The year 2016 has been confirmed as the hottest year on record, surpassing the exceptionally high temperatures of 2015, according to a consolidated analysis by the World Meteorological Organization (WMO).
The globally averaged temperature in 2016 was about 1.1°C higher than the pre-industrial period. It was approximately 0.83° Celsius above the long term average (14°C) of the WMO 1961-1990 reference period, and about 0.07°C warmer than the previous record set in 2015.
WMO uses data from the US National Oceanic and Atmospheric Administration, NASA’s Goddard Institute for Space Studies and the UK’s Met Office Hadley Centre and the University of East Anglia’s Climatic Research Unit. WMO also draws on reanalysis data from the European Centre for Medium Range Weather Forecasts and the Copernicus Climate Change Service, which use a weather forecasting system to combine many sources of data to provide a more complete picture of global temperatures, including in Polar regions.
