The World Meteorological Organization (WMO) announced Tuesday that the average global temperature in May was the warmest of any May on record.

    May, 2016 registered 0.95 degrees Celsius above the May average, according to the WMO's website. The warm temperatures have been most pronounced over the northern hemisphere. This has caused abnormally early melting of Arctic ice and "exceptionally low" snow cover over the Arctic. 

    David Carlson, director of the World Climate Research Programme, told the WMO "Exceptionally high temperatures. Ice melt rates in March and May that we don't normally see until July. Once-in-a-generation rainfall events. The super El Nino is only partly to blame. Abnormal is the new normal." Four of the greatest departures from average have occurred during the last six months, according to data from National Oceanic and Atmospheric Administration.
