For the sake of argument, here are some notes about the people in Mike's list and what they actually said.
* Dr. Edward Wegman, a mathematician, said "We were not asked to assess the reality of global warming and indeed this is not an area of our expertise."
* Dr. David Bromwich - his research is based primarily on single site assessments at Amundsen-Scott Research Station. He does not deny the reality of anthropogenic climate change.
* Prof. Paul Reiter has not denied the reality of global warming, he has merely questioned the relationship between it and the effects on mosquito-borne diseases. He sits on the council of an organization called the 'Annapolis Centre for Science-Based Public Policy' which has received $763,500 in funding from ExxonMobil.
* Prof. Hendrik Tennekes is an aeronautical engineer. His opinion matters why?
* Dr. Christopher Landsea has said "we certainly see substantial warming in the ocean and atmosphere over the last several decades ..., and I have no doubt a portion of that, at least, is due to greenhouse warming."
* Dr. Antonino Zichichi has made a career out of controversy. He is widely ridiculed in the scientific community for his error-strewn publications.
* Dr. Richard Lindzen is also a member of 'Annapolis Centre for Science-Based Public Policy' which receives major funding from ExxonMobil. He also works for 'Cato Institute' - again funded by ExxonMobil.
* Dr. Zbigniew Jaworowski is criticised by Professor Hans Oeschger who says that some of Jaworowski claims are "drastically wrong from the physical point of view".
* Dr. Syun-Ichi Akasofu - "it is in the best interests of mankind to reduce the rate of increase of our release of CO2 ... Prominent climate change is in progress in the Arctic"
* Dr. Claude Allegre - 20 years ago in "Clés pour la géologie", he wrote "By burning fossil fuels, man increased the concentration of carbon dioxide in the atmosphere which, for example, has raised the global mean temperature by half a degree in the last century". He now says "The cause of this climate change is unknown".
* Dr. Habibullo Abdussamatov claims that solar activity is the main contributor to climate change have been discredited -

* Dr. Richard Tol, an economist, does not deny the reality of anthropogenic climate change, he has merely debated the economic impact.
* Dr. Sami Solanki - "since about 1980, while the total solar radiation, its ultraviolet component, and the cosmic ray intensity all exhibit the 11-year solar periodicity, there has otherwise been no significant increase in their values. In contrast, the Earth has warmed up considerably within this time period. This means that the Sun is not the cause of the present global warming."
* Prof. Freeman Dyson - "One of the main causes of warming is the increase of carbon dioxide in the atmosphere resulting from our burning of fossil fuels such as oil and coal and natural gas."
* Dr. Eigils Friis-Christensen does not deny the reality of anthropogenic climate change and does not suggest that the sun "could account for most of the warming" -
