“Not CO2, but water vapor is the most important greenhouse gas"
Hmmm...I wonder how Al Gore intends to reduce our water vapor footprint...lol
Belgium: Climate scientist Luc Debontridder of the Belgium Weather Institute’s Royal Meteorological Institute (RMI) co-authored a study in August 2007 which dismissed a decisive role of CO2 in global warming: "CO2 is not the big bogeyman of climate change and global warming. “Not CO2, but water vapor is the most important greenhouse gas. It is responsible for at least 75 % of the greenhouse effect. This is a simple scientific fact, but Al Gore's movie has hyped CO2 so much that nobody seems to take note of it.”
