It's I-Told-You-So Time

WASHINGTON (AP) — If you want a glimpse of some of the worst of global warming, scientists suggest taking a look at U.S. weather in recent weeks.

"This is what global warming looks like at the regional or personal level," said Jonathan Overpeck, professor of geosciences and atmospheric sciences at the University of Arizona. "The extra heat increases the odds of worse heat waves, droughts, storms and wildfire. This is certainly what I and many other climate scientists have been warning about."
