There is a claim doing the rounds that 500 Scientists have published evidence that refutes the prevailing climate consensus. Titled “There is no climate emergency“, this supposed European Climate Declaration that is dated 26th September 2019 contains a statement and a list of 500 scientists and professionals that endorse it. It was sent to Sr. António Guterres, Secretary-General of the United Nations on 23rd Sept, and was timed to align with the Climate Action Summit.
There are two things to look at here …
- Do they have a credible argument, actual data, for the stance they are taking?
- Who exactly are these people that are signing this, are they subject matter experts?
Let’s tackle each of these in turn.
Do the 500 have a credible argument?
A detailed analysis has been conducted by six climate scientists. They have analyzed the letter and estimate its overall scientific credibility to be ‘very low’. A majority of reviewers tagged the article as: Biased, Cherry-picking, Inaccurate, Misleading.
If you are in any way concerned that the arguments being presented by the letter are credible, then simply read the scientific rebuttal. Below is their quick summary.
Rebuttal to the 500 letter – Summary
This letter presenting a short list of claims about climate change boasts a list of “500 scientists and professionals” who have co-signed it.
The claims contradict or misrepresent the evidence uncovered by geoscientists, failing to provide support for its conclusions downplaying the threat of climate change. The letter claims, for example, that climate models ignore the benefits of increased CO2 on plant growth. This is false, as many climate models simulate the response of vegetation to increased CO2—and the climate change it causes.
And while some outlets described the co-signers as experts in climate science, most are not. As noted in an analysis below, a significant portion of the co-signers are either engineers or professionals in non-technical fields. Only 10 identified themselves as climate scientists.
Similar letters have sought to establish credibility with large numbers of co-signers in the past, but evidence is what counts in science.
Who exactly are these people that are signing this?
The letter claims that those that signed are “500 knowledgeable and experienced scientists and professionals in climate and related fields“. Let’s briefly review that claim.
It should of course be no surprise to learn that the list is bogus. The vast majority signing are not climate subject matter experts.
You might think that because they have a degree means that they are appropriately qualified.
Being a subject matter expert in one specific area does not in any way mean that you actually know anything about anything else. If you doubt that, then I wish you the very best of luck in seeking medical advice from a Doctor of Philosophy, or a mathematician, or a physicist, or even an engineer. You would be OK with that … right?
The list has supporters who signed, and also 14 Ambassadors. Perhaps the “Ambassadors” are all credible subject matter experts.
Unsurprisingly … no.
Alex Maycock has the details in the following twitter thread …
Briefly, these are the 14 Ambassadors, the supposedly best of the best…
- The guy who organised it all … Guus Berkhout – Retired engineer, worked in the oil and gas industry. Guus is the epitome of the “angry quitter” gaining several important roles in the Dutch science community over the years, only to storm out later shouting the Dutch equivalent of “You guys are stoopid meanies!”
- Richard Lindzen – A sloppy US meteorologist with an innate ability to make, in his own words, “some stupid mistakes”. Known ties to the #KochBrothers (see the documentary, Kochland) and a fellow at the Koch-funded Cato Institute.
- Reynald Du Berger – Retired Canadian seismologist and radio host of The Paranormal Chronicle. Seems to blame submarine volcanic and hydrothermal activity for climate change and acts as if he’s more pilloried in Quebec than @jordanbpeterson.
- Ingemar Nordin – Philosopher and founding member of The Stockholm Initiative, an organization known to spread lies about real climate scientists. It was voted “Confuser of the Year” in 2010 by Sweden’s Association of Science and Folk Education
- Terry Dunleavy – New Zealand winery owner. Former journalist and commercial printer, received the MBE in 1990 for services to the wine industry. Oh Terry, the Grapes of Wrath are coming for ya, mate.
- Jim O’Brien – Engineer who heads up the secretive and illegal lobbying outfit “Irish Climate Science Forum” – it’s illegal in that ICSF refuses to release its funding details, as per Irish law. What you got to hide, Jim? A Cato friend, perhaps?
- Viv Forbes – Australian libertarian, AKA the “Queensland-based coal-mining veteran.” Nuff said.
- Alberto Prestininzi – Maybe the only real climate scientist among this bunch of jokers, but subscribes to the “CO2 is food” philosophy. Hey Prof, know what happens when you eat too much food? You get fat and die.
- Jeffrey Foss – According to his students at BC’s University of Victoria, he’s a “Gonzo philosopher,” a “comedian” with a “nerve-wracking grading system” and the “weirdest human being ever” whose lectures are “kind of useless.” Admits to being afraid of the sun.
- Benoît Rittaud – “Claire Nouvian… had taken Élisabeth Lévy without restraint, as if her refusal to scream with the wolves on the climate allowed her media lynching.” Ah, French! Such a beautiful language. Matters not if you’re making sense, as long as it sounds vaguely sexual.
- Morten Jødal – Biologist who runs the Mushroom Guide, offering mushroom courses and mushroom products. Ozone hole sceptic and member of KLIMAREALISTENE, a very polite Norwegian climate denial group who believe climate change is real, but the sun is to blame for all of it.
- Fritz Vahrenholt – Chemist who once sat on the board of the German subsidiary of the Shell oil company. Former CEO of two renewable energy companies. Published a climate denial book in 2012 at about the same time that his company, RWE Innogy, dumped him.
- Rob Lemier – Belgian civil engineer. Loved climate change when it wasn’t cool, but hates it now everybody’s into it. So, obviously a #denialhipster.
- And finally… Christopher Monckton – Embarrassed the @UKHouseofLords so much they had to publish a Cease and Desist order, was banned by the #UN for invading the stage at @COP18, and is even too radical for UKIP – the Britain for the Brits party – so they dumped him.
This is not exactly a who’s-who of credible climate scientists. Instead it turns out to be Wingnuts-R-Us.
It would be funny if it was not so serious. We face the greatest threat our species has ever encountered, and these are the folks who are vigorously attempting to stop us from taking meaningful decisive action by spreading misinformation and outright lies on the basis of no credible data or evidence at all.
Scientific Rebuttal for the Climate Consensus denial
As a rather stark contrast to the above, here are the names, with links to their profiles, and summaries from actual climate scientists to the claims promoted by the bogus letter …
These comments are the overall assessment of scientists on the article, they are substantiated by their knowledge in the field and by the content of the analysis in the annotations on the article.
Timothy Osborn, Professor, University of East Anglia, and Director of Research, Climatic Research Unit:
This statement is unscientific. It ignores well-established understanding of climate and of what causes the climate to change. It makes cherry-picked statements, such as noting that some vegetation grows more with increased CO2 while ignoring the risks of serious damage arising from the climate change that is being caused by the same increase in CO2. The authors of the statement appear to be very unfamiliar with climate science: for example, they do not know that the amount of global warming we have observed is very close to the amount predicted by climate models.
Twila Moon, Research Scientist, University of Colorado, Boulder:
The letter contains direct lies and cherry picks information about carbon dioxide and climate change impacts that are designed to mislead. I am also concerned that many of those who have signed the letter are well known climate deniers and are not actively involved in direct research on climate change and its impacts.
Victor Venema, Scientist, University of Bonn, Germany:
The text is a masterpiece: next to the political opinions expressed, every single sentence is either wrong, insignificant or irrelevant for the question whether climate change is a serious problem for humanity. Given how old the “arguments” are, the authors are clearly not aiming to convince scientists and thus making science more political, while disingenuously claiming to be against that.
Amber Kerr, Researcher, Agricultural Sustainability Institute, University of California, Davis:
Each of the six claims has some element of truth to it (e.g. there is not much evidence that global warming is already making hurricanes more frequent). However, all six claims are presented in a biased and misleading way, giving the incorrect impression that anthropogenic climate change is a benign or beneficial force overall, whereas scientists and economists have repeatedly concluded that climate change is a massive and urgent problem.
Giorgio Vacchiano, Assistant Professor, Università di Milano:
The scientific content is completely inaccurate, undocumented, and fails to bring proof for its claims. The ending of the Little Ice Age in 1850 has no logical link with the fact that the Earth is warming now. Most past climate variations have been slower or less intense as the present one, and if they were as fast or severe they brought about mass extinctions in the biosphere. No explanation or proof is brought on the implausibility or inaccuracy of climate models (whose accuracy or uncertainty is precisely quantified and makes their use better than just random guesses). The last two statements are based on literature and common knowledge, but qualify as cherry-picking because they omit most negative effects of CO2 increase and warming (e.g. other clear trends in extreme events, damage to forests and crops by drought and heat waves).
You are faced with a choice.
Do you go with the vague unsubstantiated ramblings of the eccentric wingnut brigade, or do you instead lean upon the evidence-based conclusions of every scientific body and educational institution on the planet?
Damn it; that is such a hard choice to make.
