From Free net encyclopedia

Dr. Ian Clark is a professor in the Department of Earth Sciences at the University of Ottawa. He is also director of G.G. Hatch Isotope Laboratories. His graduate work in isotope hydrogeology was at the University of Waterloo and the University of Paris.

In a March 2004 letter to The Hill Times, Clark wrote:

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.
