NBC Nightly News anchor Brian Williams on Monday evening gave credibility to the extremist environmental theory that the Earth is reacting to mankind's mistreatment by spawning a rash of tornadoes. Williams reported how “this has been one of the most active, deadly tornado seasons in a long time” with more tornadoes so far this year than through August last year. He then forwarded to NBC Weather Plus meteorologist Bill Karins the kind of reasoning he hears during his daily routine:

I talked to three people, casual conversation today, all of them smart, saying “I don't know, we must be doing something to our Earth.”

Karins gently corrected him: “Well, there are correlations that can be made. Global warming not quite one of them. La Nina, more likely.”
