The National Oceanic and Atmospheric Administration has released their temperature data for the month of May 2016, showing yet more broken temperature records around the globe, fueled in part by a record-breaking El Niño, estimated to have contributed to roughly 20 percent of the observed temperature increase.

May was the thirteenth consecutive month to see the global average temperature come in above the 20th-century average, at 0.87ºC (1.57ºF) above the norm, and as with preceding months, was the hottest month of May on record, breaking the previous record set by May 2015. 2016 is still on track to break the all-time global temperature record set by 2015, and would be the 3rd consecutive year to do so — this effect would be a one-in-ten-thousand fluke if man-made global warming wasn’t a factor, according to the Potsdam Institute for Climate Impact Research’s professor Stefan Rahmstorf.
