The 97% “consensus” study, Cook et al. (2013) has been thoroughly refuted in scholarly peer-reviewed journals, by major news media, public policy organizations and think tanks, highly credentialed scientists and extensively in the climate blogosphere.
The shoddy methodology of Cook’s study has been shown to be so fatally flawed that well-known climate scientists have publicly spoken out against it:
“The ‘97% consensus’ article is poorly conceived, poorly designed, and poorly executed. It obscures the complexities of the climate issue and it is a sign of the desperately poor level of public and policy debate in this country [UK] that the energy minister should cite it.”
– Mike Hulme, Ph.D. Professor of Climate Change, University of East Anglia (UEA)
The following is a list of 97 articles that refute Cook’s (poorly conceived, poorly designed and poorly executed) 97% “consensus” study. The fact that anyone continues to bring up such soundly debunked nonsense like Cook’s study is an embarrassment to science.
Summary: Cook et al. (2013) attempted to categorize 11,944 abstracts of papers (not entire papers) to their level of endorsement of AGW and found 7930 (66%) held no position on AGW. While only 65 papers (0.5%) explicitly endorsed and quantified AGW as +50% (Humans are the primary cause).
Their methodology was so fatally flawed that they falsely classified skeptic papers as endorsing AGW, apparently believing to know more about the papers than their authors.
Cook et al.’s author self-ratings simply confirmed the worthlessness of their methodology, as they were not representative of the sample since only 4% of the authors (1189 of 29,083) rated their own papers and of these, 63 % disagreed with their abstract ratings.

Rebuttals to Criticisms:
Criticism: Tol (2014) was rejected by other journals for being flawed.
Rebuttal: Dr. Tol’s paper was censored by Environmental Research Letters (ERL), which conveniently has multiple alarmists scientists on its editorial board (e.g. Peter Gleick and Stefan Rahmstorf) and rejected by two other journals for being “out of scope” (off-topic) not flawed.
Criticism: Tol (2014) has 24 errors in it.
Rebuttal: Dr. Tol refuted all of these claims in a post online and in his published rejoinder.

Kenneth Dyson. is 1.5 trillion dollars per year enough motivation for you?
N”ew estimates published by the Climate Change Business Journal put the total size of the industry at $1.5 trillion a year, or $4 billion a day, equivalent to the size of the global online retail market. The figure includes carbon markets, carbon consulting, biofuels, carbon sequestration, renewable technologies, eco buildings and hybrid cars.”
“The climate change consultancy market alone is worth $1.9 billion worldwide; $670 million in the United States, thanks to businesses need to keep on top of climate policy. And these figures are expected to more than double by 2020.”
Science is supposed to be about induction, reasoning from observation,
experimentation, etc. to conclusions. Debate is supposed to be about whether the methodology is applied correctly. If it is, then the conclusions are true. If not, conclusions are rejected.
Leftists have tried to make science deductive, as in, conclusion oriented. Championed by Stalin’s pet scientist Trofim Denisovich Lysenko, debate is centered on whether proposed conclusions are acceptable to a specific ideological outlook. If politically correct, conclusions are accepted. If not, then conclusions are rejected and their proponents silenced — permanently.
In the former Soviet Union, dissenting scientists were sent to the Gulag. In the U.S., leftists have to settle for character assassination and/or legal harassment.
Hi,
Just curious. What is the motivation behind those promoting this hoax. From my perspective I would figure it would be more profitable to hitch a ride on the “drill baby drill” train. Is there really that much money in the alternative energy/ conservation industry? Or is money not the motivating factor? Thanks for your input.
What is the motivation behind those promoting this hoax.
Hey Kenneth! Money and power.
For those who wish to rule the world, CO2 regulations can dictate your every decision, from how many children you have to the food you eat. CAGW is a totalitarian’s wet dream.
For those who wish to profit off totalitarian misery, there are endless funds available through government taxation. CAGW is a 1.5 trillion dollar industry that rewards useful idiots, and punishes those who refuse to submit.
“The $1.5 trillion global ‘climate change industry’ grew at between 17 and 24 percent annually from 2005-2008, slowing to between 4 and 6 percent following the recession with the exception of 2011’s inexplicable 15 percent growth, according to Climate Change Business Journal,” he writes.

Money and power, what every greedy politician is after.
And, every crony capitalists.
If you’re paying attention, you can see that the only solution to the “climate change” problem seems to be more government control over our lives. THAT is the motivating factor.
And, lots of our money.
So sad to recognize that even when alarmist claims are debunked, skewed data exposed, and dire predictions of rising sea levels, and disappearing polar bears failing to materialize, there are still those who are determined to believe in “catastrophic man-made climate change (formerly global warming). They have bought into all the lies and hype produced by those who stand to profit mightily by sucking the teat of research dollars from the stupid governments of the world, allegedly searching for a way or ways to stop/minimize the ‘disastrous’ events that are predicted to occur because of preventable climate change. I wonder how many of those dollars get siphoned off by the politicos who approve the grants that fuel this nonsense, let alone the ‘researchers’ and ‘climate evangelists’ (think Al Gore) who gleefully take the money thrown at them. No wonder they fight so hard to deny the truth and marginalize those who recognize it. No wonder many real scientists confess to their closest friends that they are forced to ‘go along or be ejected from the fraternity of fellow scientists and any hope of grant monies’. The 97 articles above just proves how desperate they are to make the world believe in AGW. These aren’t the first misrepresentations and skewing of data that has come down the pike either. Some folks just seem to need a crises to fight. As if we didn’t already have enough REAL threats to our survival to deal with.
Hi,
Just curious. What exactly is the motivation for perpetuating the hoax? From my perspective I woyld venture that it would be more profitable to hitch a ride on the “drill baby drill” train. Is there really that much money in the alternative energy market? Or is money not the motivator here? Thanks.
There is a lot of money in drilling, you are right. But to access it you must have the capital to invest in drilling equipment, R&D, exploration, etc.
For a scientist that capital is not available, but the entity that consumes a third of our 17 trillion dollar GDP routinely gives away fortunes in research grants as long as it supports what you are researching. Make sense now?
“They have bought into all the lies and hype produced by those who stand to profit mightily by sucking the teat of research dollars from the stupid governments of the world, ”
So, on one hand there’s money, and on the other there’s political power. Learn to read.
Think of every university professor, politician, media personality, government funded scientist, journalist, and many others that have hitched their career if not their identity to the AGW train. Also keep in mind the mission of the U.N. to trump all nation members sovereignty with climate/energy policy written on the intergovernmental level.
With all that riding on AGW being absolutely accepted by everyone there is no mystery as to why they push such a thoroughly debunked theory.
I hope you all remember your moronic denial of this current event when half of the coastal cities are flooded.
Mr Brown, your breathless and meaningless taunt has zero basis in reality. Sea levels are not rising any faster than they have since the end of the LIA. You alarmists are the worst sort of science and nature deniers, always acting out the age old belief that man causes weather and should therefore make sacrifices to appease Gaia.
Feel free to comment again when you have something relevant to the real world to discuss.
What do you expect from a cartoon character!
According to Al Gore? Or the IPCC? The IPCC doesn’t even make that sort of nonesense claim. Do some fact checking.
Charlie Brown, weren’t they supposed to be already? Lol, clown.
So let’s accept for the moment that the lie of global warming is true, anyone remember 30 yrs ago when the same nut cases pushed an ice age coming and then 10 yrs later changed to warming and now it’s climate change. Note to all who read this: the climate is always changing since the planet formed, was it humans that started the last ice age after all Fred and Barney had a stone age car or maybe it was dino blowing gas out of his ; well you know!
Those “nut cases” are the people who revise their findings in the face of evidence. It’s called “science” and “the scientific method”. It doesn’t stick to old precepts in the face of new evidence. Unlike the deniers.
So why are the nutcases not revising their failed hypothesis in the light of new evidence? Why do ghe nutcases deny natural climate change? The only science deniers are those that deny that natural variability can explain every global climate change we have witnessed.
Leftists can easily be identified by their prerequisite psychological projection. Science deniers are those who reject skepticism and the natural world around us.
