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.
NOAA says 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. (Video via NOAA)
