Federal forecasters predict a warming of the central Pacific Ocean this year that will change weather worldwide, and that's good news for a weather-weary United States.

The warming, called an El Nino, is expected to lead to fewer Atlantic hurricanes, more rain next winter for drought-stricken California and southern states, and even a milder winter for the nation's frigid northern tier next year.

Elsewhere in the world, it can mean an even hotter year coming up, with billions of dollars in losses for food crops.
