“I am of the opinion that this is one of the greatest hoaxes ever perpetrated on the American people.”

‘Global warming is a non-problem’ – ‘I say this to Obama: Excuse me, Mr. President, but you’re wrong. Dead wrong.’

-Nobel Prize Winning Physicist Dr. Ivar Giaever

“We, the undersigned, having assessed the relevant scientific evidence, do not find convincing support for the hypothesis that human emissions of carbon dioxide are causing, or will in the foreseeable future cause, dangerous global warming."

-The Climate Scientists' Register, 2016

• My blood simply boils too hot when I read the blather, daily, about climate catastrophe. It boggles the mind that I could be certain that I know what caused a half degree rise in the last hundred fifty years. It’s simply not large enough to find a physical cause.

-Professor Dr. Caleb Rossiter

• It is of course, the global warming scam, with the (literally) trillions of dollars driving it, that has corrupted so many scientists, and has carried APS before it like a rogue wave.

  It is the greatest and most successful pseudoscientific fraud I have seen in my long life as a physicist.

  Anyone who has the faintest doubt that this is so should force himself to read the ClimateGate documents, which lay it bare.

-Harold Lewis, Emeritus Professor of Physics at the University of California, Santa Barbara

• “Temperature measurements show that the [climate model-predicted mid-troposphere] hot zone is non-existent. This is more than sufficient to invalidate global climate models and projections made with them!”

-UN IPCC Scientist Dr. Steven M. Japar (H/T Climate Depot)

• Warming fears are the “worst scientific scandal in the history…When people come to know what the truth is, they will feel deceived by science and scientists.”

-UN IPCC Japanese Scientist Dr. Kiminori Itoh, an award-winning PhD environmental physical chemist. (H/T Climate Depot)

• ‘We can expect climate crisis industry to grow increasingly shrill, and increasingly hostile toward anyone who questions their authority’

-Dr. Kenneth Green (H/T Climate Depot)

• “I was at the table with three Europeans, and we were having lunch. And they were talking about their role as lead authors. And they were talking about how they were trying to make the report so dramatic that the United States would just have to sign that Kyoto Protocol.”

–Alabama State Climatologist Dr. John Christy (H/T Climate Depot)

• “Gore prompted me to start delving into the science again and I quickly found myself solidly in the skeptic camp…Climate models can at best be useful for explaining climate changes after the fact.”

–Meteorologist Hajo Smit of Holland (H/T Climate Depot)

• “The quantity of CO2 we produce is insignificant in terms of the natural circulation between air, water and soil… I am doing a detailed assessment of the UN IPCC reports and the Summaries for Policy Makers, identifying the way in which the Summaries have distorted the science.”

–South African Nuclear Physicist and Chemical Engineer Dr. Philip Lloyd, a UN IPCC co-coordinating lead author (H/T Climate Depot)

• Hurricane expert Christopher W. Landsea of NOAA’s National Hurricane Center, was both an author a reviewer for the IPCC’s 2nd Assessment Report in 1995 and the 3rd Assessment Report in 2001, but resigned from the 4th Assessment Report after charging the UN with playing politics with Hurricane science.

  Landsea wrote a January 17, 2005 public letter detailing his experience with the UN: “I am withdrawing [from the UN] because I have come to view the part of the IPCC to which my expertise is relevant as having become politicized. In addition, when I have raised my concerns to the IPCC leadership, their response was simply to dismiss my concerns.”

  “I personally cannot in good faith continue to contribute to a process that I view as both being motivated by pre-conceived agendas and being scientifically unsound,” Landsea added. (H/T Climate Depot)

• “The Kyoto theorists have put the cart before the horse. It is global warming that triggers higher levels of carbon dioxide in the atmosphere, not the other way round…A large number of critical documents submitted at the 1995 U.N. conference in Madrid vanished without a trace. As a result, the discussion was one-sided and heavily biased, and the U.N. declared global warming to be a scientific fact.”

-Andrei Kapitsa (H/T Climate Depot)

• I believe advocacy by climate scientists has damaged trust in the science. We risk our credibility, our reputation for objectivity, if we are not absolutely neutral. At the very least, it leaves us open to criticism. I find much climate scepticism is driven by a belief that environmental activism has influenced how scientists gather and interpret evidence.

-Tamsin Edwards, climate scientist at the University of Bristol

• <2009> Briffa: I find myself in the strange position of being very skeptical of the quality of all present reconstructions, yet sounding like a pro greenhouse zealot here!

• I participated in a panel discussion in the Nobel meeting in Lindau in 2008 where I said the global warming has become a new religion. Please see the statement from the American Physical Society where it is stated: The evidence is incontrovertible; i.e. it can’t be discussed, just like religion.

  The [society] will discuss the mass of a proton for example, or negative energy, but global warming is incontrovertible….

  We have gone through this before: the acid rain used to be a big problem, then the ozone hole took over and Freon is no longer used for refrigeration which costs you dearly, and now finally we have global warming to worry about. But there is NO unusual rise in the ocean level, so what where and what is the big problem?

-Ivar Giaver, a winner of the physics Nobel

• "By now everyone has heard of what has come to be known as ClimateGate, which was and is an international scientific fraud, the worst any of us have seen...

  We have asked the APS management to put the 2007 statement on ice until the extent to which it is tainted can be determined, but that has not been done. We have also asked that the membership be consulted on this point, but that too has not been done."

-William Happer, a physicist who runs the Happer Lab at Princeton University, Hal Lewis, a professor emeritus of physics at the University of California, Santa Barbara, and Robert Austin, another Princeton physics professor and head of a biophysics research group.

• The central problem of climate science is to ask what you do and say when your data are, by almost any standard, inadequate? If I spend three years analyzing my data, and the only defensible inference is that “the data are inadequate to answer the question,” how do you publish? How do you get your grant renewed?

  A common answer is to distort the calculation of the uncertainty, or ignore it all together, and proclaim an exciting story that the New York Times will pick up.

-Carl Wunsch

• An Obama supporter who describes himself as "100 per cent Democrat," Dyson says he is disappointed that the President "chose the wrong side." Increasing CO2 in the atmosphere does more good than harm, he argues, and humanity doesn't face an existential crisis. Climate change, he tells us, "is not a scientific mystery but a human mystery.

  How does it happen that a whole generation of scientific experts is blind to obvious facts?"

• "We are dealing with pure political propaganda that has nothing to do with science."

-Dr. Patrick Moore

• "Demonization of CO2 is irrational at best and even modest warming is mostly beneficial."... "When someone says this is the warmest temperature on record. What are they talking about? It’s just nonsense. This is a very tiny change period."

-MIT Climate Scientist Dr. Richard Lindzen

• I want to discuss a contemporary moral epidemic: the notion that increasing atmospheric concentrations of greenhouse gases, notably carbon dioxide, will have disastrous consequences for mankind and for the planet.

  The “climate crusade” is one characterized by true believers, opportunists, cynics, money-hungry governments, manipulators of various types—even children’s crusades—all based on contested science and dubious claims.

-William Happer

“The fundamental point has always been this. Climate change is governed by hundreds of factors, or variables, and the very idea that we can manage climate change predictably by understanding and manipulating at the margins one politically selected factor (CO2) is as misguided as it gets.”

  “It’s scientific nonsense.”

-University of London professor emeritus Philip Stott

I started saying that scientists should be more accountable, and I began to engage with sceptic bloggers. I thought that would calm the waters. Instead I was tossed out of the tribe.

  There’s no way I would have done this if I hadn’t been a tenured professor, fairly near the end of my career. If I were seeking a new job in the US academy, I’d be pretty much unemployable. I can still publish in the peer-reviewed journals. But there’s no way I could get a government research grant to do the research I want to do.

  Since then, I’ve stopped judging my career by these metrics. I’m doing what I do to stand up for science and to do the right thing.

-Dr. Judith Curry

AGW Predictions Really About Getting Research Funding and Votes...

  "You will never read or hear any of this from the scientific and political establishments. I’m now retired, so I have no scientific career to protect by spreading lies.

  "Too many (the majority) of climate research scientists are quite willing to prostitute their science by giving these politicians what they want."

Five Hundred Scientists: There is no climate emergency...

Your Excellencies,

There is no climate emergency.

A global network of more than 500 knowledgeable and experienced scientists and professionals in climate and related fields have the honor to address to Your Excellencies the attached European Climate Declaration, for which the signatories to this letter are the national ambassadors.

The general-circulation models of climate on which international policy is at present founded are unfit for their purpose. Therefore, it is cruel as well as imprudent to advocate the squandering of trillions on the basis of results from such immature models. Current climate policies pointlessly, grievously undermine the economic system, putting lives at risk in countries denied access to affordable, continuous electrical power...

Richard Lindzen

MIT Atmospheric Physicist

  I’m an atmospheric physicist. I’ve published more than 200 scientific papers. For 30 years I taught at MIT, during which time the climate has changed remarkably little.

  But the cry of “global warming” has grown ever more shrill. In fact, it seems that the less the climate changes, the louder the voices of the climate alarmists get.

  So, let’s clear the air and create a more accurate picture of where we really stand on the issue of global warming or, as it is now called—“climate change.” -Richard Lindzen

-Richard Lindzen

A common misunderstanding amongst the general public, mainstream media and politicians is that only a small proportion of experts in the climate science community have serious problems with the concept of a carbon dioxide-driven climate crisis. In reality, thousands of climate experts are highly skeptical of this hypothesis.

  This fact has been repeatedly demonstrated through open letters, petitions and other declarations. However, these documents have not had sufficient impact on government policy largely because mainstream media have generally ignored them and so only a minority of the public is aware of their existence.
