2007 a year of weather records in U.S.

WASHINGTON - When the calendar turned to 2007, the heat went on and the weather just got weirder. January was the warmest first month on record worldwide — 1.53 degrees above normal. It was the first time since record-keeping began in 1880 that the globe's average temperature has been so far above the norm for any month of the year.
 
And as 2007 drew to a close, it was also shaping up to be the hottest year on record in the Northern Hemisphere.
