This weekend, 60 Minutes will air an interview with Bob Correll, one of the leading climate scientists. The tease on the 60 Minutes website has Correll saying that global warming is, in effect, the cause of stronger hurricanes, such as Katrina, and that future storms will be even more severe.

Here's another good primer:

"This is bellwhether, a barometer … the warning that things are coming," says Corell, who also predicts lowlands will be inundated by waters from the melting glaciers in the future. "In 10 years here in the arctic, we see what the rest of the planet will see in 25 or 35 years from now," he says. "The entire planet is out of balance."

It sounds like the interview will be a good edition to the barrage of recent reports on global warming.
