Global warming scientists hit a rough patch this winter over private emails. But they're back with an apocalyptic vision of your future.

Stanford's Noah Diffenbaugh and Moetasim Ashfaq predict routine heat waves by 2039, which may damage agriculture and health.

"In the next 30 years, we could see an increase in heat waves like the one now occurring in the eastern United States or the kind that swept across Europe in 2003 that caused tens of thousands of fatalities. Those kinds of severe heat events also put enormous stress on major crops like corn, soybean, cotton and wine grapes, causing a significant reduction in yields."
