World Meteorological Organization (WMO) stated about the warmest decade and a record 2020 because of climate change due to anthropogenic impact.
Europe’s Copernicus Climate Change Service (C3S) today said that globally 2020 was tied with 2016 as the warmest year on record. Europe saw its warmest year on record, 0.4°C warmer than 2019 which was previously the warmest year. There was extraordinary heat in the Arctic and Siberia, contributing to exceptional wildfires and low sea ice.
Another negative trend — CO2 concentrations in the atmosphere have continued to rise at a rate of approximately 2.3 ppm/year in 2020 reaching a maximum of 413 ppm during May 2020.
It should be noted, that WMO combines data from ECMWF, NASA, NOAA, the UK Met Office, and Japan Meteorological Agency for a consolidated global temperature figure.
