Wibblefish at 22:30 PM on 27 November 2019It's the sun
Reading though the comments, there are mentions of the cooling/warming effects of El Nina/Nino. Looking at this from a marine biologist perspective, I'd like to bring up the effects of climate change on tropical coral, particulary in the indian ocean and south pacific and how examining coral biodiversity records could be used to support AGW. Coral live between a fairly narrow temperature range. Extreme rises in temperature lead to bleaching and usually coincide with el nino events where vast bodies of warmer become trapped in the indian ocean and southern pacific. What we are seeing is a decline in biodiversity and massive bleaching events in the last 30 years, notable events in 1998, 2005 and 2017. Studying in the Maldives, there was evidence of coral recovery but ONLY for a few species compared to what can be found in historical records. Then the whole system got hit again in 2017 so back to square 1. To me, it is apparent that such a delicate ecosystem can be thriving for thousands of years and then hammered by prolonged, frequent, intense el nino events in a short space of time is a smoking gun. The reversal of trade winds seems to hinge on a delicate energetic balance in the atmosphere. I don't know why it's difficult to comprehend that insulating energy would change the dynamics of a system.

I would like to know how this survey of Climate Scientists in the USA , which says that 52% think that human activity is warming the planet, relates with the 97% study. Surely, this is a big difference.

Doug_C at 15:29 PM on 27 November 2019Harnessing gamification to defeat climate misinformation
My experience with climate deniers both directly in my life and others I've met in impersonal formats like online forums is they attach the climate change issue to emotion and personal identity. It is hard to reason with someone when first of all what you are saying causes an emotional reaction, it doesn't stimulate a critical thought process. And secondly when what you are presenting threatens their personal identity.
Something like this would seem to open a back door into the discussion where people stop reacting with emotion and feel like they are being threatened. Instead of a cold analytical description of a complex crisis we have a game designed to allow a much freer flow of accurate information on multiple issues.
Something like this offers multiple benefits as it is effective across a broad spectrum of groups especially younger people. And it will be almost impossible to counter by the climate denial campaign as more and more users become skilled in identifying the denial techniques.
Impressive, I'd say.

One Planet Only Forever at 14:37 PM on 27 November 2019Harnessing gamification to defeat climate misinformation
nigelj,
I share your concern about the repetition of Fictional claims being a significant mechanism for developing and strengthening the popularity of the belief.
Learning critical-thinking to spot misinformation will help, but it requires more of the non-Fiction details to be readily available. It also requires a person to want to seek out the non-fiction and use it to more quickly spot misinformation on an issue.
That desire to expand awareness and improve understanding appears to be lacking in the populations of the supposedly most advanced nations. I even found it lacking among fellow engineers when it came to climate science, even though an engineer can only properly perform their job by expanding awareness and improving understanding and applying critical thinking - no gut reactions allowed.
What I see as a bigger problem is that the general population is not exposed to the Non-Fiction more than the Fictions.
If the Non-Fiction was seen more often it would be harder for the Fictions to stay standing.
Many things probably keep the Non-Fiction from being seen more than the Fiction including:
- the damaging belief by media owners and reporters that they need to present Balance and avoid 'appearing to be biased'. That leads to reluctance to do what needs to be done.
- The social shift towards Quicker: It takes longer to properly present the Non-Fiction.
- The social shift towards Image/Impression rather than Reasoned Substance: An incorrect but passionate gut response can win over a detailed evaluation of the evidence.
- The dominance of Self Interest: It negates concern for Others, especially Others in the future generations.
- The social technological shift to 'not have to see or hear what you don't care to see or hear'.
- The pursuit of status being measured by popularity or profitability. How harmful the pursuit is will be irrelevant if it succeeds, even just regionally, temporarily, on election day.

nigelj at 07:01 AM on 27 November 2019Harnessing gamification to defeat climate misinformation
Imho this critical thinking and teaching awareness of logical fallacies is such important work if we want people, especially young people to be informed and make good decisions. I was lucky enough to stumble across a book on logical fallacies while quite young. It's sad that more people weren't talking about all this in the early years of the climate issue, but better late than never, and it will help with many issues beyond the climate issue.
The denialists are in many cases a core group of professional hired guns with no ethical scruples about what they say. It all radiates from there to member's of the public who repeat what they say, all well documented in books like Dark Money and Merchants of doubt.
However there's another perplexing problem discussed in this article. " Repetition is what makes fake news work, too, as researchers at Central Washington University pointed out in a study way back in 2012 before the term was everywhere. It's also a staple of political propaganda. It's why flacks feed politicians and CEOs sound bites that they can say over and over again. Not to go all Godwin's Law on you, but even Adolf Hitler knew about the technique. "Slogans should be persistently repeated until the very last individual has come to grasp the idea," he wrote in Mein Kampf."
This seems like a difficult problem for people to expose and unwind, because every time we discuss some fake statement it repeats the fake statement. Yet its also important to expose falsehoods or they gain traction. It's a perplexing issue.

michael sweet at 05:40 AM on 27 November 2019Ice age predicted in the 70s
Barry,
As Scaddenp states, your two comments conflate stratospheric ozone and tropospheric ozone. These are two different subjects and treating them as similar suggests that you do not understand atmospheric chemistry.
I will address your comment at 71 on stratospheric ozone first. According to this RealClimate post, the decrease in stratosheric ozone caused by human pollution will result in approximately -.15 w/m2 of cooling. The CFC's released by humans have caused approximately +0.34 w/m2 of heating due to their greenhouse properties. Thus the result of CFC pollution is a net warming of the surface.
The total warming caused by CO2 pollution is much larger (about 1.7 W/m2 in 2011). Larger amounts of CFC pollution would result in more warming, not cooling as you suggest. Dr. Hansen's 1989 projections, especially the high emission pathway, overestimated warming somewhat because the Montreal protocol resulted in CFC emissions being lower than he projected (more emissions mean more heating).
Your comment at 72 addresses tropospheric ozone. Everyone except you knows that ozone is a greenhouse gas. It causes warming when increases in trophospheric ozone occur. Ozone is not even on the table in my reference above. The contribution of CO2 is much greater because CO2 accumulates in the atmosphere over time while ozone is destroyed and does not accumulate.
I stand by my comment that " I have never heard of significant heat being let out." The Realclimate post I linked starts out "One of the most common mistakes that we have observed in discussions of climate and atmospheric change is confusion between the rather separate concepts of ozone depletion and global warming." When I taught High School students often confused climate change and ozone depletion. As Realclimate states, they are different problems, although they are tangentially related.
The original question from post 69 was "They told me when I was at school we were heading steadily for another ice-age and the cause was CFCs". The answer is scientists have never said that CFC's would cause an ice age to occur. The person who asked the question was either misinformed or attempting to mislead others with a false question.

In my final edit of my comment @24, made while re-watching the video, I failed to pick up that the following bullet does not apply.
"And it is further out of bounds to to say that the uncorrected data is “... the chart that the BOM used previously ...”."
That bullet does not apply since the comment was an accurate reference to the chart of adjusted data before the latest adjustments were made. It was one of the few 'correct statements made'.

One Planet Only Forever at 00:40 AM on 27 November 2019Climate Scientist reacts to Donald Trump's climate comments
I drafted this earlier, but then had errands to run, and MA Rogers has provided a great reply.
However, applying the advice of other wise commentators at this site I had a little fun making fun of this. So I am sharing it.
Also, the parts at the end of my original draft (still there) about the guy needing to get a new job leads me to suggest a possible action that could be helpful.
In Canada every business with a broadcasting licence can have complaints about inappropriate content result in regulatory actions from the CRTC, the Licence Governing body. In addition, the Advertising Standards Council acts on complaints about misleading advertising. If similar Institutions exist in Australia, you could submit parallel complaints to the Licence Governing body and the Advertising Standards Council about this specific episode being inappropriate content that is also misleading advertising.
You could also use MA Rogers points to help your friends improve their awareness and understanding by pointing out the many gross errors made by this Guy in this episode.
No Copyright on this comment. Like any comment I make here, it is offered for all to improve, correct, and use as they see fit.
Here are the Key Points presented sort of as they come up during this entertaining, though admittedly annoyingly incorrect, presentation (unlike some entertainment, even vaguely educational, except as a Bad Example). Think of it as similar to a Sportscaster's Play-by-play, or Game Bloopers bit.
The entire game played was a Massive Miss regarding Global Warming evaluation. The global warming trend is best seen in the global average of surface temperature data, not selected local data sets. And that data needs to be reviewed and adjusted for things like changes of conditions at the monitoring locations that affect the temperature measurement at that specific location, including improvements to the monitoring equipment set-up or the local relocation of the monitoring equipment.
The reasons for adjusting the raw data is explained by Australia's BoM here.But let's play along anyway:
- Melbourne is not 'the hot spot of Australia'. And even though Adelaide, or other locations, may be thought of as a similar location, the history of data for Melbourne would be the only relevant data set to review when discussing the hot day in Melbourne (why are other locations like Glen Innes and Lismore near Brisbane not Melbourne, brought up later instead of Melbourne).
- That makes it a clear offside to then leap to talk about data for all of Australia.
- And it is further out of bounds to to say that the uncorrected data is “... the chart that the BOM used previously ...”.
- The guy then attempts to fool the fans by claiming that the previous adjusted data chart, before the more recent better understood and applied correction, indicates more very warm days earlier compared to current years. It actually appears to have more hot days in the recent years, yet he says the opposite, without any explanation. Then he brings up the totally unadjusted data presentation as if it is relevant.
- The item by item descriptions of the 'corrections made to the raw data' are essential. This fiction pitcher dismisses the importance of detailed understanding, because it would shatter the illusion he is trying to create.
Then there is More:
- Another Big Miss in understanding is the importance of presenting how much warmer than 40 C each of the days noted as warmer than 40 C actually was. 40.1 C is incorrectly counted as being the same as 45 C. So, the entire babble about how difficult it is to figure out the number of days warmer than 40 C is another attempt to fool the fans that JoNova happily plays along with. The truth is that such an exercise in an exercise in irrelevance, and someone like JoNova probably knows that.
- Then, on top of the pile of mistakes so far, he makes the massive leap to questioning the legitimacy of a politician who says they understand that global climate change is happening because of the science.
- He then cherry picks 2 location data sets, and makes claims about them, without rigorous proof of the claims (as MA Rogers covers), or any consideration of what may have been regionally going on in Australia's past compared to what was going on globally (like the much warmer than global average 1930s and 1940s in the USA).
- He then makes a Blind Leap of Faith that Fails to Land, by jumping to assertions that unusually cold snowy weather, climate change, cannot be the result of global warming. He appears unaware that the global average has only increased by 1.0 C since the 1800s and that most of that warming was in the Arctic. And an added blindness of his is that the nights are warming ore than the daytime (the minimums that MA Rogers mentions) everywhere. That means that the increase in average daytime highs everywhere other than the Arctic is less than 1.0 C, which questions the legitimacy of the argument that some cherry-picked regional data shows very little sign of increased daytime highs.
- He also fails to compare the frequency of record highs being set vs. record lows being set.
- So, on top of all the other inaccuracies and misleading claims, the evaluation should be done on the average of day and night temperatures, not the maximum day temperature.
His presentation shoots and missed on so many counts. So much Missing. Someone should be 'changing his career' (his team manager needs to do that because this guy appears to be clueless). Maybe a letter could be sent to his bosses questioning his ability to correctly interpret and report information. It appears he lacks the ability to properly Report evidence-based understanding. Maybe Sports would be 'his thing' (sportscasters are the Entertainers of Information Reporters, even more so than Entertainment Reporters).
The Sportscasters might welcome him, but I doubt that. Even a Sportscaster has to get the scores and statistics correct, and know what game they are talking about.
Most important, anyone trying to claim they won based on this guy's reporting would be in serious trouble. Claiming to win of a bet with a friend based on this guy's reporting should seriously affect the friendship, hopefully by the friend having pity and trying to help educate the fooled one. Trying to get paid by a bookie based on this guy's reporting would be worse. Bookies are not interested in Helping Others, and bookies base their actions on a detailed understanding of the facts.

It might also help discussions if you explained why you think ozone depletion reduces stratospheric temperature (or perhaps more to point, why ozone warms the stratosphere).
-
scaddenp at 11:45 AM on 26 November 2019Ice age predicted in the 70s
Ozone is a powerful greenhouse gas in the troposphere.
However, your paper was on stratospheric cooling and looking at the effect of stratospheric ozone. It did not seem pertinent in any way to Michael sweet point. ie the wierd idea that hole in ozone layer was going to cool the earth. I am asking what you think the relevance of your quoted paper on stratospheric cooling is to this question. The ozone in the stratosphere is generated by UV interactions in the stratosphere. It is not a pollutant coming up from the troposphere.

scaddamp,
It is often quoted that many gases such as carbon dioxide , methane and water heat up the eath by allowing visible light to enter and block the infrared radiation coming out.
Amongst these gases ozone is often included for it too is purportedly acting in a similar way.
Are you therefore suggesting that Ozone in the troposphere does not have such an effect? I think the Climate Kids would dissagree with you.
"Close to the ground, ozone acts as a greenhouse gas and can be formed by burning gas in cars and factories" Re The climate kids!

Barry, how do you understand stratographic cooling affecting surface climate? Note that one the big fingerprints for GHG warming is surface warming but stratispheric cooling. However, changes in ozone muddy the picture so detecting the GHG effect means separating this from O3 changes.

MA Rodger at 06:17 AM on 26 November 2019Climate Scientist reacts to Donald Trump's climate comments
prove we are smart @21,
The muppet in the video simply combines a number of weak or falacious argument to support his grand "there is no AGW" delusion.
The first bit of it is feeding off this weblog at denialist site http://joannenova.com.au. There are genuine reasons for adjusting temperature data but the usual nonsense from denialists is that such adjustments are fake, or at least they are fake when the raw data is more favourble to their delusions.
The Mayor of Glen Innes featured in the denialist video says nothing about what data is used to establish AGW. I'm sure if the number of +40ºC daily maximums was how to measure AGW, we would have debunked that particular denialist argument many times before.
The Glen Innes Annual Max data for the period 1907-2012 doesn't show any significant warming trend, although when combined with the Annual Min data, the Annual Average data 1907-2012 does. And over the period 1975-2012 the Average data is running at +0.15ºC/decade although the noise reduces the statistical significance (+/- 0.12ºC/decade at 2sd). The Annual Max also shows a reasonable warming trend but the noise makes it statistically insignificant at 2sd +0.12ºC(+/-0.21)/decade.
And the various reports of cold winters are not incompatible with AGW although it is wise not to listen to other swivel-eyed climate deniers unless you are happy broadcasting fake news. So the blather about a cold winter ahead for the UK is nought but blather. "Claims that the UK is set to face the chillest winter in a century and even a white Christmas have been dismissed by the Met Office."
And arguing against a swivel-eyed loon in full flow isn't for the faint hearted. Unless you have history with the guy, or you can succinctly debunk his nonsense, I would suggest you let this Rowan Dean make a fool of himself. He appears not to always be careful with what he spouts. For instance, I see last year that he proclaimed that "A growing number of scientists now believe solar activity is the real culprit behind so-called climate change." This is the sort of nosense that can be addressed assertively. "A growing number of scientists"? What are their names? Put up or shut up!!

I always enjoy reading your replies Nigelj and One Planet Only Forever, we never stop learning and no-one knows everything..Thats not a criticism. I had a quick look at Australian Sustainable Goals, at some projects..
https://sdgs.org.au/projects/
I guess mostly positive stuff there but the Glencore " ad " of rehabilitating of 1000+ hectare of mining land and also doing this..
On 6 March 2019, it was revealed by The Guardian Australia that Glencore, aided by consulting firm CT Group, had engaged in a large-scale, globally coordinated lobbying campaign to promote coal use "by undermining environmental activists, influencing politicians and spreading sophisticated pro-coal messaging on social media."[93] The campaign was started in 2017 and ran until 2019, when it was shut down in February, according to Glencore.[93]
certainly brought out the cynic in me about the tenth largest company in the world..

I agree it would be counter-productive to argue about the specifics of climate change impacts. The Fiction writers and Fans will see any discussion as a basis for claiming that nothing is certain enough to require serious corrective action "by Them".
However, my mind was putting together the extremely high winds and dry conditions in California that combined to start more than one fire, last year and this year, by blowing down power lines. That seems to be new fire-starting behaviour due to the change of climate in California.

OPOF @4
"Climate Change may be causing changes of conditions that make it 'easier' for the 'Fire-starters' you mention to actually start a fire".
I did wonder about that, and its technically correct, but surely it's of little consequence and so it means the article detracts from the most important facts about climate change causing larger areas to burn . The warming we have seen so far seems unlikely that it would cause many more fires to start. The temperatures and moisture levels in the fire season are very different to winter enough to make a significant difference.
It's a similar issue as to whether climate change causes a particular weather event. It does sometimes but its a difficult thing to prove and it distracts from the key fact that climate change causes more intense or frequent events, and this is easier to substantiate.
Yes maybe its not the main point, but it just annoys me. I also wouldn't underestimate how much climategate pushed things backwards even although it was about specific denialist talking points. But I agree we need a more general philosophical awareness raising circuit breaker so people can see through all the smoke and haze. Pun not intended.

nigelj @1,
Climate Change may be causing changes of conditions that make it 'easier' for the 'Fire-starters' you mention to actually start a fire, as well as making the resulting fire spread quicker and do more damage.
If that is the case then Climate Change does 'cause' forest fires that would not have started without the change of climate, or causes a more damaging fire to occur.
The people fighting to resist the required corrections of the global economy, and the resulting corrections of perceptions of prosperity and superiority, will create harmful misleading Fictions no matter how the expanded awareness and improving understanding is presented (they will harmfully fight their losing battle against improved awareness and understanding to the bitter end).
The key is getting the expanded awareness and improved understanding presented more than all of the many Fictions that are created to try to fight against it. Being confronted with the Non-Fiction often enough should cause many people to Correct their Understanding and stop believing the Fictions. They should also stop supporting or excusing the Fairy Tale Tellers and their remaining Believers.
Once expanded awareness and improved understanding causes a person to stop believing the Fiction, they become immune to being tempted to re-Believe.
And that will lead to a tipping-point that needs to be reached - the point when the harmfully correction resistant all end up Governed and Limited against their Wishes.

JWRebel at 08:49 AM on 24 November 20192019 SkS Weekly Climate Change & Global Warming News Roundup #47
What nobody wants to acknowledge in calculating the "costs", is that beyond certain tipping points, we may no longer have the wherewithal to put our energy supply on a more permanent basis. Even if there were no CO² problem, fossil fuels will run out and we need a more sustainable basis for energy supply, so little is lost by investing in it earlier.
How likely are we to engage in negative CO² emissions without stable renewable sources of energy?
We should be diverting all global military spending to making progress on this front, since it is an inevitable obstacle, even absent climate change.

The Guardian article is their usual good quality, except this could have been worded better: "You can tell because there’s half as much ice in the Arctic, and because forests catch fire with heartbreaking regularity and because we see record deluge. " Climate change isn't causing forest fires, thats caused by lightening strikes, arson and felling forests whether legal or illegal. Climate change just makes for hotter and drier conditions and possibly more intense winds that lead to larger than normal areas being burned.
Don't give the denialists such easy mistakes and targets to attack.

James Charles,
The issue with the ozone hole is that harmful UV radiation is allowed in. I have never heard of significant heat being let out.
If "they told me at school" was that college, high school or elementary school? Was it in a Science class or an English class? It is unlikely that it was college. Grade school teachers are not really atmospheric experts. Do we rely on experts or grade school teachers?

Thanks, MA Rodger. It was mysterious to me, where he ( Jkss97 ) had gotten the 4500ppm figure from. As you say, a future 4500ppm level would require the decomposition of vast amounts of carbonate rock, or maybe some other almost unimaginable cataclysmic event.
And yet if he had meant to type 450ppm, then this figure is easily achievable by mankind continuing "business as usual" ~ and probably will be reached in a few decades' time.
But with so many typo errors (and scientific errors) in his post #804 , there was a great deal of uncertainty about what he was on about. ( I gave a marking of nine errors there . . . though a stricter assessment might have scored thirteen errors, not counting the 4500 and the scientific errors).
It is less than 24 hours [now] so it is just possible that #804 might not be a room-temperature-level typical "drive-by" comment: and Jkss97 may return and explain what he means.
My other thought was of some translational difficulties perhaps ~ but then again, a non-native English speaker would likely be too careful in his typing to make such a large number of typographical errors . . . and also, the peculiar grocers' plural - volcano's - is an error unlikely to be made by a foreign learner of English.
We shall see.

MA Rodger at 00:22 AM on 23 November 2019Climate's changed before
Eclectic @805,
I think the reason for the 4,500ppm is probably that such levels of atmospheric CO2 have been found in studies for the early Phanerozoic, indeed perhaps higher. And if all the fossil fuels were burnt [they reckon coal reserves are perhaps 1,000Gt(C) with oil & gas perhaps another 500Gt(C)] you'd 'only' raise CO2 by some 350ppm with perhaps natural feedbacks adding as much again. So mankind would be hard pressed to 'achieve' a 4,500ppm level of CO2 by fossil-fuel-use alone.

Its a matter of history that as global tempatures rise evaporation increases and so dose plant matter that ends up traping it in soil or algea or bactria humans are a small pawn in this game. they only real major contributor to co2 is volcano's there is no way humans will ever elvate co2 levels to 4500 ppm

The only sustainable economic benefit is the new sustainable economic activity that has to be developed consistent with achieving and improving on the Sustainable Development Goals.
And the more rapidly the corrections of economic activity are developed the better it will be for everyone, except the people who want to continue to get away with harmfully benefiting from fossil fuel use.

One Planet Only Forever at 14:40 PM on 22 November 2019New report finds costs of climate change impacts often underestimated
Actions to 'adapt to climate change' will distract Leadership from, and direct wealth and effort away from, acting to sustainably improve the lives of the less fortunate.
And failing to limit the climate change impacts, by failing to rapidly end the use of fossil fuels, makes it harder to maintain any developed perceptions of reduced poverty that have been developed to date. And since fossil fuels are non-renewable, any perceptions of reduced poverty 'because of fossil fuel use' will not be sustainable.
And how does humanity 'build an adaptation' to climate impact losses of robust diversity of life in the Seas, Lakes, Rivers, or on Land?

I await a thoughtful explanation of what is wrong with the content of this post on this website that this comment is made on "to help develop sustainable improvements for humanity".

nigelj at 11:41 AM on 22 November 2019New report finds costs of climate change impacts often underestimated
William is right mitigating climate change could be a huge economic stimulus, but I would say in the short to medium term while infrastructure is being built at a heightened pace. In the longer term climate change will degrade gdp growth or at least what growth could be achieved.
But remember a climate related infrastructure programme will tend to borrow resources form other parts of the economy, so its a little bit of a zero sum game, but not entirely - because a big infrastructure build will promote innovation, new mineral discoveries, and some greater efficiencies. This would certainly add up and increase total economic output and it would help profitability and employment.
A good analogy is the wartime economy during WW2 where gdp growth and productivity growth improved, and unemployment fell dramatically, although some of this was bounce back from the economic depression of the 1930's. All easily googled.
But the other interesting thing is inflation and interest rates are is quite low right now, and there is a surplus of global capital, so its an ideal time for enhanced infrastructure building. Many media articles have discussed this in relation to the general economy.

On the other hand, climate change could provide a huge economic stumulus. A bit like an arms manufacturer. They have to have someone expending ammo and the faster the better. Then they keep raking in profits. Imagine the stimulus of all the buildings on Manhatten Island being flooded and rendered useless. You have to tear them down, rebuild them somewhere else, turn the island into a park. Jobs created without end and velocity in the economy accelerated (speed with which money circulates)

nigelj at 06:18 AM on 22 November 2019Here Are 3 Climategate Myths That Have Not Aged Well
Climategate has been investigated to death and the people concerned have been cleared of any form of scientific fraud. I must admit after first reading about climate gate I was immediately suspicious of the claims of wrong doing, because the idea of some climate conspiracy to fake data etc seems too far fetched to be plausible, so I had a closer look at a few articles and it was obvious the denialists took things out of context , and were being misleading. However I already knew about the hide the decline terminology, and anyone not already knowing this term would be justified in being a bit suspicious, and possibly saw the explanations as an ad hoc attempt to make excuses, even although they are robust explanations. The whole leak was damn rotten luck for the mainstream science community, but climate change has marched on and helped vindicate the scientists involved.
The thing is why would denialists be less than honest? It seems to me people are sometimes less than honest when they feel threatened in some way. For example whether it be they are afraid of having to change their lifestyle, give up things they like, pay money, or if their politics and world view feels threatened, or they feel caught out in some way, or are forced to admit to themselves they were sucked in by something ( a lot of denialists probably feel this way). Lots of reasons = lots of denialism.

invicta at 21:06 PM on 21 November 2019Here Are 3 Climategate Myths That Have Not Aged Well
Not long after the email hack that became Climategate I had a discussion about global warming with my brother a self confessed petrolhead and realised I knew nothing about the subject. I went online and did some basic research and the subject of Climategate came up. It took me less than 45 minutes from logging on to realise that one side of the argument was being far from honest. I have no scientific knowledge beyond O level physics 50+ years ago but I could identify a liar when I saw one.
This lead me to various sites but SS in particular and with the help of John Cook, Dana and the many other brilliant people on the site I was able to become that boring old uncle always banging on about climate change, except I was the one telling my nieces nephews grandchildren etc to wake up.
The big thing I learnt from Climategate and subsequent research is that you have to be wilfully ignorant to be a climate contrarian. (perhaps coupled with a little mendacity).

Climate-gate and Clinton-gate also have a similar and sinister look when viewed from the perspective of the pursuit of expanding awareness and improving understanding of what is really going on and the application of that learning to develop sustainable improvements for the future of humanity (achieving and improving on all of the Sustainable Development Goals).
From that perspective both -gates appear to be harmfully successful misleading efforts by people with powerful interests that are understandably contrary to a sustainable improving future for humanity. Many powerful people today still support efforts to prolong the misunderstanding of Climate-gate without suffering any negative personal consequence. And they can maintain support for their ability to benefit more from fossil fuel use through other misleading marketing without penalty.
And, from that perspective, it also becomes clearer that harmful misleading powerful people also try to punish or threaten anyone who develops, or discovers and exposes, information that the general population really should be more aware of. Think of how people are sought out and persecuted for exposing truths that harm Private Interests, including hard to justify National Leadership Actions that are hoped to be kept Private or Misunderstood. Compare that to the efforts to find and punish the Climate-gate misleaders who have undeniably harmed the future of humanity.
From that perspective "Russia" becomes an inaccurate term of reference. Many people in Russia, potentially the majority, are not the problem. And "Right-Wing" is also an inaccurate term of reference. Many people with Right-wing beliefs, but potentially not the majority, are not the problem (same goes for religious people).
The appropriate reference is to 'the global collective of people who have developed powerful interests that are harmfully contrary to the development of a sustainable and sustainably improving future for humanity'.
Every nation and every political classification (including religions), has people in it who are part of that harmfully self-interested collective. However, within each identifiable group there are significant differences in levels of acceptance of harmful actions, actions that are contrary to expanded awareness and improving understanding of the corrections and new directions of development that are required to develop a sustainable improving future for humanity.
Identifying the people who are promoting harmful misunderstanding is what is important. And it is important to know that they can be trying to hide inside any identifiable group or nation. The hard part is helping groups (like Nations, Political factions, Religions) realize that they have been compromising their Brand Identity by allowing themselves to be misled, and that any perceptions of superiority relative to others that are developed that way are unsustainable.
Tragically, many people do not care very much about the future. They myopically have faith in their ability to maintain their beliefs. The most damaging people get angry when their developed beliefs and deceptions become indefensible. They fight harder to not be corrected, including making-up things like Climate-gate and Clinton-gate.

The discount rate its use for the climate problem needs considerable scepticism. A high discount rate assumes most of the problem can be solved easily enough with adaptation, which is a very high risk premise A low discount rate makes more sense.
The purpose of the discount rate appears to be to put an ideal price on carbon when what we should be doing is putting 'a' price on carbon that the market can bear, so a moderate price, and then ramping this up as quickly as we can to reduce use of fossil fuels to zero, commensurate without causing massive inflation within the economy. There is no acceptable level of continued fossil fuel use.

nigelj at 08:21 AM on 21 November 2019New report finds costs of climate change impacts often underestimated
Economists like Nordhaus obviously do some useful work, but they make themselves look stupid with their work on climate change. I'm not an economist, but I had most of these problems with the typical economic models figured out years ago, and have mentioned most of them on this website, as do others like OPOF.
It's not that hard, so it makes me wonder what head space economists are in, and whether their personal interests and investments, and their obession with economic growth has introduced a bias into their work. For example its patently obvious that a warmer world must degrade economic growth because the problems climate change introduce outweigh the benefits and economic growth is a function of many things including the climate.
Apart fom that, economists who think 3% economic growth can continue forever are deluded because this growth is based on mineral reserves that are being depleted fast to the point where extraction costs will become more expensive longer term, and theres no way of changing that. To think otherwise is magical thinking.
Rates of economic growth has been on a declining trend in developed countries ever since the 1970's to 2019, despite massive attempts to boost this with tax cuts and money printing, and so its absurd to think we can boost these rates or maintain them indefinitely. All signs are that this downward trajectory will continue in developed countries. No doubt growth will continue or might increase a bit medium term in developing countries, but growth will follow the downward trajectory of wealthy countries eventually. Economists need to get real.
Economists need some proper worst case scenario models, and fast.

Regarding economic analysis getting it wrong because of: "...questionable assumptions about continued economic growth, and from an inability to account for non-monetized values."
The reason that the economic models are failing to get it right is most likely because the powerful people with unsustainable developed perceptions of status have the ability to powerfully fight against 'the understanding of sustainability' becoming the expanded awareness and improved understanding of economics.
Given that humanity should expect to be able to inhabit this amazing planet for about 1 billion more years, with some naturally occurring challenges through that time, it is easy to understand that unsustainable human activity cannot be continued.
And given that a sustainable and improvable future for humans will require a robust diversity of humans to be fitting into a robust diversity of life, it is understandable that any actions compromising the robust diversity of life cannot be priced. The robust diversity of life is Invaluable.
Continued economic growth can then be understood to only be possible through the continuation of Truly Sustainable Economic Activity and the replacement of developed activity that is unsustainable with Truly Sustainable Economic Activity.
Sustainable Growth is understandably only achieved through effective governing of human activity to ensure that the focus is on developing Improved Sustainable Economic Activity.
The current system of allowing unsustainable activities to compete for popularity and profitability then, understandably, has no future. Unsustainable actions are almost guaranteed to be Cheaper, Quicker, and Easier. So a system that allows those types of activities to compete will almost certainly be a declining cycle of unsustainable activity especially if misleading marketing is allowed. And it can be understood that in addition to developing unsustainable activities, such a fatally flawed system will develop powerful resistance to the correction of those activities because of the desires of people to maintain developed perceptions of status and prosperity.
One of the most insidious aspects of the current reality is that developed perceptions of reduction of poverty are potentially unsustainable. That will be especially true if undeserving Winners get to keep their undeserved Winnings as the unsustainable reality becomes more obvious, harder to ignore or dismiss. And the slower the corrections are today, the more challenging it will be for the required corrections of economic activity to be built out of the crumbling ruins of a massively unsustainable developed global economy and its resulting increased negative future impacts.
The solution is the achievement and improvement of the Sustainable Development Goals, all of them, the sooner the better, especially (but not exclusively) the Climate Action Goals. Admittedly that may require many current day Winners to become Losers. But many of them will remain the wealthiest after their deserved loses, if they sustainably deserve it.

The parallels between the Climategate e-mails and the Clintongate e-mails in 2016, from Russian Intelligence via Wikileaks, is spooky.
- Both hacks originated in Russia.
- Both released the e-mails at key moments: The run up to an international conference, the run-up to an election, while the favoured Russian candidate was struggling with a "locker-room talk" sex scandal.
- Both strangely well co-ordinated with right-wing media, who leaped on the stories gleefully.
- Both trapped the "good" media into a fake story that turned out to be a ball of smoke e.g. the DNC e-mails contained nothing negative about Clinton's campaign, the "Climategate" e-mails were minor blemishes.
Coincidence?
No smoking gun, of course, but if the truth is ever allowed to emerge, it will be a strange and mysterious story.

MA Rodger at 23:31 PM on 20 November 2019Increasing CO2 has little to no effect
Dukester @380,
My back of fag packet calculation puts the energy used by shipping at roughly (300Mt/year x 43 GJ/t / (8766 x 3600) = 400 GW. That is certainly billions of kWh/year. But as a global forcing it comes to 400e9W / 510e14m = 0.0008Wm^-2. As of last year NOAA AGGI puts the forcing from CO2 at 2.044Wm^-2 with a total positive GHG forcing of 3.1Wm^-2. Burning fossil fuels does result in much energy release but, depending on the fuel, the resulting increase in atmospheric CO2 will be heating the planet by the same amount over the following 9 to 18 months, and again for following periods of that length. The combustion energy release thus quickly becomes a trivial value relative to the GHG forcing.

Dukester at 11:38 AM on 20 November 2019Increasing CO2 has little to no effect
Firstly let me say how much I have enjoyed reading this topic, oh and I had better add I have no doubt that mans activity is warming the planet, but I am a little at odds with the how....
I must confess that I am more than a little surprised that in everything I have read there is no mention of the heat component thats mans activity is adding to global warming?
I we take the ocean for instance a throw a few thousand ships in it pouring billions of Kw of heat in to the ocean for say the last 70 odd years, and more than 1 or 2 reactors in subs spewing heat in to the oceans. The ocean is not infinite, so all of this hot water must go somewhere, right?. Where are the calculations that determine what percent of the oceans warming is by the heat released by mans "industry"?
And again if we take the worlds population and distribute it evenly over the globe for the sake of back of the napkin math, tabulate the daily fuel burn, heat released by reactors, exothermic process in industry, heat released by electrical appliances driven by wind and hydro, (some fair guesses can be made here) and apply it to our 1 square km model. Throw a bit more water vapor in to the atmosphere, as after we are burning fossile fuels, stand a coloum of air on the top of this heat source about the dimensions of the atmosphere with a large heatsink at the other end and you come up with some really interesting numbers. Certainly they are big enough to be, well not nothing.....
My back of the napkin math suggests that the heat being produced by mans industry at the very least needs to be incorporated in to any greenhouse model, and the sun is not the only significant source of heat. I suspect that greenhouse gases are not nearly as efficient at trapping heat as we give them credit for and the petawatts of heat being liberated in to the atmosphere by man are a much bigger part of the "full" picture, especially when the wavelength of wate heat is considered....
Is it just me or has this work been done already? Or am I simply wrong?

One Planet Only Forever at 07:22 AM on 20 November 2019Here Are 3 Climategate Myths That Have Not Aged Well
Questions regarding Dr. Roy Spencer include:
- "Why is he still able to be perceived to be a pursuer and professor of expanded awareness and improved understanding?"
- "How is he able to still have his work funded, given the history of misunderstanding he has presented, including the many misleading presentations of the results of his manipulations of satellite data?"
It appears that the developed socioeconomic-political systems have become so corrupted by selfish pursuit of personal interest that Popularity and Profitability have been able to get significant control over "The direction of Thought". And that harmful selfishness is able to drive Thinking away from the pursuit of expanded awareness and understanding and the development of sustainable improvements for the benefit of the future of humanity.

Roy Spencer is in charge of a group doing upper atmosphere temperature analysis. If his group were the only group doing this there would be a good case to discontinue his funding, given the misleading comments, sour grapes comments, and straw men he comes out with in the quotes mentioned @comment 3. Anyway his comments are also completely unscientific.
