Consolidated data from five leading international weather agencies shows that "2015, 2016 and 2017 have been confirmed as the three warmest years on record", the World Meteorological Organisation (WMO) said.
It 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.
"The long-term temperature trend is far more important than the ranking of individual years, and that trend is an upward one," WMO secretary-general Petteri Taalas said in a statement.
The 21st century has so far been a period of the hottest weather, accounting for 17 of the 18 warmest years on record.
"And the degree of warming during the past three years has been exceptional," Tasslas added. The WMO also highlighted the intensification of weather and climate related disasters, which hit record levels in the United States last year, while multiple countries were devastated by cyclones, floods and drought. more
