"Anyway, the warming of the Canadian Arctic due anthropogenic climate change..."

After reading that I could take nothing he wrote seriously.

You are misreading him. In this sentence he is describing the plot of a movie. He may very well believe in AGW, but you can't deduce it from his description of a movie.

The notion of early man as a Typhoid Mary causing mass extinctions is a new one to me. But it sounds like a load of bull. As the author says, disease organisms are usually too exquisitely adapted to their hosts to jump to multiple species.

[Bernard Marx]

I admit I quickly skim-read and could be guilty as charged.

I agree that early man and his diseases causing animal extinctions is BS. Something not yet understood happened to cause the Pleistocene megafauna extinctions. Eventually we'll probably figure it out but pontificating on the basis of present evidence is pointless.
