United Nations weather agency, the World Meteorological Organization, WMO has said the last three years were the hottest on record. WMO, Secretary-General, Petteri Taalas said in a statement that consolidated data from five leading international weather agencies shows that 2015, 2016 and 2017 have been confirmed as the three warmest years on record. <br/><br/>The statement said the long-term temperature trend is far more important than the ranking of individual years, and that trend is an upward one. The statement added that 2016 remains the hottest year ever measured, due to the warming effect of El Nino, while 2017 was the warmest non-El Nino year beating out 2015 by less than one-hundredth of a degree.<br/>'<br/> The WMO findings were based on data provided by the US National Oceanic and Atmospheric Administration, NASA, Britain's Met office, the European Centre for medium range weather forecasts and the Japan Meteorological Agency. <br/>
