2012 was officially warmest on record in US

Last year was the warmest on record in the United States and the second most extreme for droughts, wildfires, hurricanes, and storms, according to a report from the National Oceanic and Atmospheric Administration.

A brutal combination of a widespread drought and a mostly absent winter pushed the average annual US temperature last year up to 55.32 degrees Fahrenheit. That’s a full degree warmer than the old record set in 1998.
