The idea that global warming is the most important problem facing the world is total nonsense and is doing a lot of harm.

Global warming is real - it is man-made and it is an important problem. But it is not the end of the world.

Unfortunately the global warming hysteria, as I see it, is driven by politics more than by science.

On average, global warming is not going to harm the developing world.

Esso has been the main one in America spreading the disinformation that there is no global warming problem.

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.
