Tom Victor Segalstad
- Ph.D., Geology/Geochemistry, University of Oslo. 
Tom Segalstad is an associate professor  of Resource and Environmental Geology at the University of Oslo and head of the University’s Geological Museum. 
He has listed himself as an “Expert Reviewer ” of the IPCC, which he has also mentioned at a media interview during the Heartland Institute's International Conference on Climate Change.
Under his research interests he lists “CO2 and the 'Greenhouse Effect,' and to be more specific, “how CO2 simply cannot cause 'global warming'.” 
Stance on Climate Change
“Man's contribution to atmospheric CO2 from the burning of fossil fuels is small, maximum 4% found by carbon isotope mass balance calculations. The ‘Greenhouse Effect’ of this contribution is small and well within natural climatic variability … The global climate is primarily governed by the enormous heat energy stored in the oceans and the latent heat of melting of the ice caps, not by the small amount of heat that can be absorbed in atmospheric CO2; hence legislation of 'CO2 taxes' to be paid by the public cannot influence on the sea level and the global climate.”

DeSmogBlog researched the co-sponsors behind Heartland's ICCC7  and found that they had collectively received over $67 million from ExxonMobil, the Koch Brothers and the conservative Scaife family foundations .
Spoke  at the Heartland Institute's International Conference on Climate Change. He was interviewed  by The New American during the conference where he contended that ice core samples are not representative of global Co2 levels. , 
His presentation was entitled, “Carbon Isotope Mass Balance Modeling of Atmospheric vs. Oceanic CO2.”
During the interview, Segalstad mentions that he was a “expert reviewer  to the IPCC,” and that he had asked why his scientific paper (PDF ) was not included in the report. When asked further about the IPCC, Segalstad said he “was not that close to the core of the IPCC.”

Was one of a list of “Commentors” to submit a document to the EPA titled “A Scientific Challenge of EPA's Proposed Finding of Endangerment that CO2, Methane, Nitrous OXide, Hydrofluorocarbons, Perflouorocarbons, and Sulfur Hexafluoride, Collectively on Individually, Are Causal Agent(s) or Contributors of Climate Change” (PDF ).
The commentors conclude that “… there is no 'cause and effect' relationship between CO2 and GTA [Global Temperature Anomalies].”
Similar petitions (<a href=”http://web.archive.org/web/20120603130037/http://epa.gov/climatechange/e... PDF) were released by the Southeastern Legal Foundation targeting the EPA's Endangerment Finding, with one (PDF ) citing Segalstad as a source. The EPA Responded  to Southeastern Legal, stating that “Segalstad's work 'does not address the lifetime of a change in atmospheric concentration of CO2, but rather the lifetime in the atmosphere of an individual molecule of CO2' and that these 'are two different concepts'.”
Southeastern Legal lists its partners  in their effort to reverse the EPA endangerment finding as the Science & Public Policy Institute , as well as “like-minded organizations” such as the Competitive Enterprise Institute , Heritage Foundation , CATO Institute , and the Independent Women’s Forum , among others.
The Manhattan Declaration asserts  that “human-caused climate change is not a global crisis,” that “(CO2) is not a pollutant but rather a necessity for all life,” that industrial carbon dioxide emissions do not affect climate change, and that “warmer weather is generally less harmful to life on Earth than colder.”
Segalstad's name appears on a submission (PDF ) from the Lavoisier Group to the Garnaut Climate Change Review.
The letter states that “The argument put forward by protagonists for decarbonisation that there is a scientific 'consensus' behind theories of a climate controlled by atmospheric carbon dioxide is clearly an attempt to silence critics, and should be treated with contempt.”
His name also appeared on the original letter to UN Secretary-General Ban Ki-Moon  that argued the science was not settled on climate change.
