In the history of science it has often happened that the majority was wrong and refused to listen to a minority that later turned out to be right.
We simply don't know yet what's going to happen to the carbon in the atmosphere.
We do not know how much of the environmental change is due to human activities and how much [is due] to long-term natural processes over which we have no control.
When I listen to the public debates about climate change, I am impressed by the enormous gaps in our knowledge, the sparseness of our observations and the superficiality of our theories.
The biologists have essentially been pushed aside. Al Gore's just an opportunist. The person who is really responsible for this overestimate of global warming is Jim Hansen. He consistently exaggerates all the dangers.
Unfortunately the global warming hysteria, as I see it, is driven by politics more than by science.
There is no doubt that parts of the world are getting warmer, but the warming is not global.
Vegetation is really controlling what happens...whereas the emphasis in the climate models has always been on the atmosphere.
