It's impossible to delve into Dyson's career without concluding he is several orders of magnitude smarter than the Al Gores of the world.
One of his themes is the complexity of the universe.
He thus gets a good laugh at all of the simplifiers of science, such as Gore and the rest of the what I like to call the climate scientology cult.
Anyone who knows anything about science realizes that something as complex as the Earth's atmosphere offers too many variables to be understood in a matter of mere years.
Research is just beginning into the role of carbon dioxide in the atmosphere, yet the climate scientologists claim to know exactly what effect each tiny increment of CO-2 will have on the environment.
