We broke the record. Again.
Last month was the hottest May on record, and the past five months were the warmest start to a year on record, according to new data released by the National Oceanic and Atmospheric Administration. It's a continuation of trends that made 2014 the most blistering year for the surface of the planet, in records going back to 1880.
The animation below shows the Earth’s warming climate, recorded in monthly measurements from land and sea over more than 135 years. Temperatures are displayed in degrees above or below the 20th-century average. Thirteen of the 14 hottest years are in the 21st century, and 2015 is on track to break the heat record again. It isn't even close.
This Year Is Headed for the Hottest on Record, by a Long Shot
