In this December 15, 2011 video (below) Professor Ian Clark, Department of Earth Sciences at the University of Ottawa and director, G.G. Hatch Isotope Laboratories, one of Canada’s leading analytical facilities, testifies before a Canadian Senate hearing on climate change.
Professor Clark presents three important findings on what impacts the earth’s climate:
- Earths warming and cooling periods over millions of years has been due to activity on the sun.
- H2O (water vapor) is driving green house gas models, not CO2. It is H2O that keeps earth at a livable temperature for mankind.
- CO2 has little to do with global warming. CO2 actually helps keep the planet green.
Please take the time to watch this entire video to understand how data and science are used to define green house gases and their effect over time on our climate.
