United Nations weather agency has said that the last three years were the hottest on record, underscoring the dramatic warming of the planet.
World Meteorological Organization said, consolidated data from five leading international weather agencies shows that 2015, 2016 and 2017 have been confirmed as the three warmest years on record.
It said 2016 remains the hottest year ever measured due to the warming effect of El Nino, while 2017 was the warmest non-El Nino year.
