Second, skeptics argue that CO2 is not a pollutant but vital for plant life. Numerous field experiments have confirmed that higher levels of CO2 are positive for agricultural productivity. Furthermore, carbon dioxide is a very minor greenhouse gas. More than 90 percent of the warming from greenhouse gases is caused by water vapor. If you are going to change the temperature of the globe, it must involve water vapor.
Third, and most important, skeptics believe that climate models are grossly overpredicting future warming from rising concentrations of carbon dioxide. We are being told that numerical models that cannot make accurate 5- to 10-day forecasts can be simplified and run forward for 100 years with results so reliable you can impose an economic disaster on the U.S. and the world.
The revelation of Climategate occurs at a time when the accuracy of the climate models is being seriously questioned. Over the last decade Earth's temperature has not warmed, yet every model (there are many) predicted a significant increase in global temperatures for that time period. If the climate models cannot get it right for the past 10 years, why should we trust them for the next century?
Climategate reveals how predetermined political agendas shaped science rather than the other way around. It is high time to question the true agenda of the scientists now on the hot seat and to bring skeptics back into the public debate.
