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

Unfortunately things are different in climate science because the arguments have become heavily politicised. To say that the dogmas are wrong has become politically incorrect.

The world of science and the world of literature have much in common. Each is an international club, helping to tie mankind together across barriers of nationality, race and language. I have been doubly lucky, being accepted as a member of both.

What we see today is an American economy that has boomed because of policies and developments of the 1950s and '60s: the interstate-highway system, massive funding for science and technology, a public-education system that was the envy of the world and generous immigration policies.

Learn about the world, the way it works, any kind of science and anthropology, it's really an interesting place we live in. Evolution is a really fantastic idea, even more than the idea of God I think.
