July was the hottest month in America ever recorded.



In 118 years of U.S. records, July 2012 stands as king, hotter than any month previously observed. NOAA reports today that the average temperature across the continental U.S. was 3.3 degrees Fahrenheit warmer than the 20th century average, 0.2 degrees hotter than the previous record set in July, 1936.

Not only was the month of July unrivaled for its hot temperatures across the nation, but so too were the first seven months of the calendar year and the last 12 months. In fact, the last four 12-month periods have each successively established new records for the warmest period of that length.
