Ian Clark

From Wikipedia, the free encyclopedia

Ian Clark is a professor in the Department of Earth Sciences at the University of Ottawa. His graduate work in isotope hydrogeology was at the University of Waterloo and the University of Paris.[1]

In 2004 Clark wrote a letter to the Editor of the The Hill Times saying:

“ That portion of the scientific community that attributes climate warming to CO2 relies on the hypothesis that increasing CO2, which is in fact a minor greenhouse gas, triggers a much larger water vapour response to warm the atmosphere. This mechanism has never been tested scientifically beyond the mathematical models that predict extensive warming, and are confounded by the complexity of cloud formation - which has a cooling effect.[2] ”

In the 2007 UK television documentary The Great Global Warming Swindle he argues that changes in global temperature correlate with solar activity, saying "Solar activity of the last hundred years, over the last several hundred years correlates very nicely on a decadal basis, with sea ice and Arctic temperatures."[3] The data presented in the movie, however, omits parts of the record that demonstrate that solar activity cannot explain current warming, contributing to the view that this documentary was not intended to present scientific evidence fairly. Clark's scientific record does not include any peer reviewed publication on the subject of anthropogenic climate change.
