groups voices....their message may very well be valid..but people are turned off by the way they insist they're voice must be the loudest. People just end up speaking more loudly to void whats now become just an annoying "noise".
Not too sure which side you're arguing for, Spookypt. Few commenters opened their salvos by assuming anyone who believes in climate change is intellectually deficient, or has been brainwashed, or hasn't read enough.
Condescension never makes for good conversation.
Hey Stu, I have an opinion but not necessarily a side.
As you can see from the "" above the name calling (on this occasion) was coming from a CT believer to a CT non believer. Reverse the role is fine, agree to disagree also fine....but calling people fucktards and telling them fuck off purely because they chose to express their point of view does nothing towards gaining support for their point of view. That's all I was saying....
Although I will add that Social Media may very well bring on Armageden well before I crawl out of bed and find my slippers are wet from the ice caps melting.
Carry on....
I'm not trying to convince anyone and I don't care if I lose support from anyone. I abuse these people because I am sick of them wanting to debate and defend the indefensible. My home (planet earth) is being destroyed by ignorance and greed and these "fucktards" come up with shit like "follow the money", "it's all a green/ UN conspiracy" and "Al Gore bought a beachside mansion" and "surfers were traditionally the last culture to accept this globalist propaganda crap". They don't deserve a reasoned approach or debate in my opinion, so I take every opportunity I have to abuse them and always will. I don't really care what they or anybody else thinks. They are free to reciprocate if they wish, they are free to express their opinion, but I'm not debating this shit with these people anymore, it's hammer time as far as I am concerned.
That's because if I started to talk about integro-differential equations, initial and boundary conditions or temporal or spatial resolution and sub grid phenomena you would not have the slightest idea what I am talking about ... (BTW they are the fundamental mathematics upon which the GCM climate models are based) ..
But that's the problem for a lot of people: this has become not a matter of science but a matter of faith i.e. it is a religious belief and cannot be challenged: "repent now or you are all going to die ...." We even have "Messiahs" like Gore or Attenborough or Suzuki who while all good communicators and charismatic none of whom has the slightest idea about climate science .... and yet whose words are the New Gospel of Global Warming
PS adam.12 ... that wasn't for you .. it was for the benefit of others ...
Please do illuminate us on the fundamental flaws in climate modelling ...
Yes, I'd like to be illuminated too. Maybe by way of a rebuttal to Nature about how the 27 climate science experts that authored the paper have it all wrong lol.
Hmm there have been hundreds of papers (maths, physics, chemistry and numerical analysis) on problems with climate models so to do it justice here is impossible; but the short version:
Sub Grid:
1: spatial resolution: the models divide the atmosphere up into BIG cubes .. they are WAY too big .. huge storms which move heat from one place to another are ignored inside these "cubes"
2: temporal resolution: the models divide time into steps but the steps are too big, just as with spatial, massive events which move GigaWatts of energy are ignored in what are called "sub grid phenomena"
There is no way to fix the problem because we do not have computers fast enough or big enough to reduce the space or time steps ..
Maths:
1: We do not know the initial conditions for the IDEs (starting point of Temp,Humidity, Pressure,CO2, N2, CH4 blah blah etc etc, for the equations)
2: We do not know the boundary conditions for the models: i.e. what the parameters are when they fall over
The Theory:
We know (it is provable mathematically) that if we do not have enough resolution or that we do not know the initial/boundary conditions then these types of models DO NOT WORK (it doesn't matter whether its climate, aerodynamics, fluid flow, electrical, engineering .. the maths is all the same ...)
Physics and Chemistry
The models try to emulate real world molecular interactions (heat etc) with MODELS .. they are not real they are just approximations of the real thing .. but with experience we can get them pretty close (planes fly cos we can model air flow etc) .. BUT ONLY FOR SIMPLE things .. the physics and chemistry of the atmosphere and the sun and the solar system and the galaxy (yes we need that too cos gamma rays make clouds!) are just way too complex and we KNOW that the models are MISSING many many things so they are FUDGED in the models like cloud cover is just FUDGED!!!
But the real problem is THEY DON'T WORK .. in reports like the UN IPCC report you only see the the models that they want you to see .. you never see the ones that don't follow the "agenda" ....
EXACTLY the same models are used for day to day weather prediction and while they sort of get it almost right most of the time for a day or so in the future we know they have some serious problems getting it spot on for tomorrow let alone next week ... are we really going to change the very fabric of human society based on our ability to predict the weather a hundred years from now ... ???
That's a layman's intro to modelling the atmosphere
But as a scientist why waste your breath arguing with "laymans", or those that wouldn't know an integral-differential from an inhomogenous Poisson process, when you could be publishing rebuttals in Nature and set for life.... Doesn't make sense to me
Very good question!
As to layman as you can see here: layman don't understand either the mathematical/physical issues or even the political ones but they VOTE and they VOTE based on what they are told in the media ... and the media is dominated by the left viz the ABC/Fairfax in Australia/ BBC/Guardian in the UK/NBC etc in the US. who champion AGW for political not scientific ones. The ONLY dissenting media voice is News
EDIT: ABC budget 1Billion + Fairfax 1.6Billion Vs News 2 Billion ... just in case someone said it ...
And as for Nature .. good luck .. they basically wont publish anything that doesn't follow the [political] agenda .. the same people who sit on the editorial throne of Nature are the very same such as the East Anglia Uni Climate Research Unit scientists who refused to release the worlds RAW [un fudged] historic T data until ordered to do so by a court and then promptly "lost" it all .... There are journals that publish off agenda but they are more specialised and more esoteric such as Journal of Atmospheric Chemistry etc stuff that that doesn't make the mainstream media .. no front page story in "no emergency her folks, please move on ..." Look at the CFC/Ozone farce for example ... most people still believe it was CFCs that caused a problem with Ozone even though it has been utterly proved false since ...
Appreciate you taking the time to provide a detailed answer. The issues with modelling are not unique to climate science; what is unique is the size and complexity of the system they're trying to model.
Yes modelling has flaws but good science should be clear about the assumptions and uncertainties in modelling outcomes.
At the very least a model will show you where your data gaps are and provide you with areas for further research. It seems you're discrediting the science without providing an alternative for changes observed in measurable values.
I'm not a climate scientist and I'm not going to get into a debate about the science with you BUT if you are a climate scientist I find it very odd that you're on this forum arguing with such passion. Surely there are better ways for you to contribute to the science?
Hi Jayet
True: they are a mathematical issue that is common issues to the method of integro differential models to approximate reality and the climate complexity is two fold: scale in time/space and the complexity (we don't even know what we don't know e.g. we dont know how clouds form: there is NO model!!!).
As for uncertainty you may notice they never do Monte Carlo analysis of the GCM models ... well they never publish it if they do ;-)
Models are NOT science: the science is in the understanding of the physics (newtonian and quantum) , chemistry, solar and galactic processes. The models are just maths and numerical analysis techniques to approximate those principles.
I'm a retired scientist and doctor with a special interest in maths so I already knew most of the physics and chemistry fundamentals, downloaded the source for the only publicly available model (NASA), learnt Fortran and studied it for a few years.
But I'm also a surfer and just checked in to see if er are getting any swell this weekend and saw the article ... I've done my bit for 40+ years ... time to surf and ride and see the world :-)
It is scary and dangerous when science becomes less about science and more about politics and money.
You're right about DuPont and wrong about CFCs. They did (and do) cause ozone depletion, however the Montreal Protocol was manipulated to favour some products, and therefore the companies that make them, over others. However the notion that it was a farce and the science was false is self-serving bollocks that's, not coincidentally, getting a revamp by RWNJs who use it as an analogy with AGM.
Surprise, surprise.
I'm glad to see some common sense Will
will you are working from a base that has been completely discredited , called the fossil fuel industry . just lies and bullshit when for example Exxon has known since the 70's that fossil fuels heat up the planet , their own research shows that they have been spreading disinformation topeople like you for decades,,
https://en.wikipedia.org/wiki/ExxonMobil_climate_change_controversy........'s the proof!
Wikipedia the new "Oracle" I'll just ask one question .. OK two:
1: who "creates" wikipedia ?
2: go and try and edit an entry in Wikipedia ... and watch the fun ... haha lol
Sorry Brutus I'm with Will on this one.
Wiki is not a credible source.
Always enjoy listening to you talk about board design and fluid dynamics!!!
Fluid dynamics and surfboards/fins and sea water and turbulence and air resistance and laminar Vs non laminar ..... now there's a hard problem ...
Will, if you start making such assumptions or start insulting my intelligence I'm gonna start abusing you again.
Its arguable the non CT believer would just say you're as ignorant as what you acuse them of. See roundy roundy we go. Nothing achieved..Just wind and energy.
A couple a 1000 + years or so ago man exited his cave with a large piece of timber on his shoulder and since that day has for all reasons known and unknown, been beating the $hit out of each other ever since.
I often wonder if it had of been a woman with boobs and bushwarby snatch whether we'd be in a vastly differently place.
Thirty years of data is about a 1000 years short of data required for model extrapolation
Just more of the same global warming unscientific crap which gets fed out
It's about time someone actually said we don't really have any idea about the climate and where it's headed
Thirty years of data is meagre. Fortunately due to ice core sampling, carbon dating, sediment deposition etc etc etc climate scientists have much more data at hand.
seems like we do though.
and when the observations are fitting the theory/model predictions then I'd need to see a very strong evidence based counter-argument, not just a bunch of right wing talking points spewed back from anonymous internet shit talkers.
did anyone do the bell jar experiment at school? fruitflies or other insects were entrapped in a jar- just like an electromagnetic field that surrounds planet earth, they were fed, encouraged to breed and when they had such a large population that was emitting gas, waste etc they started to die off and the species perished.
so - many humans - emitting pollution- creates imbalance in the planet's ability to support them- they perish- but in our case other species do as well.
the difference is we understand this so we the opportunity to create a different outcome if we start to do things differently.
i personally am very optimistic that things will improve, i see our children and grandchildren with a consciousness of realization of being at one with our planet.
exploitation gets replaced by integration= a good outcome, don't give up hope because we all came here to change humanity for the better.
Got any evidence Will or peer reviewed papers to back you up?
I only see a grab bag of half baked conspiracy and assertion.
Reading Wills reply to Terminal above, after he belittles those who don't accept his views as dumb lay opinions fed by the "left" media which "dominates" opinion in Australia, it seems the papers that he relies on are those produced by the Murdochs.
Also note he hasn't yet divulged his qualifications despite three posters asking him, seems he can't respond to those posts but is happy to imply that he has some greater understanding of the science that the rest of us are incapable of comprehending. As I suspected from the beginning, the issue is part of a left/right culture war to Will, not a matter of the survival of the animal kingdom and the trashing of the planet, which it is to me. And just to keep my posting consistent on this topic, if you are reading this Will, go and get fucked.
It's a subject worth arguing about ,
If you have five minutes ...
That was nowhere near five minutes tubeshooter.

Makes sense more south swells as lows drop further south, also expect to see more cyclone activity and swells as the sea temp window creates a bigger playing field.
Change is change it brings good and bad, going to be interesting to watch all this play out if it happens as many (but not all)
scientist predict.
One thing for certain if it does play out there won't be any stopping it, we can do what we can, but population increase and the continual transition of developing countries to developed countries(high consumption societys) will counter act any positive steps forward.
And no that doesn't mean we don't try, as if real it will still slow things down, but just got to be realistic.
Anyway good to see some balance in the post here, pity not all can respect views they may not agree with.
love your work TBB, ant"s without brains are a good thing. . remember the level of awareness is what really matters right here right now. as i said to a brazo whose's wife is studying encironvioronmemal science. thank the negative, but never forget your role in being an agent of sustainable positive change. as u said, swelnet allows us to share without censure unless we are being nasty, really nasty- - thanks , thanks , thanks.

Always liked the saying - may not agree with you but will fight for your right to have your opinion - or something like that , all part of enjoying living in a democracy and being part of swellnet forum.
When it comes to climate change, governments have failed and are unlikely to lead, the press has failed and is to closely tied to those who benefit from fossil fuel money. I'm not prepared to give up without an effort gotta look those grandkids in the eye in a decade or 2.
The link below is to an Australian group who are combining individuals power over large organisations to try to bring about the shift away from fossil fuels. We all have super we can all direct our super funds not to invest our money in Coal and Oil.

Voltaires' biographer, Evelyn Hall, came up with "I don't agree with what you say but will defend to the death your right to say it", reflecting his view of free speech. A similar Hall/Voltaire quote is "If every man did the little he could, what a different world!" which also seems appropriate to the link you provided.
Plenty of scientist debunk the man made global warming scam .. the seas aren't rising .and climatologist say it will likely be a cooling period. Also when the Earth was a few degrees hotter during the Medieval warming period it resulted in a time of prosperity .. things grow better .. animals prosper. Stop pushing the Globalist propaganda aimed at robbing $$ from masses, power and control.
Scare mongering does not work .. and ridicule is even worst for convincing people of this global sting operation.
plenty of scientists?
Like who?
Lets see some actual peer reviewed science to back it up.
Any intellectually honest reading of "follow the money" points to fossil fuel shills and grifters like Clive Palmer spending 60million on election advertising to sway the election.
I don't believe for a second that this Will Smithson is an actual scientist. Just another internet astro-turfer.

Scientists questioning the accuracy of IPCC climate projections. These scientists have said that it is not possible to project global climate accurately enough to justify the ranges projected for temperature and sea-level rise over the 21st century. They may not conclude specifically that the current IPCC projections are either too high or too low, but that the projections are likely to be inaccurate due to inadequacies of current global climate modeling.

Impressive list, these guys must be the 1%. Lot of non-experts (not to mention retirees) in climate science in there too, you wouldn't get a plumber to give you advice on your house's electrical wiring would you? I reckon one could generate a similar sized list of scientists that think vaxxing causes autism...
Terminal not busting your chops but you highlight my point. And that why there'll never be divergence to overall agreement.
1. Impressive list, these guys must be the 1%.
Opinion yes fact unproven.
2. Lot of non-experts (not to mention retirees) in climate science in there too,
Again opinion. Factually that list (if true) indicates many specialists in fields all
relating to climate science.
3. You wouldn't get a plumber to give you advice on your house's electrical wiring
would you?
Well No. Of course not. But I would ask a retired electrician. And while a botanist
in principle may not be my first consult in relation to climate science ,
meteorologist, atmospheric science biologist, oceanographer; paleoclimatologist,
atmospheric scientist, physics focusing on astrophysics and climate science are
generally akin to understand the chosen topic.
4. I reckon one could generate a similar sized list of scientists that think vaxxing
causes autism...
Possibly so, but relevance? Apart from casting dispersions by using another
topic where generally based on numbers antivaxing is nuts why use that as an
angle to justify the position?
You see my point is, until we on both sides of the CT debate are able to respect and debate on relevance and fact the arguments from either side will never be won. I believe, I seriously believe, that the internet/social media will wipe us out long before CT does.
The cliche line is 95% of scientist agree on man made climate change.
What do 95% of scientist actually agree on?
Basically open to the fact that man has possibly some impact on climate change.
Those included in that 95% are also some of the most vocal that mans influence is very minimal.
Yep undeniable that man has had an effect on CT imo. 30 years ago I used to watch my old man poor 100s of ltrs of oil down storm water drains. Yet now, if he was alive, his actions and many others would be far more eco friendly. So in that instance on its own, man had a negative effect but now based on understanding and education and simply being law abiding have had a positive effect. Whether the question of CT leading to unstoppable and catastrophic end is the question I hope a respectable debate and assoc science can prove one way or another. In the meantime can we all just pick up the rubbish we walk past!!
Impressive thread.
I think that 2 degrees hotter will be very noticeable, if you live on the land in a hot dry climate where the trees barely survive summer.
I may still get to shipsterns one day
Man it’s gods will to soak and flood the yuppie wankers who live in multi million dollar homes on the coast and don’t even surf, fish or walk on the beach man.
If I get hot I sweat noticeably more moisture on my skin the win blows and cools me down.
If earth gets hot there is noticeable more water wind blows cools it down man.
I guess the the earth gets hot water rises wind blows cools down and I surf new breaks with no yuppies and hipsters God’s will man.
Will (and entourage), I'm having trouble following both your logic and your science here.
Firstly you quote questionable historical stats to make it sound like the modelled and observed SLR is nothing to worry about. Perhaps check https://coastadapt.com.au/how-climate-and-sea-level-have-changed-over-lo... from a source which is highly reputable.
Secondly, you don't say what kind of scientist or doctor you are/were, and then go on to say that you're pretty much self-taught in maths and related work. I'm struggling to see qualification here - you might be able to regurgitate textbook maths/physics theory at us, but you don't really tie it in.
You've been challenged to rebuke the established science with solid references, but you duck and weave. The science isn't really up for debate anymore - https://climate.nasa.gov/scientific-consensus/ - although it is noted that there are a range of "organisations" challenging it via skepticism eg https://skepticalscience.com/team.php . I think we can all agree that if we were to line up one side (let's call them the home team - the climate scientists, national academies of science etc) against the skeptics (who we might call the visitors, and which include brainiacs form the aforementioned site who open their biographies with gems like "In the 70's I had a dinosaur book...") then not only would the home team numbers dwarf the visitors, but they'd eat them alive on brain power in a 1:1 game.
Spookypt, I think you are taking your list completely out of context - it is one thing to disagree on the exact outcome of a modelling process and/or suggest that the data etc doesn't exist to predict with the necessary accuracy, but entirely another to imply that those on the list are sceptical of warming and the need to address it.
As someone who works in the space and with scientists across a range of disciplines, the key issue for me is that there simply have not been adequate rebuttals of the overarching problem from the sceptic community. No reputable scientific publisher will fly their flag. The peer review process won't let the vast majority of the papers submitted past the first doorway. If there was sufficient evidence to change the course of the issue it would be here now. 50 years is enough time to get the primary issues sorted and start to make a move.
It brings a tear to my eye that my kids feel like they have to strike at school because people are too selfish, won't respect the science and think the rights of future generations are a chip on a blackjack table.
To channel a bit of Adam12 - get on with the evidence, or shut up and fuck off out of the way so that good people can make the changes we need. Ironically, you decry insults all the while completely ignorant of the immense insult your un-substantiated resistance to peer-reviewed science is to everyone with an interest in the future of the planet.
Tango, thank you, from the bottom of my heart, thank you, for articulating what my rage and anger with the Wills of this world prevent me from articulating. Wish you the best.
Your links don't really back your arguments?
I don't think many deny climate naturally changes, but to what extent is man influencing recent warming?
All your post seems to do which is a reflection of the bigger debate is mock and shut down anyone that has an alternative view point, this currently a huge problem, because its no longer about science but more about politics and money.
Quite the contrary, Indo, I'm simply trying to throw down the gauntlet to the sceptics to put forward some published, credible evidence which any rational person could get behind. You give me an alternative view backed up with facts and not opinions and I'm right there with you. After all, the sceptic community have had 50 years to prove it wrong with a mighty carrot from fossil fuel funding and they remain marginal at best. Even Murdoch can't sell it.
Indo....try reading the history of Exxon , how they worked out fossil fuels are heating the planet, how they can profit from Climate change , and how they set up lobby groups telling everyone that fossil fuels have no effect on global warming , while their own reports show the opposite.....
how did you like the Adam Goodes doco?
Indo duh ...I forgot to post the link, So if Exxon has proved that fossil fuels heat the planet , and then lobbied from to get people believe the opposite of what they proved...boy there are some gullible peole out there!
https://insideclimatenews.org/news/15092015/Exxons-own-research-confirme...
Kind of confused about the Adam goodes docco, Adam didn't seem involved or even want to have much to do with it and im not sure what the point of it was, it was almost like trying to re write history it was a timeline of events that left out some aspects and tried to paint other in one light or perspective.
Anyway i gave a more in depth review here https://www.swellnet.com/forums/politico/14821?page=6
Sorry been surfing; Lennox was pumping to day :-))))
My goodness, a thoughtful but snide comment ...
Sea levels Facts:
1: Sea level rises and fall about 140m with each Ice Age
2: The last rise was about 130m/10,000 years = 13mm/year. current sea level rise ~1mm/year = nothing to worry about ... its probably going to get worse!
http://joannenova.com.au/2019/08/sea-level-scare-industry-urges-plans-to...
Not that is matters but UG in chem/physics, PG in CompSci, more maths more than most so called "climate scientists" have!
Consensus in science is BS!
The so called 97% consensus is also BS: read the story of how that came about.
There was consensus before Copernicus and Einstein too! It only takes one: if you are wrong you are wrong! There was consensus about CFCs and ozone: they were wrong: once chemist working in a tiny lab in Germany proved them all wrong!
Models: are the ONLY evidence that gives rise to the cataclysmic Armageddon scenarios. We have been hotter and more CO2 before: much hotter and much more CO2 ... So EVERYTHING is based on the models! If they are wrong EVERYTHING is wrong! The models are based on mathematically provably wrong principles: we know this for a fact: we do not have initial conditions and we do not have boundary data: the models are WRONG: EoS!
We also know they are wrong because even the difference between the predicted and absorption anomaly of 25-30W/m^2 is greater than the WHOLE CO2 contribution!
THE MODELS ARE WRONG!
The Problem With Journals:
1: many of the journals are controlled by the very people who now have vested academic and/or financial incentive in AGW.
2: This is further complicated by the "Messianic" saving the world of the eco sciences where facts have given way to quasi religious principles rather than science (much like yourself by the tone of your post!)
3: Secrets: like the East Anglia CRU who held the worlds ONLY un fudged pre digital temperature records conveniently "losing" them after the FOI court win; or the secret GCM models: ask CSIRO/BoM for a copy of the code or data from the latest model runs.... NASA GIS is the only GCM code that is available: all the others are SECRET .... since when did we allow secrets in science publishing!
So basic data is secret, code and data for the GCM models is secret, initial data for the models is secret, algorithms for lost of things like correction are secret ....
And then we have academic coercion .. look at Bob Carter and Peter Ridd cases just to name 2 recent ones in one university ... don't dare speak aloud that AGW might not be true otherwise we will just terminate you!
And then we have funding for research into non AGW ... good luck with that as its handed out by politicians!
BUT if you read the IPCC report ... not not the Summary for Policy Makers which the media and pollies quote but the actual Scientific report a lot of this was in there until the most recent one henceforth it has been purged: nor more dissenting views allowed!
Hard to publish but it's there in the hard core maths, chemistry and physics journals
Rebuttal:
This was always the premise with AGW: we don't have to prove it is true YOU have to prove its false .. so when did the burden of proof reverse .. when it became politically convenient of course
Sadly I have seen over 40 years of research (in biology/medicine) the almost complete corruption of firstly the grants process and then the publication process and finally the implementation of blatant censorship at universities to appease the political agenda rather than good science. This is especially true for anything related to climate science!
I've said enough .... I got a flogging at Lennox today and I'm stuffed
Plaudits for the response, Will, and hope you got a few at the ox. I miss it.
I wasn't intending to be snide, though I am completely fed up with the lack of evidence from the sceptics and the hand-brake the sceptic community feel justified in placing on action to deal with the problem. I'd have settled for openly contemptuous.
As to your facts - please, can you cite reputable sources?
Re 1. are you suggesting an average SLR of 140m across all ice ages? What is your source for this?
Re 2. As I understand it, the sea level rise since the last ice age occurred over more than 10,000 years and there's some thought about it occurring in waves rather than as a constant (https://www.giss.nasa.gov/research/briefs/gornitz_09/) , so your reference to an average appears both excessive and designed to mislead.
Re 2. You also state that current SLR is approx 1mm/yr.....Donald Trump's own NOAA reckons that " The pace of global sea level rise nearly doubled from 1.7 mm/year throughout most of the twentieth century to 3.1 mm/year since 1993." (https://www.climate.gov/news-features/understanding-climate/climate-chan...). It would appear you have downplayed it by a factor of three times.
If Jo Nova is the best you can do, it is no wonder that the sceptic community are not taken seriously.
If I read between the lines am I right in thinking your problem is just with the models? Your undergrad in chem/physics suggests you know a bit about part of the climate debate, but the computer science post-grad suggests your focus is the modelling and maths, and I'm not sure how far down the rabbit-hole your concern goes. I'm also concerned that a disproportionate number of the sceptics on that website are computer scientists.
CFCs and ozone was wrong...? That would be quite a headline. Can you please provide a reference for this?
If the models are wrong, surely you can't; suggest that there is a full-tilt worldwide conspiracy to stymie the process of peer-review? I'm sorry, but I simply cannot see the vested interests for climate mitigation and adaptation having anywhere near the clout of the fossil-fuel industry and its acolytes. Again, if you could point me towards some solid information rather than opinion...?
I also struggle to see your overarching point. We have coasts actively receding, we have places going underwater. Tectonic rebound might be making some places "higher" and dryer. When previous sea level rose higher than today and/or at faster rates than we are currently experiencing, the simple truth was that we didn't have the people, the infrastructure and the hard lines on maps. Everything could move and private property was a glint in the eye of a capitalist caveman. What do you propose happen to the millions of people who are becoming impacted by rising seas? Or by increasingly intense storms? The world doesn't work the same way it did in 10,000bc when the sea was coming back up. It's different, and I cannot understand why you'd stamp your foot like a toddler and say the models are wrong. It's bloody-well happening now.
I share your concerns about the politicisation of science, but do you seriously think 97% of climate scientists are so cowed by job security that they will go along with a con? It sounds more like you've been burned in some way by the science politics and have an axe to grind. I also cannot see how you can think that conservative governments around the world and in Australia for much of recent history have pushed a pro-climate agenda.
Anyway, I'm over arguing, it's making a flogging at Lennox sound easy.
Re 1. are you suggesting an average SLR of 140m across all ice ages? What is your source for this?
SLR:
Yes, it varies from 110m to about 140m .. is part of the standard geological record in any high school text book.
Time: yes the emergence from the last Ice Age was longer than 10k but the SLR rise (due to thermal expansion and melting!) only really occurred over the last 10k. ditto for other IAs as well: hence the "waves" of SLR
The Nova article has the references to the worlds tide level gauge records for a long time. Its what is said and proved rather than who says it!
Computers
The concern is because CSs understand that the numerical analysis component is part of the problem and they understand the issues related to solving IDEs in a converging system in a numerically limited environment ..... something even many maths majors do not! FORTRAN is designed to assist (all operations are Epsilon safe for example) but you cant get around the fact that in a converging system there is a limit to precision!
It is well know but convenently ignored that the models are WRONG .. they cannot be right for a whole lot of theoretical reasons including those I have mentioned but the single biggest one is that they dont match observations: whether its stratospheric temps at the top end or incident radiation at the surface; the errors are so large as to render the models useless UNLESS we fudge them so they add in "fake" clouds etc to make the models agree ... its just BS!!!
Funny isn't: the rate of ClO. radical was out by a factor of 10 and surprise surprise the computer models were wrong! If you profess an interest in climate and do not know this then I suspect you do not really have in interest in climate: YES CFCs did NOT cause the ozone hole: old news!
Coastlines:
IF we progress as per the last Ice Age then the sea will rise another 30-40m ... its already risen about 100m since the last Ice Age and we are well OVERDUE for this further rise ... NOTHING humans do will stop this happening!
OMFG the ol "97% of scientists agree" are u seriously using that BS "internet poll" to me ... that's the worst insult I've had here ...
Simple Summary:
1: the seas are going to rise another 30-40m in the next 1-2k years, that was always going to happen cos we are emerging form an Ice Age and we cant stop that
2: the computer models are interesting toys for predicting the weather for a few days ahead but are useless for climate modelling 20 years away
3: we are going to run out of fossil fuels in less than 100 years and unless we find an alternative energy source there wont be any surfboards to surf on: we will be back in the caves so stop spending our science budget on stupid useless feel good hand waving value signalling BS and spend it on basic physics/chemistry for solar PV/thermal/Thorium reactors/fusion/better batteries etc etc
PS to whomever it was 12 somebody yes I am an old scientist, and I surf Lennox at 6-8 and I still ride dirt bikes (a 300, 500 and 650) .... now fuck off yourself you ignorant prick!!
Do you ride a mat out at Lennox , or are you just a local who surfs when lennox is only BIG?
George would have been proud of me ... yes a mat .. I didn't have a real good one .. got slapped first up and put me off a bit but my son was out there too .. he got some magic classic Lennox bombs .. was hoping someone got some pics but haven't seem any yet .. Not a local .. from up the road a but but come to Lennox when the southerly is in town....
Onya Tango and adam12, I hear ya's.
freeride76 said "I don't believe for a second that this Will Smithson is an actual scientist. Just another internet astro-turfer."
Yeppo.
I remember seeing his first post, noticing his profile pic and straight away thinking "on ya bike!"
doesnt take long for the beliebers to trot out murdoch in these debates..no matter how much evidence one side has, the other side will call bs, say its not 'facts'..peer review also always comes out..97%....its worse than religion these arguments..
Thanks Will for making the effort to post here and bring some good points to the table.
I really don;'t see anything from Will except assertion.
and if he has any scientific training at all he'll know assertion is useless.
He says the models are wrong.
Yet models can only really be assessed as to their usefulness, ie their predictive power.
In this case, their predictive power has been broadly correct.
the basic science is understood and the models have predictive power.
So tell us again Will why the science is wrong?
Add to your comment FR Wills comments on solar / batteries / power sources are complete rubbish.
The earth says....
Just keep spinning spinning spinning,
Just keep spinning spinning spinning!
With all the concurrent climate/environmental catastrophes happening here and abroad, arguing that climate change is not real or action should not be taken regardless of perceived economics, and basing your argument on the accuracy of predictive models doesn’t make you smarter or more informed than those around you. It makes you wilfully ignorant.
This is where it gets weird, lets put aside whether man influences climate change or to what degree.
But this mindset that any current drought, flood, fire, hot spell, cold spell, cyclone etc. is a result of man made climate change is just crazy. (The only valued arguments here are more localised influences, like fires from man, poor land management in particular water use, like issues with river levels)
Otherwise sorry but these weather events have and will always happen, even in cases where there might technically have been more events in the last 20 years of so in an area its so minimal that it can only been seen in data, not some mindset that oh, a flood happened today its a result of climate change.
But that's where we are at, we have shit loads of people thinking their own observations during their lifetime of weather events is science and credible and everytime we have any kind of weather event, its a result of man climate change and then these same people mock others that question mans ability to understand or predict something as complex as climate change.
FFS we couldn't even get a the Y2K thing correct a thing 100% created by man.
Tell us, those that believe we need to stop talking about if it’s true and start enacting what we have to do, what else has to happen before you believe we have to start making changes to the way we operate, and that our government should start taking climate change seriously.
What other catastrophe or scientific evidence and produced by who would change your mind.
And should the rest of us wait for that before we do something?
Y2K.........really?
You missed the point your trying to argue man made climate change is real because of certain weather events you believe are not natural here and abroad.
Which is pure BS and far from scientific and in the same post ironically call those that question the climate models wilfully ignorant.
Anyway no matter if this all turns out to be another overcooked Y2K or another hole in the ozone layer thing, we will have to wait and see, we really won't know for some time.
One thing for certain we should all be hoping its not as some say because only one thing is 100% certain, the world population will only increase and as a result at best even with action emissions will slow but never stop.
Indo try reading this one on climate change and how the scientists are right....
https://www.theage.com.au/environment/climate-change/the-amazon-fires-an...
That is exactly the kind of article that fuels this ignorant type hysteria of trying to link any and every weather event to climate change, straight out bad science no facts or figures.
We all know deforestation is a huge problem and its fueled by an ever growing population with an every growing culture of high consumption, not climate change.
Any rise in forest fires is also much more likely to be a direct affect of man in that area, not the affect of man in other areas of the globe.
It should be noted deforestation in itself can change regional weather that could possibly affect other regions climates though.
Another thing to note, despite deforestation and urban sprawl etc. NASA own satellite pics show we are actually seeing many areas green up due to higher C02 levels in contrast to what the article states.
And BTW where's this higher number of cyclones and cyclone swells?
And where is this drop in ocean front property prices?
So you use one small part of NASA information regarding climate change to support “it’ll be ok.........I hope” and ignore the rest of what they say. Including the links between weather events.
There is two things.
1. Theorys and ideas, many of these things in time end up being incorrect.
2. Indisputable evidence, like satellite pics where you can compare two pics from two different times and see changes.
I have no idea if long term it will "be okay" or if man has an influence on climate and if so how much.
But yeah id like to be optimistic and believe its all over played, because if its not, there is nothing we can do about it, i know people want to believe they can make a difference, but sorry you can't, despite the fact Australia's carbon emissions are tiny on a world scale.
Even if the world some how did all things needed, sadly the continuing increase in world population and increasing consumption deforestation etc. will counter act all efforts made.
BTW. That said im still a supporter of good sustainable environmental practises and support a sensible transition to renewables, it just makes sense as the tech evolves to embarrass clean energy, its just a progression of technology.
They are not theories and ideas, they are proven and correct. Full stop.
Far far from it.
Ok so one simple question then what percentage of climate change is caused by C20 produced by man?
Humans emissions and activities have caused around 100% of the warming observed since 1950.
Ok Andy so since 1950 the natural warming of earth coming out of ice age stopped and switched over to 100% man made warming?
You really believe that?
Its highly likely C20 released by man is adding to natural warming but its still theory and in the future we may discover other natural or man made influences at play.
BTW. I did google my question and can't find anywhere that can give a percentage idea of how much warming is natural and how much possibly from man, did get a figure though on percentage of C20 compared to other produced gases from man that are in the mix C20 only 65% and some of the other gases are predicted to be much worse in their effect on global warming..
First principles, increased CO2 causes warming of the atmosphere, the flow on effects go from there. % I have no idea.
Questions like the above are made just to try and justify your misinformed point above.
Indo you could answer your own question very easily by copying and pasting into a search engine but it's pointless because your opposition is driven by ideology and so you're not open to an answer.
One thing I will grant you - every time there is a bushfire, flood or storm, for the press or whoever to state that it's definitely a sign of global warming is a stretch that doesn't help the cause.
yeah , agree with you on the media AndyM . We all want better but convoluted hysteria won't win the masses.
https://www.betootaadvocate.com/headlines/brisbane-residents-fire-up-the...
Judging by the predictions I imagine Red Bull is sponsoring some of the research.
But from a Johnny Cochran of science , "The models were wrong , If they can't explain the pause , they don't understand the cause.".....can't remember who said it and I don't give a fuck either , I just thought it was some funny shit to say to lighten the mood.
suit up
Indisputable evidence, like global average temperatures rising each year.
All the info is out there Indo, but you need an open mind for a start...
"Skeptics of human-caused climate change have often relied on a favorite argument involving the planet’s natural climate cycles. Earth experienced plenty of natural warming and cooling phases long before humans ever began pumping greenhouse gases into the atmosphere, they’ve suggested—so the present-day warming isn’t necessarily dangerous or even that unusual.
Scientists have debunked this argument over and over again. Studies demonstrate that carbon dioxide concentrations are currently higher than they’ve been at any point in human history, global temperatures are rising at unprecedented rates, and warming is poised to surpass anything the planet has experienced in millions of years."
https://www.scientificamerican.com/article/current-warming-is-unparallel...
Leaving aside the corrupted Temperature records that we are using for comparison .. 2000 years is nothing but an infinitesimal blink in geological terms and meaningless in the context of the earths 2,700,000,000 year history ...
Cherry picking.
Much more than 2000 years -
"global temperatures are rising at unprecedented rates, and warming is poised to surpass anything the planet has experienced in millions of years."
Also, if you want to think that the earth is 2.7 billion years old then you're seriously undermining your credibility.
Actually folks it will be the changing oceans pH that will destroy humans (not disputed BTW) and many other species pretty much a sure thing ...............but as a mate keeps pointing out to me the earth will carry on very happy without us, the earth knowing the human experiment failed.
Indo, google ocean acidification caused by the uptake of carbon dioxide.
I had sort of said my bit but this sort of utter gibberish just cant go unanswered.
Without any science but just logic we know that CO2 has been up to 20x (no thats not a typo 20x) current at up to 8000ppm and yet life on the earth and the oceans not only survived but thrived!
But if u want the science try here: http://geoinfo.amu.edu.pl/qg/current/quageo-2019-0029.pdf
Science? you are kidding its a incredibly poor article more Fox TV than science but not as bad as your statement below .....absolute shocker, more Fox TV,
"At best we have about 50 years of oil left and 100 or so years of coal left. If we don't find an alternative energy source its back to the caves for all of us!
And no solar (PV or thermal) and wind will not cut unless we find some miracle battery (unlikely cos we know the chemistry of batteries!) so we need something else .. probably fission then Thorium in the interim and then hopefully fusion ...
So stop wasting our last few precious years and resources on stupid emotional politically driven Green BS (which is what we are doing at the moment) and spend it on good basic science instead because thats the only real solution other than back to basket weaving!"
A non-peer reviewed paper titled "The Hoax of Ocean Acidification" seriously...
You haven't read it ... It was a laymans (not too technical) explanation of why acidification scare is BS.
But the simple argument is: currently we are at 400ppm CO2 .. we have been at as high as 8000ppm and life on the earth and in the oceans thrived at that time: there is a reason for that: it's explained in nice simple non scientific terms (which is why I used that article).
But as usual ... not a single argument, debate or question: just ad hominem attacks on people, ideas, integrity ... never actually address the issue ...
8000ppm, not in the lifetime of humans as we know it.
Not sure how anyone can dispute this graph or see it as not the trigger for global warming with temperatures going up year on year and long standing historical records being broken.. The greenhouse effect was discovered in the 19th century.
No but it during the greatest proliferation of life both on the planet and in the oceans including several Ice Ages ... it's only the plants sequestering CO2 that reduced it ... its all about time scales and graph scales
Not sure how to put an image here but have a look at the pic here https://stevengoddard.wordpress.com/2012/05/31/ice-age-at-2000-ppm-co2/
The point is that CO2 levels much much higher then now have not been catastrophic in the past, anything but! Its only the computer models, which we know are wrong, are telling us that!
As to T records thats another debate but suffice to say that all old records were conveniently "lost" and of you understood how pre digital records were obtained and kept then you would seriously question what we are comparing to to say "record warming"
"we have been at as high as 8000ppm and life on the earth and in the oceans thrived at that time"
How did mammals fare?
Humans?
Will, calling others' contributions "gibberish" flies in the face of your earlier implied rules of engagement re me being snide.
I cannot believe that you try and pass yourself off as a legitimate scientist when the only science you can point towards is an obscure journal from a Polish University. In the current edition there's another article by the same author from the Uni of WA who has teamed up with an "independent scientist" and done an article on why the Pacific sea level rise is nothing to worry about....and I quote from their Exec Summary: "The Pacific Atolls are not being inundated because the sea level is rising much less than was thought." Mind you, while they authors rely heavily on a very select group of other authors including a few who would appear sceptical to climate, based on the titles of the papers, they do appear to have had a few of their more mainstream thoughts published in reputable journals such as Ocean and Coastal Management. Though I'm sure none of that brings any comfort to the people of Tuvalu.
If we were to accept the arguments put forward by the well-meaning folk at Real Science (which is the only reference I can quickly find for your 8000ppm figure - https://stevengoddard.wordpress.com/2012/05/31/ice-age-at-2000-ppm-co2/) who are actively campaigning that climate change is a hoax and have a tagline that "science is the belief of the ignorance of the experts", then surely we also have to accept that back in the day when concentrations were that high the world was a very different place. According to them, it was 450 million years ago in the Cambrian period.
If we accept that, perhaps we could also compare the current state of the world with some of the things we know about the Cambrian. Rather than today's geography we had Gondwana. Rather than todays biodiversity, it was the time of trilobites and very primitive organisms, and there was a well-documented "explosion" of evolution according to the fossil record (which can't easily capture organisms without hard structures). The Cambrian lasted some 55 million years, which is a difficult timespan to comprehend.
Regardless of what conditions were like at any time, we now have billions of people on Earth to house and feed. We now have hard structures, property rights, infrastructure and the like which are built and insured on far shorter time periods. We don't have the luxury of even hundreds of years, let alone millions of years, for the ecosystems or human systems to migrate back and forth across landscapes in response to wetting/drying/cooling/heating cycles or sea level rise as they have been able to do in the unpopulated past. We do not have the capacity to adapt except at the margins. Arguing about the models doesn't change any of that.
Everyone agrees that climate science and the potential responses by the biophysical and anthropocentric worlds are very complex, but to try and put forward suggestions that it's not happening because the models have a mathematical flaw, or saying it was worse than this millions of years ago....it's beyond puerile, and betrays ones ignorance of the situation. To then try and sow seeds of doubt to obstruct people taking action through their governments is just criminal.
It's helpful to apply the tenets of risk management to this issue. Likelihood and consequence, that stuff. I'd be surprised if we couldn't accept that the potential risks are severe (I'd argue catastrophic as they go well beyond the physical). As for likelihood, I'd say its certain as it's happening now while you might say somewhat likely due to natural variability (as you say it's happening in response to a warming cycle and therefore more slowly). But even a severe risk which is somewhat likely to happen gets at least a high risk rating. In my world it gets a very high/critical rating given that it's deadset happening. So are you suggesting we have a high risk that at best we should do nothing about - or at worst keep on doing more of the stuff that experts believe is contributing to the problem?
So quibble about the maths underpinning the models and deny their alignment with observed trends, rage against the machine and cite sources from The Muppet Show, but keep it to yourself.
Screaming that we are all going to die is gibberish! Its nothing but quasi religious "repent now" BS!
As I said the article was in laymans terms why "acidfication" is BS! Theres no point in real science here because most either wouldnt understand it or dont have access to journals.
The levels of CO2, global temps are accepted universally by recognised techniques (usually radio graphic/isotopes) but there are errors in this.
The simple fact is that plants and animals using the same biology as we do survived and thrived in environments which according to the computer models they could not have survived: the models are WRONG!
As I said above ... we will run out of fossil fuels long before we are affected by climate. Lets stop wasting time and effort on BS precautionary stuff based on flawed computer models (which do NOT align with observations without massive fudging!!) and fix what we KNOW for certain is going to happen: running out of energy!
"...just ad hominem attacks on people, ideas"
It's funny when you say that, you could almost think you haven't done exactly the same thing yourself.
I have not abused anyone, called them names, challenged their honesty and have always addressed the science (within the limits of this forum)
The only "attack" is perhaps to condescend to people commenting on scientific issues they obviously have not the slightest understanding of. In other words they are talking religion/faith rather then science!
How do you know people haven't the slightest understanding what they're commenting on when you only know their account names?
Because their replies either don't debate any of the science or show profound ignorance e.g. we are all going to die CO2/seawater pH rubbish above ...
Hi Will,
Appreciate your input to the debate here; please don't stop.
156 comments and counting. Do you feel you've changed any opinions? Is there a better way we could go about this?
Personally, you haven't convinced me but at least you have given me some further points to research. I think it would help if you kept your arguments technical (as opposed to emotional) and provided more reputable references.
Otherwise, keep it up. Science is built upon a foundation of people not afraid to swim against the tide!
The problem is that the science is SO VERY complicated that even the really bright intelligent scientists cant do it ... the combination of skills and knowledge across classical and quantum physics, organic and inorganic chemistry, arcane areas of mathematics, difficult numerical analysis related to converging systems, IT, geography and geology, hydrodynamics and aerodynamics, astrophysics, weather and and arcane areas of atmospherics like gamma ray accretion etc etc etc
We have to reply upon the very few experts and there are literally a handful of people in the whole world who would have a handle on all of this ....
The there is the political angle to complicate this .. look for example at the actual early IPCC Scientific reports then compare them to the Summary for Policy Makers (the latter is created by politicians and is the one the media/pollies see) and its like they are two different documents: they bear no resemblance to each other! Now that has been corrupted as well: the actual scientific report is not released and is back edited to be consistent with the Summary report which is released first.
All I want is
a) for people to firstly separate the politics (Green/left/socialist) part of the debate and its fine to agree with the socialist ideals for society (personally I don't agree, socialist states always end murdering and torturing too many of their own citizens but that's another argument) but don't use AGW to support it
b) to be sceptical of the so called scientific reports because most of them are built on the assumption that the climate models are 100% correct (all the warming is due to AGW) which we know they are not but seems to have been conveniently forgotten!
BTW Im not convinced either way either! I do know the models are BS for two reasons which are so long winded but basically some comments one of the few geniuses Schmidt made in the NASA GISS model code about models behaviour when you reduce the spatial/temporal resolution too far: a sure sign the model is broken (Schmidt is pro AGW and Hansen's right hand maths/coder!!) and I was also a friend of someone who worked as a numerical analyst/mathematician on Australia's GCM models at ANU/BoM/CSIRO ...
"The problem is that the science is SO VERY complicated that even the really bright intelligent scientists cant do it ..."
Hi Will,
Is that why Clifford Ollier in his paper,references people like James Delingpole, a second rate urger trying to pass himself off as a journalist.
And don't get me started on that fruitcake Jo Nova.
Will, it's not that we're all going to die, it's that the food and farming belts will shift and many will go starving. Changing climate means some regions will see increased rainfall and others, less so but all established agriculture and pastoral land will likely have to shift.
Water security is already an issue in a country as lucky as Australia and all these issues will only get worse. We need people to stop attacking the proven science and move on to how we're going to deal with these changes..
Ok now we get into a debate:
1: what you said is true but that was going to happen ANYWAY! If we keep going as per the normal cycle the temps will keep rising by about 1-2C, the seas will rise by about 30-40m and previously this last phase has happened very quickly <1000 years. But I have based this on past history and geology whereas you are basing EVERYTHING on the computer predictions which we know are WRONG!
Water security has always been an issue in Australia for the few hundred millennia .. we can clearly see the records of droughts and floods in the geological record which make anything experienced since white man came piddling by comparison! And again your assertion that "its only going to get worse ..." is based on the damned computer models again!
But in the end I agree: lets move on and deal with the most urgent and pressing issue: RUNNING OUT OF ENERGY: ENERGY UNDERPINS EVERYTHING IN OUR WORLD including food water transport ... just everything ... without it we cook hunted prey on a campfire!
I'm not basing anything on computer models, I'm going off pure observational data and records and what I can see with my own eyes.
So what you are saying is that you are using observational data to predict the future climate. Generally I would have no problem with that except that what you are using is corrupt data.
Lets just take one example: T data in Australia. Neglecting for the moment that the actual RAW T data for Australia is secret (no you cant have it, you can only get the "corrected" data) lets have a look at how that data was collected before the digital era: it was collected by untrained Police/Post Office/School workers on un calibrated equipment and sporadic records kept by hand and occasionally transmitted by hand/telex/telegraph/phone to the central records of the BoM which only started in 1910.
That data was collected in the sporadically placed backyards of government buildings in unprotected boxes where anything from ACs to chimneys/flues to motor vehicles to a person to new concrete buildings to animals (yes birds often nested in the thermometer boxes!!) could have increased the T readings.
And if you think the post digital era got better think again because the whole energy using society really got going with masses of industrial heat generated right around where the vast majority of the measuring stations are situated!
The only reliable data and even that has issues is satellite data which has only been recorded since the late 70s! So we have about 30 years worth of data as we emerged from a cool period (remember they were predicting an Ice Age after the 70s cool period!).
No seriously this is the quality of the data record you are using to change the very fabric of the whole world on a 0.1-0.3C comparison!!!
PS this is just the surface data ... atmospheric data is even worse and the methods used to collect SST are nothing short of surreal!
Hi Will,
BOM raw data is freely available.
Globally the raw data shows a higher warming trend than the homogenised data.
That is is the adjustments made to raw data have reduced the warming trend.
And then there's Roy Spencer's data. Strung together from about five different satellites which had to be corrected for diurnal drift amongst other things, which Roy wasn't aware of until pointed out to him. He will not release his code for the latest version which just happens to show a greatly reduced warming trend, compared to all other data sources. Even so, his trend is plus 0.13C per decade.
Only the corrected data is available!
RAW data is generally not available and never has been!
When the UN IPCC repository at East Anglia CRU was ordered by the court under FoI rules for the RAW data for the IPCC after years of court battles the RAW data was suddenly LOST! Read the "ClimateGate" emails! So we can never know what the real data was!
Satellite data is better controlled and the albedo/diurnal (and several other factors) but still just like the secret UHI algorithms used to "correct" the land data the satellite algorithms are also secret!
Hi Will,
Re your comment on raw data see:
http://www.bom.gov.au/climate/data/acorn-sat/#tabs=FAQs
Refer to Question 6.
Hmm that's new, they have only done that only recently .. It was always the "munged" UHI (secret) corrected data which is what they use for the "hottest year" ever media releases.
However its only Max and Min .. think about why that's a problem (could be aberration like a bird/rat in the box or a new AC across the roof ... pushing the T up). But its still a good thing. I assume a researcher can get mass digital records including general locations (they keep the actual locations secret for obvious reasons). and the data only goes back a few years .. about 20 in most stations!
However this is not true for most countries and the UN IPCC CRU has steadfastly refused to release RAW data (see Climate Gate).
Please, drop the talk of conspiring of governments to adjust records upwards, and for what?? They're not even taking climate change seriously so who's winning out of this so called conspiracy..
The world's governments can't agree on anything let alone setting up and manipulating temperature records..
Can’t agree on anything ?
Western governments are basically in lock step . Those who fiddle on the margins are called extremist.
It’s neoliberalism and mass immigration all the way .
Trump is an outlier the global establishment has attempted to remove.
Data has been available for a long time.
If you want to see the homogenisation adjustments to ACORN Stations refer here:
http://www.bom.gov.au/climate/data/acorn-sat/stations/#/23090
Just click on Station List to work your way through all the stations.
You can see the adjustments made and the reasons why. The BOM methodology is also available.
As you can see some adjustments are up and some are down.
If you disagree with the finding feel free to prepare a submission and get it reviewed by suitably qualified scientists. That does not mean Jo Nova.
Good luck.
Cheers.
Seems to be a reasonably lengthy and quite successful history of modelling anthropogenic climate change.
https://www.carbonbrief.org/analysis-how-well-have-climate-models-projec...
I wondered about this for a long time .. I came at it form another point of view: I asked the question: if the models are so technically deficient and the maths so bad how can they be so good?
The answer is they aren't!
There are lots of things that there are no models for but the three biggies are: radiative forcings and clouds and water vapour. The simple answer is we don't have a mathematical model for the three most important factors so guess what .. the modellers just said: we will fudge it .. yes that's what they did ... they literally just invented numbers for forcing, cloud cover and RH and then kept "fudging" these numbers (not mathematical models but just numbers) until the model output agreed with the "observed" historical data (keep in mind what I said about the quality of historical data above!).
And so they fudged lots of important parameters for the models using hind-casting until the models agreed with the historical data and then said oh well we can now trust the models to predict 50 100 years into the future ... BS!!
Remember what I I aid above about what happens to the models if we reduce the resolution (if the model is good should be better outcome ...) but it doesn't the models crash! And that's because the fudging doesn't work when we really test the models!
Here is a technical discussion of forcing used by NASA (the only public model): https://data.giss.nasa.gov/modelforce/
you might not get the tech but the gist is : we FUDGED it!
Similarly and even worse for RH and clouds!
Models are BS and they even proved it: we know a lot about Mars, its a very simple planet: no oceans, no clouds, no water , no mountains, just a simple atmosphere which we know more about than earths: they ran the climate models on simple plain basic Mars and they didn't even get close!
I mentioned the absorption anomaly above: the models predict a certain incident radiation at the surface of the earth and we can measure that: the difference between the observed and predicted [from models] is 25-30Wm^2 .. the WHOLE contribution of CO2 is about 5Wm^2 so the error in the models is 5x the WHOLE CO2 contribution : the models are BS!
They are interesting toys for predicting the weather a few days or weeks ahead but that is all they are useful for UNTIL we get much much better !!
Sorry mate but your assertion they are wrong is not backed up the available evidence.
even allowing for the fact certain important processes may be crudely understood the models are proving useful in their predictive power.
I agree .. for weather a few days ahead they seem to work about 70% of the time ... bit for climate 50 years ... ahh nah!
"if the models are so technically deficient and the maths so bad how can they be so good?"
You haven't even begun to demonstrate this.
Hey I'm wondering Will, do you shape surfboards?
as to the maths you haven't read the above on models
shape ... yes in my spare time .. try to ...
I think it's possible to have a reasonaly informed position on AGM without caring about the efficacy of models one way or another.
No sure what AGM is but it you mean AGW then yes I agree, I just don't see it (and it isn't!) our most urgent problem. I see the following:
1: energy
2: water
3: conflict USA/Russia/China
4: Armageddon viruses/bacteria
5: meteor
6: mega volcano
XX: climate change with an Ice Age being the most feared!
Err yeah...AGW...not an Annual General Meeting, though those things should be feared too.
AGM...........snicker......
sorry Stu, that made me laugh.
That's my last shot at pomposity.

You missed unsustainable population growth in your list Will its without a doubt the number one problem in the world today its the driver behind energy and water issues, deforestation and man made global warming (if one day confirmed) not sure how you deal with it though, its only going to increase and all these problems will get worse.
BTW. That ocean acidity thing is a good read id love to hear the opposing view on it, im only an ordinary guy but it actually made sense.
Makes you super suss when its obvious they are misusing words like acidic obviously to put fear in peoples heads.
Its shocker really, profound statements like the oceans wont become acid, acidification is an inaccurate term then the really heavy hitting term alarmist, got to about the 2nd or 3rd one and thought is was a setup seriously not to mention how good co2 is for everything.
There has been a a fair amount of work done on the issue just like CC the probabilities are there.
My issue with Will is his terms of absolute to narrow points then applying to the total, making tribal politic points then criticising the problems around doing just that not to mention total ignorance about energy.
Sounds more management than research but still welcome the commentary for a quite arvo local breaks close due to to a 3mt GW going fishing 75mt of the beach.
World population has slowed to 1% overall and at current trend will go into negative growth within 20 years. Australia is perfect example: white anglo saxons are not reproducing ourselves: we are dying out and only immigration is causing an increase!. Within a few generations WASPs will be relegated to history ... fuck Darwin ...
Deforestation is a serious issue for the the most important species on earth: the pollinators birds, insects and bats! (no ... algae are the main producers of O2!!)
The acid thing was OK ... there's some errors in it but its OK for starters ... sea water chemistry is actually really really Really REALLY complex: all sorts of stuff being washed in, all the animals, algae, bacteria, rain, pollution, soils, volcanoes ... no one really knows ...

“The tactic of sowing doubt works, because there can be reluctance to change policy or regulation in the face of doubt. But absolute certainty is rare. It does not mean that what we know is wrong.”
......And you win this forum!
Indeed it's an incredibly well oiled machine that sows said doubt. For instance, I listen to a particular radio station daily and it's incredible how good they are at it, they've got this recipe of slipping in the doubt (or an extremely conservative view) in with some other general empathetic or emotive message, it's so slick you barely even know you've been fed it...
You guys sound like religious people after people are questioning their blind faith.
Its far from a scientific approach when you don't take all scientific views on board and keep reassessing what we know, problem as we all know is its no longer about science its about politics and money
If Will was saying renewables suck we need to burn more coal and oil and cut down our forrest etc. then yeah write him off as some climate denier rather than a climate skeptic.
But just like me, it seems he thinks our energy needs moving forward are an important issue and the development of renewables an important thing even if mans influence on climate ends up being minimal or the dooms day scenarios way over cooked we both support things like renewables because well to me it just seems like smart way to create energy.
Just remember end of the day who are the ones believing in in the new generation of lasts day on earth armageddon scenario and how we all look back on those who blindly believed in past last day on earth is coming scenarios.
Energy............what a mess particularly eastern states currently in Australia there isn't a policy, last 25 years of policy turmoil has got us to this point where Victoria is hoping for perfect conditions to keep the lights on, energy prices through the roof, gas sold off then resold to domestic uses higher than export prices.
That's before you get to the political, cultural, right wing nut job, vested interests, disinformation BS affecting renewable's.
The technical and engineering capability exists right now to go to renewable's that's not including hydrogen and diffidently not including Fission..
Instead of a 5, 10, 20 ,30, year plans there is pretty much SFA.
Only area that is true is gas, which agree is a mess, otherwise its just simply not true.
Our main source of energy is coal, why because we have plenty of it and easily accessible it was a simple and common sense to get our energy in this way in the past, however no doubt we will move away from coal fired energy as the lifespans of our power stations end, but no we won't shut down power stations without ability to replace them.
Apart from small black coal plants loy yang was the last big coal fired power plant, built in the 80s so its not like we are building new big coal fired power stations.
Renewables: per capita we have the highest uptake of roof top solar in the world, this has happened because of government federal and state schemes encouraging people to put roof top solar on.
We also already have about 100 wind farms in Australia and a number of commercial solar farms including the one Adani opened just a few months ago in QLD
Studies show at current rates we are on track to over 70% renewables by 2030, if you want to be conservative we could say 50% plus.
In regard to tech its getting better all the time, but still storage is the issue.
For many its about when to pull the trigger, its like buying any new tech based product, if you buy in too early its costly and you end up with old tech, wait a little and prices are cheaper with much better tech, the whole area is so much better then ten years ago though.
Prices are dictated by many factors, but high mains electricity is actually the biggest incentive to people putting on roof top.solar.
and then there were the Germans ....phased out coal , nuclear by 2022 .....how does one explain Australia's energy problems when Germany are....
https://cleantechnica.com/2017/05/08/germany-breaks-solar-record-gets-85...
Silly to compare Australia to other countries, each country has a different history of sources of energy due to resources available etc and at different stages of the life span of their energy sources, so will make transition to renewables at different rates based on things like age of current power plants and economic factors.
BTW. what is this energy problem in Australia?
We have reliable affordable energy, dont know about where you live, but where i live its super rare to get a black out.
Germany is a weird one, their transition to renewables hasn't been smooth sailing, energy prices have risen but emissions not dropping as predicted, mostly because dropping nuclear achieved very little reduction emission wise, they also pay the highest electricity prices in europe.
spoken like a true denier , "Silly to compare Australia to other countries, each country has a different history of sources of energy due to resources available etc and at different stages of the life span of their energy sources, so will make transition to renewables at different rates based on things like age of current power plants and economic factors."
So an industrial Country who polluted their own back yard , used technology to clean it up , went to renewables , shut down their coal industry , is shutting down their nuclear plants ...so nothing to learn here from one of the worlds most stable countries in looking at a cleaner eco future?
It has been announced by the Vic govt that this summer there will be blackouts , to the point where even business's like Coca Cola are quoted as saying Victoria is like a 3rd world country when dealing with the Vic power grid!
How can you say emissions not dropping,link? nuclear is not about emissions , its the byproduct of the reactors and if there is a problem( meltdown) how do you fix it and it will destroy the surrounding area...
So they now have guaranteed electricity...we do not!!
Germany only survives because it buys "dirty" energy from coal and nuclear from other countries: https://www.cleanenergywire.org/factsheets/germanys-dependence-imported-...
As to nuclear: ever heard of Thorium .. look it up .. Sydney uni has one of the most advanced Thorium reactor programs in the world but can't get any funding .. partially because we pour BILLIONS into stupid hand waving virtue signalling feel good crap like "hot rocks" and bats and climate councils and other BS!
Hi Will,
"partially because we pour BILLIONS into stupid hand waving virtue signalling feel good crap"
Globally USD4.8billion is spent DAILY on military expenditure. And what do we get for it?
How good is that!!!
reading your link was educational , as you can see that the biggest problem Germany has with fossil fuels is the transport industry , which Hybrid electric could solve ...
I use Germany as an example because they are really trying to clean up their act and look for more renewable solutions...you just have to look at....
https://www.cleanenergywire.org/factsheets/germanys-energy-consumption-a... you can see how they are trying wean themselves off coal and oil!
Thorium.....ah dare we go down the fossil fuel lobby and work out why they don' want this technology.....??
Brutus Stop misquting me i didn't say emissions aren't dropping, i said not dropping as predicted.
Google the topic.
Edit: related read: first drop in Germany's emissions in 4 years, ironically due to warm weather though
https://www.apnews.com/24711c51433b464e962f162bb92c2b41
Stop being so ignorant, things get replaced as needed, transition to renewables is just that a transition.
You want to see energy problems in Australia ?
Best way to do that is to shut down coal fired power stations before we are ready to to so, achieving virtually nothing to world emissions.
BTW. Im not a denier im a skeptic, a skeptic has an open mind and looks at all aspects of the issue, not like blind religious like believers of dooms day scenarios and their the end is near plaqyad hanging from their necks.
I don't want to shut down coal powered power stations until we have a better system , it's amazing when you look at the USA where coal mining is struggling , as the power stations are now changing quickly to gas from coal...gee wish we had some gas in Australia and didn't have to build a port in Western Port so we can ship our gas in.
I am skeptic also , and take onboard the current state of the planet and believe that there is a strong case to start planning for the worse and hope for the best...it's called an insurance policy for our future ......
The end is near to the lifestyle us baby boomers have lived , we are leaving the planet in a worse condition than when we were born, and the debt we leave our children is a crisis of our making......or do you think that's a good thing?
May be hard to prove at this point in time but wonder if these polar vortex events are associated with climate change.... and what implications are for surf in a few weeks.

Another good read on renewables in Australia
A new report has found that Australia is installing renewables at world-leading pace and is on track to ‘significantly’ exceed the 2020 Renewable Energy Target (RET).
https://arena.gov.au/blog/australian-renewables-growing-at-record-rates/
All this talk about renewables .. its off topic but here's a little factoid Ill just throw in like a grenade ..
Australia could build 3 dams and supply ALL of our water and energy needs for the next century!
Why don't we build the dams
(NB: Australia's 3 World Heritage Listed Parks are ALL built around man made dams: Tasmania; Kosciusko and Blue Mountains!!!)
Here you go Will.
http://www.bom.gov.au/water/dashboards/#/water-storages/summary/state
It might explain things to you.
Explain what .. that there are now 25 million people using dams that were designed and built for 6 million ... didn't need that explained ...
Hi Will,
I’ll translate that for you.
The rain isn’t falling the way in the volumes and locations it used to.
Look at the Murray Darling Basin today. Lack of rain and poor management have created a disaster.
Cheers
I reckon you and I tune into the same radio station
We don't build dams because no matter where they are proposed there is strong opposition.
Waster levels in dams is irrelevant better 20 half full dams than 10 half full dams.
Plus governments often don't plan for long term unless it gets them reelected.
The dams would be up in the tropical north .. they get METRES and METRES of rain .. we can use the rain to fill the dams and then run back out to sea to generate power and even divert some of it to the south ...
But like u say ... no more long term planning in politics ...
This has been discussed many times over the years and has never been found to be viable.
Also, the rain is seasonal and evaporation rates high.
Cheers
If you want to speak to someone who knows better than thousands of the world's top scientists, is more on top of it than all of the world's meteorological and climatological agencies and could single-handedly solve Australia's water and energy issues, just talk to Will.
Might even design a mean wavepool.
Just out of interest did you know that you have never EVER heard a CSIRO or BoM scientist speak about climate! That's because they are specifically BANNED form talking to anyone (the media, forums, social media even family!) .. so when you say "thousands of the world's top scientists, is more on top of it than all of the world's meteorological and climatological agencies" its just more BS!
What you have seen and heard are the PR people and funding spin doctors and political animals .... NOT the scientists!
Mmm, none of that info comes from scientists and their research, it's all made up by PR people.
Speaking of PR, you sound like you're spruiking straight from the IPA handbook.
Really..?
David Jones did a PhD in Earth Sciences and joined the BOM in 2002 as the supervisor of Climate Analysis.
Here's a list of the 15 articles he's written for The Conversation (while working at the Bureau), many of them about climate change: https://theconversation.com/profiles/david-jones-2467/articles
Here's an article written for Fairfax (again, while at the Bureau) titled our 'Hot, dry future' that points the finger at AGW.
He's a puppet for the loonie left Stu, dincha know?
I'm curious how he can get that point so demonstrably wrong.
I said they were banned from TALKING about climate but not from papers because the spin doctors have to PRE APPROVE all public information. So that "article" you are talking about (and others) was authorised and edited by the spin doctors ....
Ask David Jones if he will come on this or any other public forum and TALK or give unscripted and/or unauthorised information to anyone! The reason is that ALL public utterances MUST be authorised by the PR people and MUST toe the political/funding agenda ... the same goes for ANU staff (where the main BoM and CSIRO headquarters are located) who are also banned form any public comment ..... they cant even tell you they are banned form unauthorised public comment ..... you might like to wonder how I know this ???
David spoke at a seminar a few weeks ago:
"Speaking during a Bureau of Meteorology seminar on climate, BOM climatologist David Jones said the drought had now exceeded the Federation Drought, the WWII drought and the Millennium drought in terms of its severity through the Murray Darling Basin (MDB)."
https://www.merimbulanewsweekly.com.au/story/6281486/drought-now-officia...
The BOM website suggests it's an ongoing thing too.
"Representatives from the Bureau of Meteorology are regularly requested to make presentations at industry events and conferences. These are opportunities for us to engage and educate about our role in water information."
http://www.bom.gov.au/water/newEvents/presentations/index.shtml
Plenty of BOM Research Community Seminars here too (with speakers from BOM, CSIRO plus a wide range of overseas educational institutions):
http://www.bom.gov.au/research/research-seminars.shtml
Dams are just opposed full stop by the loonie "fingers in the ears ..no dams .. no dams ... no dams .... can't hear you" NO DAMS brigade!
There has never been a serious assessment of a combined hydro and piped water in the Cape/Gulf area.
As to seasonal ahh yes that's why you have a dam to store water during the rain for periods when its not .... and no this is the tropics .. its humid all year around especially on the Cape and Gulf: evaporation is actually quite low!
As for rainfall the statement above is just BS: rainfall statistics are here:
http://www.bom.gov.au/climate/averages/tables/cw_031011.shtml
And if you go here:
http://www.bom.gov.au/climate/drought/#tabs=Rainfall-tracker
You will see that on average our rainfall for the last few years ...is .... well .... average: more in the West, less in the East and average for most. Track back to the early 1900s thru to 1914/15/ if u want to see a real drought!!
where would you build the dams?
Will, apart from the Wet Tropics south of Cairns, virtually all of Northern Australia sees evaporation exceed rainfall - evaporation is generally between 2000 and 2400mm per year.
I'm beginning to suspect that you're a bit of a bullshit artist.
Oh are u really serious ... have you seen the river flows out to sea in wet season ... hahahaha the fact that you could even make such an assertion is just so far beyond credulous as to be bordering on psychotic delusion .... What you say is the actual geographical definition of "desert" look it up!
Just to see hear and feel Twin Falls or Barron Falls in the wet is staggering for the senses .. and that's just two of hundreds of massive rivers that flow out to sea!
Look on the BOM site mate, the facts are clear, just like the fact that you are a bullshitter.
http://www.bom.gov.au/watl/evaporation/
Oh that’s right, these figures are a plot by those loonie lefties in who are controlled by spin doctors :)
Could not have picked a more perfect example of how people who do not understand science or technology should NOT comment on things they do not understand:
THIS IS NOT ACTUAL EVAPORATION it is THEORETICAL EVAPORATION FROM A PAN OF WATER YOU MORON!
Quote from the top of the page:
These evaporation maps show the amount of water which evaporates from an open pan...
Now stop making a complete fuckwit of yourself!
Yes it’s in a pan and yes this is how evaporation is calculated - these rates ARE used to calculate evaporation from water bodies and they ARE used by farmers to figure out how much water their stock needs.
Regardless that pan is higher than actual evaporation, most places in northern Australia still have a higher evaporation rate than precipitation.
Some deity please give me strength!
I will say this in simple slow words:
A dam takes shallow water from a LARGE SURFACE area e.g. rainfall via rivers, valleys, terrain etc and concentrates it into a deep but SMALL SURFACE area so the THEORETICAL PAN EVAPORATION RATE from said SMALL SURFACE area is IRRELEVANT to a DAM that collects water from a much LARGER SURFACE area!
Simple enough .... do you get it now ....
still really interested in your 3 dams theory that would solve Australia's water and electricity needs for the next 100 years!
Please explain?
Your words, referring to Northern Australia generally - “evaporation is actually quite low!”
I understand the concept behind dams, storage and surface area, I merely pointed out that evaporation in Northern Australia is actually very high as shown by the BOM, regardless whether it’s in a pan or in a water body without metal sides!
And your definition of a desert is bullshit - you are a bullshitter.
You are full of shit.
couldn't agree more..changing peoples opinions, particularly close minded people is one of the hardest challenges around. i wonder if his caps lock button is worn out on his keyboard yet. his arguments are as compelling as malcolm roberts, he could probably get a run with one nation too
By the way, where are these “hundreds of massive rivers” in northern Australia?
You’re on crack.
Just take it easy on the wife and kids.
And the dog.
Will, your original objective was to inform and influence those on this site who are interested enough to vote and make a difference.
The frustration you're feeling in communicating your message may be due to the intransigent nature of your audience, or may be that you need to seriously reflect upon your beliefs and the motivations underlying those beliefs. Personal growth can be hard but I strongly support you taking a period to reflect upon your beliefs and consider whether you may be wrong. And if you're not wrong than you truly are a rare man.
All the best
Will.S = T.Roll extraordinaire.
Undermines the credibility of his own 'balanced' perspective by constantly cooking off at the left, claiming an global government AGW conspiracy supported by the 'science industry' but failing to acknowledge the motivation and complicity of the right and fossil fuel corporations in elevating marginal scientific viewpoints and demanding equal consideration.
Enough: this was about the ability of climate models to predict things like waves and wind and the effect on coasts .. we are way off topic ...
Enough?
You've brought this on yourself. I was generally interested in what you had to say until every second post was polluted with polarising political jibes about virtue signalling, lefties and global conspiracies. How is that limiting the conversation to modelling?
A little 'snowflakey' perchance?
So, you've got an issue with the modelling, but how do you justify supporting an ongoing and entrenched dependency on legacy tech, with known environmental impacts? Or do you consider the wait and see approach as more prudent? This is the bit that I don't understand about denier / sceptics position.
I liked reading your posts will.smithson
Cheers.
ID you were saying power was reliable, this is the situation in Vic for power from an insider
"Looking at the immediate future, Victoria's in a world of pain if the various major problems aren't fixed by the end of the year. With the major failures at Loy Yang A and Mortlake, the extended outage of two units at Somerton, ongoing issues at Yallourn and now a major transmission failure onshore in Victoria cutting all supply between Tasmania and Victoria, it's all rather shaky that's for sure."
Did you know 12% of your power comes from SA, 8% from NSW?
All i know is when i was young black outs were fairly regular and last 25 years or so they are super rare, even if it happens its not for very long, i have no idea how they get the power back on so quick after storms etc but in the 80s it would go off for ages
I think people also have to remember we are in a transition to renewables, considering this we are doing amazing.
Sorry for the positivity, just telling it how i see it, i dont have anything to complain about, even prices imho are good value electricity is so important in our life's it cost us very little
Council rates though, high way robbery for little more than a bin pick up service or the fees charged to dispose crap at the tip is just crazy, i can go and get a trailer of mulch etc. cheaper than i get charged for getting rid of a trailer of stuff.
hmmm......https://www.theage.com.au/environment/climate-change/australia-s-greenho...
So Australia is 1/2 way to meeting it's targets , as our greenhouse emissions are still going up!
Did i read that article correct?
Seems all our onshore emissions are dropping but seems they are including our gas exports as our emissions?
Very weird if that is the case, gas is much cleaner than burning coal, if gas is not provided by us countries could be forced to burn coal instead increasing world emissions, same deal with us exporting quality coal, if we don't export it countries are often forced to burn higher polluting coal.
But hey why look at the bigger picture?
As Blowin has pointed out many times our high immigration rates are also an issue, more people equals higher emissions.
indo-dreaming is upfront...back in Joh's days we had rolling blackouts lasting 2 weeks.
Fri 21st Dec 2018 Central Gold Coast was hit by massive winds / Thunderstorm. tbb watched the dread loom overhead & no more than a good gust & 2 lightning bolts, resulted in a power blackout. Here at Reedy Creek we salvaged some fresh food as our power was returned on Sun Night 23rd Dec. Other central GC towns banking [M1]central East Coast were without until after Xmas. (6 days later)

Qld Rolling Blackouts still roll...apart from here, last xmas blackout was forgotten.
(1980's) 2 weeks (2018-9) 5-6 days.
28th September 2016 a Cat 3 Cyclone strikes South Australia. Naturally knocking down power lines as Cyclones do, resulting in blackouts. Clearly a typical Cyclonic Blackout, so naturally hardly National News! However by the grace of God a miracle happened & SA power was restored within 24hrs. Now that's Big News! Yet Libs swear the whole Country stared down an almighty renewable Doomsday Demon. We Qldurrz will never buy into that...Oops! tbb spoke to soon.

@ Indo, Sorry for the positivity
I admire your positive force shield ID would help if you could run around screaming the sky is falling and get with the program.
With endless coal, gas, wind, sun and arid areas for renewable's with little to no impact the transition should be repetitively easy, hydrogen on the horizon is a no brainier our current fuel reserve is around 26 to 28 days win win for environment and security.
Forget nuclear as we don't / wont have the capability for enrichment of the uranium oxide plus the 20 to 30 year lead time then there is the not in my back yard that's before you work out what to do with the waste.
Sorry i just can't do the sky is falling thing and super sceptical on it all, expect is seriously over cooked and driven more by politics and money.
BUT that said i honestly want to get solar on in the year as just finished a big extension and just makes sense and i drive a small tradie car for low fuel consumption and try to reduce waste where possible even thinking of reducing meat in diet just for health.
So even though im sceptical im not against reducing my carbon foot print but more because i think its a good thing rather than doing it out of fear or thinking its going to make any difference.
