The warming influence of the intense 2015 - 2016 El Niño event is waning, but May 2016 was still the planet's warmest May since record keeping began in 1880, said NOAA's National Centers for Environmental Information (NCEI) on Thursday. In the NOAA database, May 2016 came in 0.87°C (1.57°F) warmer than the 20th-century average for May, beating the previous record for May, set in 2015, by 0.02°C. This is the smallest margin the monthly global temperature has broken a record by since August 2015...

The impressive global warmth in recent months is due to the steady build-up of heat-trapping greenhouse gases due to human activities, plus a spike due to a large amount of heat being released from waters in the Eastern Pacific due to the powerful 2015-16 El Niño event
