The hottest, wettest year ever: By the numbers

Although much of the nation has been hammered by unusually frigid air this winter, new data released Wednesday by the government indicates that, globally, 2010 was the warmest, wettest year on record (although it shared the "warmest year" title with 2005). "The warmth this year reinforces the notion that we are seeing climate change," and "unequivocally" disproves notions that climate warming ended in 2005, says David Easterling, chief of the National Oceanic and Atmospheric Administration's scientific services division. Here, a brief guide, by the numbers, to the record-breaking weather:

2010

Hottest year on record, globally, in a tie with 2005. It was also the wettest year ever recorded — "no surprise to the Pakistanis, Australians, Tennesseans, and Californians who lived through epic floods," says Justin Gillis in The New York Times.
