July of 2012 – officially the hottest month in over 100 years

The average temperature across the U.S. is 77.6 degrees which is three degrees above average. The warm July helped make the last 12 months the hottest ever experienced since record keeping began in 1895. The record breaking weather is taking a toll on the country’s farmland and states along the Mississippi River are enduring one of the worst droughts to hit the United States in half a century.
