From Wikipedia: "Mid 2019 plans of CLINTEL and Berkhout were leaked showing that they were organizing a campaign against political commitments to net zero carbon emissions being made to law. The campaign features a number of academics and industry figures with ties to climate change denial groups, as well as members from oil and gas companies" I'll just let this stand for itself...
As climate scientist William Briggs observes: “Global warming alarmism is big business. On one side you have Greenpeace, the Sierra Club, The Nature Conservancy, World Wildlife Fund, Environmental Defense Fund, The Climate Project and dozens upon dozens of other non-governmental organizations who solicit hundreds of millions from private donors and from government, and who in turn award lucrative grants to further their agenda.
“You also have the Environmental Protection Agency, the National Science Foundation, the National Institute of Health, the Departments of Commerce and Agriculture, both Houses of Congress and many more government agencies, spraying global warming money at anything that moves and at staggering rates — billions of dollars.”
There are also innumerable “green technology” companies, from solar and wind energy manufacturers, to battery makers and electric car companies, to lithium miners and biofuel farmers, that benefit handsomely from climate alarmism, and donate freely to the groups that will advance their marketing shtick. There is arguably more money in green alarmism than there is in skepticism.
It took me a while to realize the conceit of this post. I took it seriously because you are absolutely right that there is money on both sides. The difference between the camps is that one has data supporting their argument while the other does not. Climate denial is supported by money and ignorance. Climate science is supported by a big grassroots efforts both by citizens and scientists AND the data. I hope in the long run this camp wins out because I would like my grandchildren to have a shot at correcting my generations mistakes.
Here's Phil Plait tearing William Briggs apart [1]. If you can call him an authority on climate science, I can call the Bad Astronomer an authority on science discussion.
You use terms like climate denial and climate science as if they mean something. You also simply state that we are right and they are wrong as well as give an emphasized hint that the data supports your claims.
If you read what these people (and many others with them) say you'd see that they also claim their position is staved by the data. They call for an opportunity to discuss these matters in public, without being shunned in the way you just did. If their ideas are as faulty as you seem to think they are your side would have nothing to lose by going into this discussion.
This rhetoric is part of what makes the 'climate change' movement look like a religion. Blind discipline, a statement of fact which can not be discussed, shunning of those who dare to differ, making a clear us versus them distinction with terms like climate science versus climate denial. You can even buy off you sins by paying for climate compensation.
Yes, the climate is changing as it has been doing for as long as there is a climate. Human activity has influence over the climate in many ways ranging from soot deposits on snow and ice fields (which warms them up) through local warming by direct emission to the emission of IR-active gases like CO₂ and CH₄. The role of CO₂ is disputable, it is not a strong 'greenhouse gas'. CH₄ is a strong greenhouse gas, as is water vapour. Condensed water (in the form of clouds) has the opposite effect by raising the planet's albedo (reflection coefficient). The amount of CO₂ in the atmosphere has risen since the end of the little ice age, partly due to human activity by burning fossil fuels, partly due to the increase in sea water temperature. How much of the rise is due to human activity is unclear, estimates range from 15 ppm (i.e. hardly anything) to nearly everything. The models used by the IPCC are incomplete (as all models are) and the predicted rise in global temperature turned out to be overstated by a large margin.
In 1972 a group of scientists at Brown University decided the science was clear on the fact that (I quote) the present rate of the cooling seems fast enough to bring glacial temperatures in about a century, if continuing as the present pace and sent a letter to then-president Nixon to warn him of the consequences of a global deterioration of climate, by order of magnitude larger than any hitherto experienced by civilized mankind. They were right in that a new ice will come but they were not correct in their estimate on when that would happen - Nixon did not have much to worry over in that respect.
There was no global public internet in 1972, there were no social media, there was no opportunity for celebrities to signal their social engagement and virtue by standing up and proclaiming that the time had come for all good men and women to act now or risk freezing in the impeding global climate catastrophe. The ice age scare largely was confined to a group of scientists with a few articles popping up here and there about increasing glacial masses and early winter snows. Had there been a global public internet in the early 70's and had Joan Baez, Sly and the Family Stone, Jimi Hendrix, Crosby, Stills, Nash and Young, Joni Mitchell and all the others spoken up... who knows what this would have led to. Imagine a second Woodstock 'for the climate', the public chanting 'no snow no snow no snow' instead of their previous rain-obverse incantation. Just imagine.
Also, don't treat this subject like a religion. It isn't. It is an important subject which should be subjected to all the rigours of the scientific method. That method does not tolerate dogma nor the shunning of differing voices. It is the observation which disproves your hypothesis you want to look for, not the opposite.
It's not a religion. We not only have data we also have the visceral reactions when confronted with real-world examples of what climate change is doing right now.
I was a bit shocked when I heard that the Greenland glacier is melting from the bottom. Arctic waters are feeding energy under it. It is melting at a higher rate than ever recorded before [1].
Here's a fun fact. Last 5 years are the hottest on record [2].
Tuvalu is sinking [3].
This isn't theoretical anymore. The change is coming, fast.
Glaciers always melt from the bottom (or at least appear to do so) since that is where the water goes. Parts of Greenland's glaciers are actually growing [1].
Here's a strange fact: the last 5 years are only the hottest on record when compared to recent historical temperature data. Compared to previous historical temperature data (over the same period) the last 5 years are comparable to but not as extreme as the hot period in the mid-30's. This discrepancy started when meteorological institutions in parts of the world started 'correcting' their historical temperature records. The claimed reason for these corrections - which lower past temperatures while raising recent ones - is that they are necessary to make historical measurements comparable to recent and current ones. This claim has been tested and found wanting in the case of the Dutch meteorological office, KNMI [2 (in Dutch)]. NOAA in the US does the same type of corrections which are being criticised for being excessive but I have not yet found an impartial and detailed report laying out where exactly they went wrong.
In the 70s, the scientific consensus was global warming, not cooling.
>Yes, the climate is changing as it has been doing for as long as there is a climate
This is irrelevant for the current trend
> The role of CO₂ is disputable,
I suppose you have data to back this claim, isn't?
> The models used by the IPCC are incomplete (as all models are) and the predicted rise in global temperature turned out to be overstated by a large margin.
I suppose you have data to support this claim, isn't?
> In the 70s, the scientific consensus was global warming, not cooling.
Consensus is irrelevant here, in the 1800s the consensus was that radiation travelled through the aether. This did not make it true even though it was the consensus.
> This is irrelevant for the current trend
Of course it is relevant for the current trend, it is those historical events which can be used to check climate models. This goes for both recent history (where direct measurements exist) as well as ancient history (where measurements need to be derived indirectly).
> I suppose you have data to back this claim, isn't?
Why, yes, there are many examples. There are many articles pointing out that CO₂ concentration seems to lag behind temperature changes instead of the other way around:
[1] "Temperature and atmospheric carbon dioxide are significantly correlated over the past thirty years. Changes in carbon dioxide content lag those in temperature by five months."
[2] "High-resolution records from Antarctic ice cores show that carbon dioxide concentrations increased by 80 to 100 parts per million by volume 600 ± 400 years after the warming of the last three deglaciations."
[3] "The lag was calculated for which the correlation coefficient of the CO2 record and the corresponding temperatures values reached a maximum. The simulation yields a lag of (1200 ± 700) yr."
[4] "The start of the CO2 increase thus lagged the start of the [temperature] increase by 800 ± 600 years."
[5] "Over the full 420 ka of the Vostok record, CO2 variations lag behind atmospheric temperature changes in the Southern Hemisphere by 1.3±1.0 ka"
[6] "The sequence of events during Termination III suggests that the CO2 increase lagged Antarctic deglacial warming by 800 ± 200 years and preceded the Northern Hemisphere deglaciation."
More on the 'greenhouse potential (GWP)' of CO₂ (and other IR-active gases like CH₄ and N₂O) in "Analyses of IPCC’s Warming Calculation Results" [7] et al.
As to the overestimation of the temperature increase all it takes is a look at the average temperature development versus the predicted temperatures to see the discrepancy. Some articles detailing this discrepancy:
[8] "Actual temperature measurements of 1958-2017 from three weather balloon datasets were compared to all 102 model runs. ... The mid-tropospheric warming trends in the models are caused by increasing water vapour in response to rising CO₂ levels due to flawed moist convection thermodynamic parametrization. Correcting the parametrization to match the temperature and water vapour amounts would greatly reduce the model’s climate sensitivities by reducing the water vapour feedback net of the smaller lapse rate feedback."
[9] "Why models run hot: results from an irreducibly simple climate model"
There are many more articles which pose questions around the accuracy and/or validity of the models on which the climate catastrophe hypothesis is based.
Consider this through the lens of Young Earth Creationism vs. evolution.
The supporters of YEC claim their position is supported by data.
I think YEC's are flat-out wrong, and the physical evidence is so highly weighted in favor of old-Earth evolution that it's fantastical that they can maintain their position.
YEC's "call for an opportunity to discuss these matters in public, without being shunned". However, their positions have long since been demonstrated to be without basis. What YECs are looking for is fame, and influence, which they get by having a public debate 1) where the premise is that there is an argument, when there isn't, and 2) where people aren't permitted to call out the ridiculousness of their arguments.
You say the efforts of "the 'climate change' movement look like a religion". YECs say that evolution is also a religion.
Supporters of evolution have demonstrated that the YECs arguments are invalid. YECs repeat those arguments to new people, which shows they are not interested in the actual validity of those argument.
>> A persistent argument designed to discredit the field of climate science is that scientists predicted an ice age in the 1970s. So popular in fact that it ranks an impressive #7 in the most cited skeptic arguments. The logic goes that climate scientists got it completely wrong predicting global cooling in the 1970s (it started warming instead). Hence climate science can't be trusted about current global warming predictions. Setting aside the logical flaws of such an ad hominem argument, was there any consensus among 70s climate scientists predicting global cooling? ...
while a study of the scientific consensus in the 1970s shows:
>> in fact, the large majority of climate research in the 1970s predicted the Earth would warm as a consequence of CO2. Rather than climate science predicting cooling, the opposite is the case.
You write "The ice age scare largely was confined to a group of scientists with a few articles popping up here and there". While the evidence is quite the opposite - from the same link:
>> a 1975 Newsweek article The Cooling World that suggested cooling "may portend a drastic decline for food production ... A 1974 Times Magazine article Another Ice Age? painted a similarly bleak picture
It appears that the popular press did more to raise an ice age scare than the peer-reviewed scientific press.
Since you want "the rigours of the scientific method", surely you should apply that rigor to your own statements. Was the consensus of climate models of the 1970s really that of global cooling? Or are you repeating an argument long shown to be wrong?
What is the basis of your understanding of the 1970s climate models? Was it a cherry-picked minority viewpoint selected by climate change denialists more interested in fame and influence than the validity of their arguments?
The comparison between YEC and evolution falls flat on its face because of the actual physical evidence in support of evolution where creationists have to call upon acts of god to support their hypothesis. It was god who put the dinosaur fossils in the soil to test the faith of his flock, it was god who twisted the laws of physics in such as way as to make it possible for cosmic background radiation to appear to show the universe as it looked ~14 billion years ago, etc. This dichotomy does not exist in the debate between the proponents of a climate catastrophe and those who do not hold with this hypothesis. Both sides call upon what they see as evidence for their stance, in this case the evidence mostly consists of models. Those models are both coarse-grained and limited in the factors they take into account. When tested against historical data the models have shown to grossly overstate the warming effect, they also leave out some important factors like cloud cover where a ~2% increase in cloud cover can negate the calculated warming effect so it is definitely a factor which should be included.
Creationists are driven by religion. They may claim that evolution is also a religion but that is just playing with words and has no relation to the stand-off between those who support the climate catastrophe hypothesis and those who don't. In the former case religion was the main driver from the start, in the latter the movement got its start based on scientific studies. The current climate catastrophe hypothesis is not the first, there have been several predecessors. Some of these got some traction - the global cooling scare of the early '70s is one of these - while others languished. The religious undertone only became a factor in the current climate catastrophe hypothesis when it was picked up by mass media, celebrities, politicians and business interests who latched on to some parts of the IPCC reports and ran with it. Where the normal discourse in science, although heated, still remains open for discussion and by necessity for falsification, the non-scientific proponents of the climate catastrophe hypothesis had and have no such qualms. It is from there the claims of '97% of all scientists agree' and 'we only have 10/12/15 years left' arise, is is that group which coined the label 'climate denier'. The involvement of political groups in positions of power has made it a potentially career-limiting (or rather 'funding-limiting' but it comes down to the same thing) proposition to openly go against what is now becoming the dogma of the looming climate catastrophe.
This is not how science works. When a model has been proven to give the wrong results you adjust the model, you don't base policy on it. The models used by the IPCC have shown to overestimate warming by a large degree so they clearly are not showing the whole image. The reasons for the over-estimation can be several, most likely though is that the models don't take a limiting factors into account, cloud cover being a possible candidate. Instead of silencing those who follow the normal scientific method by falsifying a hypothesis these results should be taken into account and weighed for their validity, even when they come from a group which is ideologically opposed to yours.
Climate change is a real thing in the past and present, there is hardly anyone who denies this. Catastrophic climate change is a hypothesis. Anthropogenic catastrophic climate change is another hypothesis. The path from hypothesis to theory goes through attempted falsification, there is no other valid way. When presented with what is claimed to be a successful falsification the reaction should be to test it and when found valid lead to something like "well that is interesting, it looks like we missed something" instead of "go away heretic, we don't need your type around here". The former leads to better science, the latter to Lysenkoism.
My point was to say that your arguments are weak, because they apply equally well to those who defend creationism.
You again write "the global cooling scare of the early '70s is one of these".
As I pointed out, this was primarily a scare in the popular press of the time, while the general consensus in scientific literature was that increased CO2 would lead to global warming.
What you are spreading is, and I quote again, "#7 in the most cited skeptic arguments", and demonstrated to be an invalid argument.
I dont have a strong stance one way or another on the climate debate because I haven't familiarised myself well enough with both sides of the argument.
But your points above speak right past the points in the article I quoted, and as such do nothing to discredit it.
And I find the "conceit" label strange. I can understand if you label it "wrong" or "ignorant", but what renders it conceited?
You act as if the sides are equal if proven wrong. If the climate alarmists are proven wrong but their policies acted on we will have moved beyond the convenience of fossil fuels. We will have made a society for our children that doesn't pollute as much. Even if CO2 is harmless in the sense that it does not warm the atmosphere it and the cofactors with it do cause a lot of health related harms. Smog isn't good for anyone. If the climate deniers are proven wrong we hurt our habitat and our children might not be able to fix our wrongs.
I dont think the proposed policies put forward by the climate movement are benign. Remember the yellow shirt protests in France arose because working class people resented the increased fuel tax which was raised as a way to fight climate change.
The article I quote earlier addresses this point quite well:
"In 1997, the late Maurice Strong, former under-secretary-general of the United Nations, said: “Frankly, we may get to the point where the only way of saving the world will be for industrial civilization to collapse.”
In 1992, he proposed a single global government on environmental grounds: “It is simply not feasible for sovereignty to be exercised unilaterally by individual nation-states, however powerful. It is a principle which will yield only slowly and reluctantly to the imperatives of global environmental co-operation.”
In 2009, he declared his opposition to democracy: “Our concepts of ballot-box democracy may need to be modified to produce strong governments capable of making difficult decisions.”
In 2015, Christina Figueres, former executive secretary of the UN Framework Convention on Climate Change and now the head of a climate action lobby group, said: “This is probably the most difficult task we have ever given ourselves, which is to intentionally transform the economic development model, for the first time in human history.”
In 2016, Ottmar Edenhofer, former co-chair of the UN IPCC working group on Mitigation of Climate Change, said: “One has to free oneself from the illusion that international climate policy is environmental policy. This has almost nothing to do with the environmental policy anymore, with problems such as deforestation or the ozone hole. We redistribute de facto the world’s wealth by climate policy.”
Just a week ago, Saikat Chakrabarti, the chief of staff of Alexandra Ocasio-Cortez, the US politician famous for the Green New Deal that failed to pass Congress, was quoted in a glowing profile by the Washington Post saying: “The interesting thing about the Green New Deal is it wasn’t originally a climate thing at all. Do you guys think of it as a climate thing? Because we really think of it as a how-do-you-change-the-entire-economy thing.” "
As someone who hasn't "familiarised [your]self well enough with both sides of the argument", are you able to tell when quotes are cherry picked and quote mined in order to give a wrong impression about another's viewpoints?
For example, I've watched the "creation vs. evolution" so-called "debate" for about 20 years. I quoted "debate" because there is no debate, only continued raising by creationists of the same long-settled issues. (I speak here of Young Earth Creationists.)
But for someone without the specific training in biology (which, to be honest, is high-school level science often avoided in the US schooling I went to, in order to avoid offense to some religious belief holders), it's hard to tell that the creationist arguments and objections have no support in physical evidence, and that the creationists are often quote mining evolutionists. See http://www.talkorigins.org/faqs/quotes/mine/project.html .
To go back to your first comment, "There is money on both sides of the argument though."
There is also money on both sides of the creationist vs. evolutionist argument. And much more money on the evolutionist side. The US National Institutes of Health, to modify your quote, "sprays evolution money at anything that moves and at staggering rates — billions of dollars". Similarly, there are innumerable evolutionist companies which benefit handsomely from evolution.
But that spray, and those economic benefits, cannot be interpreted as support for Young Earth Creationism.
Since those arguments do not work for Young Earth Creationism, they are weak arguments at best, so cannot be a solid basis or proxy for understanding the issues related to global warming and climate change.
The other side argues that climate alarmists are often backed by organizations whose funding depends on the existence of a climate catastrophe. Without a looming catastrophe there would be less public funding and far fewer donations.
From personal observation only, the climate denial side seems to have fewer scientist in all, with less direct relationship to climate science on average, a more direct and pressing connection to their corresponding sources of bias, and with a greater proportion of those scientists who have that connection - and all those faults in a great majority. So, from my point of view, it doesn't seem like a draw when it comes to bad faith polluting each side of the conversation.
I agree that there are fewer climate scientists, but I would also expect that any climate scientist who is not also a climate alarmist would have no chance of employment. Unless the employer is on the climate denial side, in which case the critical scientist would be automatically discredited by being employed by the wrong side.
I am saying that employers of climate scientists have expectations, because they are in one of the two camps. Do you know any major organization that the other camp would consider neutral?
Have you heard of a climate alarmist organization of employing a sceptic to validate their claim, or a climate sceptic organization employing an alarmist? That would be interesting.
I see your question and raise you a counter-question:
Define climate denier, please
I can actually answer both:
A climate alarmist is someone who agrees with the hypothesis that the planet is on the verge of a catastrophic climate change, generally assumed to be related to an increase in the average global temperature which is generally linked to human industrial activity, most notably the type of activity which involves the combustion of fossil carbon sources. This person will see the hypothetical climate catastrophe as the most important issue facing mankind and generally is willing to take drastic steps to limit its impact.
A climate denier is someone who does not agree with the hypothesis of an upcoming climate catastrophe. This does not imply the climate denier claims there is no such thing as climate change nor that human activity can and does influence climate, just that this person does not believe in an upcoming catastrophic climate upheaval.
The fact that these two terms are bandied around so easily shows how infected and polarised this issue has become. This is unfortunate as there are good arguments on both sides of the divide. The 'alarmists' generally want to get rid of fossil fuel dependencies which I consider to be a good idea, just not for the reasons they state and not with the urgency they crave. Fossil fuels are large sources of pollution (which is mostly but not entirely unrelated to the climate discussion), they are the root cause of many international conflicts. The 'deniers' generally want to keep a balance between the environmental and economical impact of reneging on or using fossil carbon sources which I tend to agree with even though I do not subscribe to the school of 'eternally growing economies'. Many on the 'denier' side are willing to increase the use of nuclear energy while many on the 'alarmist' side are averse to this option even though it offers many benefits in their goal of reducing carbon emissions. This is most likely related to the fact that the people who are on the 'alarmist' side of the divide generally identify with environmental causes which have (often successfully) fought investments in nuclear energy.
This is why it would be beneficial for all involved to open a true discussion on this subject, without throwing epithets at any and all who do not agree to the fully to a stated position.
Thank you for answering the question far better than I could.
Nuclear energy is the conundrum I fail to understand, especially here in Germany. If climate change is the most important threat to humanity, why not choose the relatively easy solution to use nuclear energy, or at least continue to operate the existing plants until there is a better alternative? Or put money into research to overcome the existing shortcomings of nuclear energy. Instead most climate alarmists in Germany want to shut down all nuclear plants and all nuclear research, most prominently the Green party, thereby increasing CO2 emissions. Does that imply that nuclear energy is an even worse threat to humanity? In that case, why don't they focus on fighting nuclear energy first, which is wide-spread especially in neighbouring France.
If you want to fight something, but don't want a solution, that makes me wonder what exactly you're fighting.
> Thank you for answering the question far better than I could
The OP has not answered what I have asked you and you still have not asked what is a climate alarmist and why you affirm that almost all climate scientists are climate alarmists
> A climate alarmist is someone who agrees with the hypothesis that the planet is on the verge of a catastrophic climate change
I have asked the OP because he has said that "I would also expect that any climate scientist who is not also a climate alarmist would have no chance of employment" implying that all climate scientists are alarmists.
> A climate denier is someone who does not agree with the hypothesis of an upcoming climate catastrophe.
Eh, no, a climate denier is someone that denies cliamte is changing or that the main force of change is humanity
> implying that all climate scientists are alarmists
Not exactly. I said that, to my knowledge, all employers of climate scientists are either on the alarmist side or on the denier/sceptic side. And I have yet to see an organisation that publishes opposing viewpoints.
That doesn't mean that climate researchers themselves are all on one side. I don't know their personal opinions, and I also think it that climate research is a field where having a valid opinion is very difficult. You can believe that a particular climate model is correct, and you can validate its prediction of the past, but you can't be sure it predicts the future accurately.
I would love to see a neutral organisation, but I have yet to find one. There are some that have a very neutral and rational tone, like the Copenhagen Consensus. But the alarmist side brands them as deniers, so I am not sure whether I can believe them either.
> Eh, no, a climate denier is someone that denies climate is changing
If you understand it literally, yes, but usually the it's about the exact impact of climate change. Nobody in his right mind can deny that CO2 has some impact. So denying means usually expecting less change.
Yes. Because the major selling point of it was linked to who actually made those arguments: "prominent scientists, etc". In fact there are very few scientists in the list, and I have not found a single "prominent" one.
> Augustinus Johannes "Guus" Berkhout (born 1940) is a Dutch engineer who has worked for the oil and gas industry, and as a professor. Berkhout started his career working for Shell.
> In 2019, Berkhout founded the climate change denial organization Climate Intelligence Foundation (CLINTEL).
"often" is a weasel word here. How about "sometimes"? Sometimes good questions come from outside a field. Nevertheless, when I'm suffering from a serious medical condition, I prefer to see a medical doctor. When my central heating packs up, I call a licensed gas-fitter.
Argument from authority seems like a bad plan. But arguing against someone _because_ they have authority seems worse.
However, we are not talking about treatment or repairs, so poor if not irrelevant comparisons.
It is recognised that the most valuable person/s in review panels are the rank outsiders that ask the questions that are considered already answered or too outlandish to consider.
There are a number of studies I can't be arsed to dig up, however Feynman and the challenger investigation is one slightly oblique example.
Outsiders do not have the fear of pointing at the elephant in the room.
I can't say much about the arguments themselves as I'm not competent enough, but many people on the list are not scientists, and many of those who are specialize in fields very distant from climate change.
The misleading title has some suggestion the letter is from the UN. But its a letter send to the UN.
The original title is 'Prominent scientists warn UN Secretary-General Guterres'. Already in the first sentence the story weakens further by explaining the 500 include 'professionals' as well - which can be anybody with a job, basicly.
I wish we could stop attacking the character of the scientists and instead consider the merit of their arguments.
I find it disturbing that so many people criticize some of the signers for ties to gas and oil, or to 'denier' groups. Yes, that just means they have had reason to study the issues. It does not mean they are evil or crazy.
This is an interesting point. I know nothing about climate science but do know a little about human behavior. I often had to figure out whether I thought a CEO was good at running a company or full of shit. So, the difficult part for me is figuring out what is true.
One thing I often try to figure out who/what is
incentivizing/motivating people to hold their viewpoint. While it's easy for people to see the oil/gas money, isn't the other side, and obviously, correct me if I’m wrong, also being incentivized/motivated by grants for academic studying and clean energy companies?
Another thing I often look at is the track record of people, especially if they are making predictions about the future. I’ve found that it’s a good indicator of how they will act in the future.
There is just declaration without any references. Nothing to argue against, besides blunt lies like:
"Only very few peer-reviewed papers even go so far as to say that recent warming is chiefly anthropogenic."
https://iopscience.iop.org/article/10.1088/1748-9326/11/4/04...
The consensus that humans are causing recent global warming is shared by 90%–100% of publishing climate scientists according to six independent studies by co-authors of this paper. Those results are consistent with the 97% consensus reported by Cook et al (Environ. Res. Lett. 8 024024) based on 11 944 abstracts of research papers, of which 4014 took a position on the cause of recent global warming. A survey of authors of those papers (N = 2412 papers) also supported a 97% consensus.
https://science.sciencemag.org/content/306/5702/1686 The 928 papers were divided into six categories: explicit endorsement of the consensus position, evaluation of impacts, mitigation proposals, methods, paleoclimate analysis, and rejection of the consensus position. Of all the papers, 75% fell into the first three categories, either explicitly or implicitly accepting the consensus view; 25% dealt with methods or paleoclimate, taking no position on current anthropogenic climate change. Remarkably, none of the papers disagreed with the consensus position.
"Only very few peer-reviewed papers even go so far as to say that recent warming is chiefly anthropogenic."
Calibrating climate change response is difficult, counting papers and surveying small populations is not.

If you read what these people (and many others with them) say you'd see that they also claim their position is staved by the data. They call for an opportunity to discuss these matters in public, without being shunned in the way you just did. If their ideas are as faulty as you seem to think they are your side would have nothing to lose by going into this discussion.
This rhetoric is part of what makes the 'climate change' movement look like a religion. Blind discipline, a statement of fact which can not be discussed, shunning of those who dare to differ, making a clear us versus them distinction with terms like climate science versus climate denial. You can even buy off you sins by paying for climate compensation.
Yes, the climate is changing as it has been doing for as long as there is a climate. Human activity has influence over the climate in many ways ranging from soot deposits on snow and ice fields (which warms them up) through local warming by direct emission to the emission of IR-active gases like CO₂ and CH₄. The role of CO₂ is disputable, it is not a strong 'greenhouse gas'. CH₄ is a strong greenhouse gas, as is water vapour. Condensed water (in the form of clouds) has the opposite effect by raising the planet's albedo (reflection coefficient). The amount of CO₂ in the atmosphere has risen since the end of the little ice age, partly due to human activity by burning fossil fuels, partly due to the increase in sea water temperature. How much of the rise is due to human activity is unclear, estimates range from 15 ppm (i.e. hardly anything) to nearly everything. The models used by the IPCC are incomplete (as all models are) and the predicted rise in global temperature turned out to be overstated by a large margin.
In 1972 a group of scientists at Brown University decided the science was clear on the fact that (I quote) the present rate of the cooling seems fast enough to bring glacial temperatures in about a century, if continuing as the present pace and sent a letter to then-president Nixon to warn him of the consequences of a global deterioration of climate, by order of magnitude larger than any hitherto experienced by civilized mankind. They were right in that a new ice will come but they were not correct in their estimate on when that would happen - Nixon did not have much to worry over in that respect.
There was no global public internet in 1972, there were no social media, there was no opportunity for celebrities to signal their social engagement and virtue by standing up and proclaiming that the time had come for all good men and women to act now or risk freezing in the impeding global climate catastrophe. The ice age scare largely was confined to a group of scientists with a few articles popping up here and there about increasing glacial masses and early winter snows. Had there been a global public internet in the early 70's and had Joan Baez, Sly and the Family Stone, Jimi Hendrix, Crosby, Stills, Nash and Young, Joni Mitchell and all the others spoken up... who knows what this would have led to. Imagine a second Woodstock 'for the climate', the public chanting 'no snow no snow no snow' instead of their previous rain-obverse incantation. Just imagine.
Also, don't treat this subject like a religion. It isn't. It is an important subject which should be subjected to all the rigours of the scientific method. That method does not tolerate dogma nor the shunning of differing voices. It is the observation which disproves your hypothesis you want to look for, not the opposite.
I was a bit shocked when I heard that the Greenland glacier is melting from the bottom. Arctic waters are feeding energy under it. It is melting at a higher rate than ever recorded before [1].
Here's a fun fact. Last 5 years are the hottest on record [2].
Tuvalu is sinking [3].
This isn't theoretical anymore. The change is coming, fast.

[3] https://edition.cnn.com/interactive/2019/05/world/tuvalu-cli...
Here's a strange fact: the last 5 years are only the hottest on record when compared to recent historical temperature data. Compared to previous historical temperature data (over the same period) the last 5 years are comparable to but not as extreme as the hot period in the mid-30's. This discrepancy started when meteorological institutions in parts of the world started 'correcting' their historical temperature records. The claimed reason for these corrections - which lower past temperatures while raising recent ones - is that they are necessary to make historical measurements comparable to recent and current ones. This claim has been tested and found wanting in the case of the Dutch meteorological office, KNMI [2 (in Dutch)]. NOAA in the US does the same type of corrections which are being criticised for being excessive but I have not yet found an impartial and detailed report laying out where exactly they went wrong.
Finally: Tuvalu is growing, not sinking [3].

This is irrelevant for the current trend

I suppose you have data to support this claim, isn't?
Consensus is irrelevant here, in the 1800s the consensus was that radiation travelled through the aether. This did not make it true even though it was the consensus.
> This is irrelevant for the current trend
Of course it is relevant for the current trend, it is those historical events which can be used to check climate models. This goes for both recent history (where direct measurements exist) as well as ancient history (where measurements need to be derived indirectly).
> I suppose you have data to back this claim, isn't?
Why, yes, there are many examples. There are many articles pointing out that CO₂ concentration seems to lag behind temperature changes instead of the other way around:
[1] "Temperature and atmospheric carbon dioxide are significantly correlated over the past thirty years. Changes in carbon dioxide content lag those in temperature by five months."
[2] "High-resolution records from Antarctic ice cores show that carbon dioxide concentrations increased by 80 to 100 parts per million by volume 600 ± 400 years after the warming of the last three deglaciations."
[3] "The lag was calculated for which the correlation coefficient of the CO2 record and the corresponding temperatures values reached a maximum. The simulation yields a lag of (1200 ± 700) yr."
[4] "The start of the CO2 increase thus lagged the start of the [temperature] increase by 800 ± 600 years."
[5] "Over the full 420 ka of the Vostok record, CO2 variations lag behind atmospheric temperature changes in the Southern Hemisphere by 1.3±1.0 ka"
[6] "The sequence of events during Termination III suggests that the CO2 increase lagged Antarctic deglacial warming by 800 ± 200 years and preceded the Northern Hemisphere deglaciation."
More on the 'greenhouse potential (GWP)' of CO₂ (and other IR-active gases like CH₄ and N₂O) in "Analyses of IPCC’s Warming Calculation Results" [7] et al.
As to the overestimation of the temperature increase all it takes is a look at the average temperature development versus the predicted temperatures to see the discrepancy. Some articles detailing this discrepancy:
[8] "Actual temperature measurements of 1958-2017 from three weather balloon datasets were compared to all 102 model runs. ... The mid-tropospheric warming trends in the models are caused by increasing water vapour in response to rising CO₂ levels due to flawed moist convection thermodynamic parametrization. Correcting the parametrization to match the temperature and water vapour amounts would greatly reduce the model’s climate sensitivities by reducing the water vapour feedback net of the smaller lapse rate feedback."
[9] "Why models run hot: results from an irreducibly simple climate model"
There are many more articles which pose questions around the accuracy and/or validity of the models on which the climate catastrophe hypothesis is based.

[5] eesmith ↗ Consider this through the lens of Young Earth Creationism vs. evolution. Yetanfou ↗ The comparison between YEC and evolution falls flat on its face because of the actual physical evidence in support of evolution where creationists have to call upon acts of god to support their hypothesis. It was god who put the dinosaur fossils in the soil to test the faith of his flock, it was god who twisted the laws of physics in such as way as to make it possible for cosmic background radiation to appear to show the universe as it looked ~14 billion years ago, etc. This dichotomy does not exist in the debate between the proponents of a climate catastrophe and those who do not hold with this hypothesis. Both sides call upon what they see as evidence for their stance, in this case the evidence mostly consists of models. Those models are both coarse-grained and limited in the factors they take into account. When tested against historical data the models have shown to grossly overstate the warming effect, they also leave out some important factors like cloud cover where a ~2% increase in cloud cover can negate the calculated warming effect so it is definitely a factor which should be included. eesmith ↗ Creationists say there is actual physical evidence in support of creationism.
The supporters of YEC claim their position is supported by data.
I think YEC's are flat-out wrong, and the physical evidence is so highly weighted in favor of old-Earth evolution that it's fantastical that they can maintain their position.
YEC's "call for an opportunity to discuss these matters in public, without being shunned". However, their positions have long since been demonstrated to be without basis. What YECs are looking for is fame, and influence, which they get by having a public debate 1) where the premise is that there is an argument, when there isn't, and 2) where people aren't permitted to call out the ridiculousness of their arguments.
You say the efforts of "the 'climate change' movement look like a religion". YECs say that evolution is also a religion.
Supporters of evolution have demonstrated that the YECs arguments are invalid. YECs repeat those arguments to new people, which shows they are not interested in the actual validity of those argument.
Your 1972 Brown University example parallels that structure. As https://skepticalscience.com/What-1970s-science-said-about-g... points out:
>> A persistent argument designed to discredit the field of climate science is that scientists predicted an ice age in the 1970s. So popular in fact that it ranks an impressive #7 in the most cited skeptic arguments. The logic goes that climate scientists got it completely wrong predicting global cooling in the 1970s (it started warming instead). Hence climate science can't be trusted about current global warming predictions. Setting aside the logical flaws of such an ad hominem argument, was there any consensus among 70s climate scientists predicting global cooling? ...
while a study of the scientific consensus in the 1970s shows:
>> in fact, the large majority of climate research in the 1970s predicted the Earth would warm as a consequence of CO2. Rather than climate science predicting cooling, the opposite is the case.
You write "The ice age scare largely was confined to a group of scientists with a few articles popping up here and there". While the evidence is quite the opposite - from the same link:
>> a 1975 Newsweek article The Cooling World that suggested cooling "may portend a drastic decline for food production ... A 1974 Times Magazine article Another Ice Age? painted a similarly bleak picture
It appears that the popular press did more to raise an ice age scare than the peer-reviewed scientific press.
Since you want "the rigours of the scientific method", surely you should apply that rigor to your own statements. Was the consensus of climate models of the 1970s really that of global cooling? Or are you repeating an argument long shown to be wrong?
What is the basis of your understanding of the 1970s climate models? Was it a cherry-picked minority viewpoint selected by climate change denialists more interested in fame and influence than the validity of their arguments?
Creationists are driven by religion. They may claim that evolution is also a religion but that is just playing with words and has no relation to the stand-off between those who support the climate catastrophe hypothesis and those who don't. In the former case religion was the main driver from the start, in the latter the movement got its start based on scientific studies. The current climate catastrophe hypothesis is not the first, there have been several predecessors. Some of these got some traction - the global cooling scare of the early '70s is one of these - while others languished. The religious undertone only became a factor in the current climate catastrophe hypothesis when it was picked up by mass media, celebrities, politicians and business interests who latched on to some parts of the IPCC reports and ran with it. Where the normal discourse in science, although heated, still remains open for discussion and by necessity for falsification, the non-scientific proponents of the climate catastrophe hypothesis had and have no such qualms. It is from there the claims of '97% of all scientists agree' and 'we only have 10/12/15 years left' arise, is is that group which coined the label 'climate denier'. The involvement of political groups in positions of power has made it a potentially career-limiting (or rather 'funding-limiting' but it comes down to the same thing) proposition to openly go against what is now becoming the dogma of the looming climate catastrophe.
This is not how science works. When a model has been proven to give the wrong results you adjust the model, you don't base policy on it. The models used by the IPCC have shown to overestimate warming by a large degree so they clearly are not showing the whole image. The reasons for the over-estimation can be several, most likely though is that the models don't take a limiting factors into account, cloud cover being a possible candidate. Instead of silencing those who follow the normal scientific method by falsifying a hypothesis these results should be taken into account and weighed for their validity, even when they come from a group which is ideologically opposed to yours.
Climate change is a real thing in the past and present, there is hardly anyone who denies this. Catastrophic climate change is a hypothesis. Anthropogenic catastrophic climate change is another hypothesis. The path from hypothesis to theory goes through attempted falsification, there is no other valid way. When presented with what is claimed to be a successful falsification the reaction should be to test it and when found valid lead to something like "well that is interesting, it looks like we missed something" instead of "go away heretic, we don't need your type around here". The former leads to better science, the latter to Lysenkoism.
Your "test the faith" example for the dinosaurs is at best incomplete. https://www.icr.org/article/how-do-dinosaurs-fit-in/ is an example of a YEC justification which does not use that argument.
My point was to say that your arguments are weak, because they apply equally well to those who defend creationism.
You again write "the global cooling scare of the early '70s is one of these".
As I pointed out, this was primarily a scare in the popular press of the time, while the general consensus in scientific literature was that increased CO2 would lead to global warming.
What you are spreading is, and I quote again, "#7 in the most cited skeptic arguments", and demonstrated to be an invalid argument.
The article I quote earlier addresses this point quite well:
"In 1997, the late Maurice Strong, former under-secretary-general of the United Nations, said: “Frankly, we may get to the point where the only way of saving the world will be for industrial civilization to collapse.”
In 1992, he proposed a single global government on environmental grounds: “It is simply not feasible for sovereignty to be exercised unilaterally by individual nation-states, however powerful. It is a principle which will yield only slowly and reluctantly to the imperatives of global environmental co-operation.”
In 2009, he declared his opposition to democracy: “Our concepts of ballot-box democracy may need to be modified to produce strong governments capable of making difficult decisions.”
In 2015, Christina Figueres, former executive secretary of the UN Framework Convention on Climate Change and now the head of a climate action lobby group, said: “This is probably the most difficult task we have ever given ourselves, which is to intentionally transform the economic development model, for the first time in human history.”
In 2016, Ottmar Edenhofer, former co-chair of the UN IPCC working group on Mitigation of Climate Change, said: “One has to free oneself from the illusion that international climate policy is environmental policy. This has almost nothing to do with the environmental policy anymore, with problems such as deforestation or the ozone hole. We redistribute de facto the world’s wealth by climate policy.”
Just a week ago, Saikat Chakrabarti, the chief of staff of Alexandra Ocasio-Cortez, the US politician famous for the Green New Deal that failed to pass Congress, was quoted in a glowing profile by the Washington Post saying: “The interesting thing about the Green New Deal is it wasn’t originally a climate thing at all. Do you guys think of it as a climate thing? Because we really think of it as a how-do-you-change-the-entire-economy thing.” "
For example, I've watched the "creation vs. evolution" so-called "debate" for about 20 years. I quoted "debate" because there is no debate, only continued raising by creationists of the same long-settled issues. (I speak here of Young Earth Creationists.)
But for someone without the specific training in biology (which, to be honest, is high-school level science often avoided in the US schooling I went to, in order to avoid offense to some religious belief holders), it's hard to tell that the creationist arguments and objections have no support in physical evidence, and that the creationists are often quote mining evolutionists. See http://www.talkorigins.org/faqs/quotes/mine/project.html .
To go back to your first comment, "There is money on both sides of the argument though."
There is also money on both sides of the creationist vs. evolutionist argument. And much more money on the evolutionist side. The US National Institutes of Health, to modify your quote, "sprays evolution money at anything that moves and at staggering rates — billions of dollars". Similarly, there are innumerable evolutionist companies which benefit handsomely from evolution.
But that spray, and those economic benefits, cannot be interpreted as support for Young Earth Creationism.
Since those arguments do not work for Young Earth Creationism, they are weak arguments at best, so cannot be a solid basis or proxy for understanding the issues related to global warming and climate change.
I call it a draw.
Are you saying that almost every climate scientist is a climate alarmist?
Define climate alarmist, please
Define climate denier, please
I can actually answer both:
A climate alarmist is someone who agrees with the hypothesis that the planet is on the verge of a catastrophic climate change, generally assumed to be related to an increase in the average global temperature which is generally linked to human industrial activity, most notably the type of activity which involves the combustion of fossil carbon sources. This person will see the hypothetical climate catastrophe as the most important issue facing mankind and generally is willing to take drastic steps to limit its impact.
A climate denier is someone who does not agree with the hypothesis of an upcoming climate catastrophe. This does not imply the climate denier claims there is no such thing as climate change nor that human activity can and does influence climate, just that this person does not believe in an upcoming catastrophic climate upheaval.
The fact that these two terms are bandied around so easily shows how infected and polarised this issue has become. This is unfortunate as there are good arguments on both sides of the divide. The 'alarmists' generally want to get rid of fossil fuel dependencies which I consider to be a good idea, just not for the reasons they state and not with the urgency they crave. Fossil fuels are large sources of pollution (which is mostly but not entirely unrelated to the climate discussion), they are the root cause of many international conflicts. The 'deniers' generally want to keep a balance between the environmental and economical impact of reneging on or using fossil carbon sources which I tend to agree with even though I do not subscribe to the school of 'eternally growing economies'. Many on the 'denier' side are willing to increase the use of nuclear energy while many on the 'alarmist' side are averse to this option even though it offers many benefits in their goal of reducing carbon emissions. This is most likely related to the fact that the people who are on the 'alarmist' side of the divide generally identify with environmental causes which have (often successfully) fought investments in nuclear energy.
This is why it would be beneficial for all involved to open a true discussion on this subject, without throwing epithets at any and all who do not agree to the fully to a stated position.
Nuclear energy is the conundrum I fail to understand, especially here in Germany. If climate change is the most important threat to humanity, why not choose the relatively easy solution to use nuclear energy, or at least continue to operate the existing plants until there is a better alternative? Or put money into research to overcome the existing shortcomings of nuclear energy. Instead most climate alarmists in Germany want to shut down all nuclear plants and all nuclear research, most prominently the Green party, thereby increasing CO2 emissions. Does that imply that nuclear energy is an even worse threat to humanity? In that case, why don't they focus on fighting nuclear energy first, which is wide-spread especially in neighbouring France.
If you want to fight something, but don't want a solution, that makes me wonder what exactly you're fighting.
The OP has not answered what I have asked you and you still have not asked what is a climate alarmist and why you affirm that almost all climate scientists are climate alarmists
I have asked the OP because he has said that "I would also expect that any climate scientist who is not also a climate alarmist would have no chance of employment" implying that all climate scientists are alarmists.
> A climate denier is someone who does not agree with the hypothesis of an upcoming climate catastrophe.
Eh, no, a climate denier is someone that denies cliamte is changing or that the main force of change is humanity
Not exactly. I said that, to my knowledge, all employers of climate scientists are either on the alarmist side or on the denier/sceptic side. And I have yet to see an organisation that publishes opposing viewpoints.
That doesn't mean that climate researchers themselves are all on one side. I don't know their personal opinions, and I also think it that climate research is a field where having a valid opinion is very difficult. You can believe that a particular climate model is correct, and you can validate its prediction of the past, but you can't be sure it predicts the future accurately.
I would love to see a neutral organisation, but I have yet to find one. There are some that have a very neutral and rational tone, like the Copenhagen Consensus. But the alarmist side brands them as deniers, so I am not sure whether I can believe them either.
> Eh, no, a climate denier is someone that denies climate is changing
If you understand it literally, yes, but usually the it's about the exact impact of climate change. Nobody in his right mind can deny that CO2 has some impact. So denying means usually expecting less change.
We have decades of experience with this. It's why scientists have to declare conflicts of interest: we know that it undermines their arguments.
Well let's see who this is.
https://en.wikipedia.org/wiki/Guus_Berkhout
> Augustinus Johannes "Guus" Berkhout (born 1940) is a Dutch engineer who has worked for the oil and gas industry, and as a professor. Berkhout started his career working for Shell.
> In 2019, Berkhout founded the climate change denial organization Climate Intelligence Foundation (CLINTEL).

Just because someone has a degree in a certain subject does not make them the only one that can ask questions about that subject.
This is called "White coat syndrome".
Argument from authority seems like a bad plan. But arguing against someone _because_ they have authority seems worse.
It is recognised that the most valuable person/s in review panels are the rank outsiders that ask the questions that are considered already answered or too outlandish to consider.
There are a number of studies I can't be arsed to dig up, however Feynman and the challenger investigation is one slightly oblique example.
Outsiders do not have the fear of pointing at the elephant in the room.

I find it disturbing that so many people criticize some of the signers for ties to gas and oil, or to 'denier' groups. Yes, that just means they have had reason to study the issues. It does not mean they are evil or crazy.
Does what they say make sense?
One thing I often try to figure out who/what is incentivizing/motivating people to hold their viewpoint. While it's easy for people to see the oil/gas money, isn't the other side, and obviously, correct me if I’m wrong, also being incentivized/motivated by grants for academic studying and clean energy companies?
Another thing I often look at is the track record of people, especially if they are making predictions about the future. I’ve found that it’s a good indicator of how they will act in the future.
There is just declaration without any references. Nothing to argue against, besides blunt lies like:
