Last Month Was the Hottest May on Record — Again

Last month was officially the hottest May on record, according to the National Oceanic and Atmospheric Administration.

NOAA tracked temperatures 1.57 degrees Fahrenheit above the worldwide average of 58.6 degrees.

The data indicates 2015 is on pace to be the hottest year on record, with temperatures in the first five months in the surpassing the same period in 2010 as the warmest first five months.

NOAA scientists claim the heat is thanks at least in part to El Nino. The cyclical warming of the eastern Pacific Ocean can lead to what we're seeing now: record temperatures and record rainfall.
