In U.S., 2012 so far is hottest year on record

The first eight months of 2012 have been the warmest of any year on record in the contiguous United States, and this has been the third-hottest summer since record-keeping began in 1895, the U.S. National Climate Data Center said on Monday.

Each of the last 15 months has seen above-average temperatures, something that has never happened before in the 117 years of the U.S. record, said Jake Crouch, a climate scientist at the data center.
