Ian Clark

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.

In 2004 Clark wrote a letter to the Editor of the "The Hill Times", suggesting a perspective at odds with published scientific evidence, saying:

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."
