Vincent Gray is a chemist based in New Zealand. He is a retired coal industry researcher, climate author, and founder of the New Zealand Climate Science Coalition .
Stance on Climate Change
"The 'globe' is simply not 'warming', for all of eight years. This year it will probably cool. Since all of the IPCC's models 'project' the 'likelihood' of a steady warming over this period, all of them must be wrong, and we can expect similar failures for all the other 'projections'." 
"The claims of the IPCC are dangerous unscientific nonsense." 
"The two main 'scientific' claims of the IPCC are the claim that 'the globe is warming' and 'Increases in carbon dioxide emissions are responsible'. Evidence for both of these claims is fatally flawed." 
Gray often introduces himself as an IPCC expert reviewer. He says that "I have been an 'Expert Reviewer' for The Intergovernmental Panel on Climate Change (IPCC) since its first major Report in 1990."
He uses this as justification for his continuous attack on the IPCC, having called  the panel "fundamentally corrupt," and describing their scientific methods as "unsound." Gray also published a book critiquing the IPCC titled The Greenhouse Delusion . The book describes the panel has having "not convincingly made its case that increases in carbon dioxide levels are occurring and [sic] that increase will have harmful effects." 
Although the National Post suggests that "no one has been a more faithful reviewer than Dr. Gray," all it takes  to be an expert reviewer is to refrain from publicly commenting on the draft. So just about anyone who requests to see a draft of the IPCC's report is qualified to be an IPCC expert reviewer.

Gray's signature is displayed  alongside a full-page ad funded by the CATO institute  that appeared  in numerous newspapers including the Washington Post, the New York Times and the Chicago Tribune in 2009.
The advertisement responds to President Obama's declaration that "few challenges facing America and the world are more urgent than combating climate change. The science is beyond dispute and the facts are clear" by saying that "with all due respect Mr. President, that is not true." It goes on to describe how "there has been no net global warming for over a decade," and how global warming is "grossly overstated." 
Published a paper titled "The Global Warming Scam" (PDF)  on the New Zealand Climate Science Coalition website.
The paper claims that "The Global Warming Scam has been perpetrated in order to support the Environmentalist belief that the earth is being harmed by the emission of greenhouse gases from the combustion of fossil fuels."

Gray signed an open letter  to the Secretary-General of the United Nations alleging that that the "UN climate conference is taking the World in entirely the wrong direction." It claimed that the process resulting in the IPCC report was flawed, and that if Global Warming really was human-caused that energy would be better spent trying to mitigate the damage it would do, as opposed to trying to stop it.

Gray set up the New Zealand Climate Science Coalition, a group with the aim of "refuting what it believes are unfounded claims about anthropogenic (man-made) global warming."

Gray is a signatory to an open letter to Prime Minister Stephen Harper titled "Open Kyoto to Debate ."
The letter claims that Global climate changes all the time due to natural causes and the human impact still remains impossible to distinguish from this natural 'noise.'"

A search of 22,000 academic journals shows that Gray has never been published in a peer-reviewed  journal on the subject of climate change. Gray has published peer-reviewed scientific work on coal, his most recent article having been published 17 years ago.
In one ICECAP article (PDF) , Gray touts his position as an "expert reviewer " of the IPCC. He further describes how the IPCC science has been "'spun' to support a global campaign to limit human emissions of certainb [sic] greenhouse gases which has no scientific basis."
Gray publishes  a newsletter called the NZ Climate and Envirotruth.
NZ Climate Truth provides the following description on their home page: "Vincent is too modest, the content is global in scope and his penetrating analysis honed by years of reviewing IPCC reports is applied to issues arising in the Greenhouse / Global Warming / Climate Change debate."
In 2004, Gray published a book, The Greenhouse Delusion : A Critique of "Climate Change 2001" . In it, Gray argues "that the quality and reliability of the IPCC's measurements are poor, the system of determining how much weight should be attributed to different influences on the earth's temperature is faulty, and the validity of evidence derived from computer modeling is questionable."
