Americans just lived through the hottest 12 months ever recorded, the National Oceanic and Atmospheric Administration reported Tuesday.

The announcement came as NOAA reported that the U.S. also just experienced its
third-warmest April on record. 

"These temperatures, when added with the first quarter and previous 11 months, calculate to the warmest year-to-date and 12-month periods since recordkeeping began in 1895," the agency reported.

I'm sure there's a perfectly good explanation for all this...although none springs to mind.
