The average temperature in 2019 was only a few hundredths of a degree below the 2016 level.
The last five years have been the hottest on record, and the period of 2010-2019 was the hottest decade since records began, C3S said. Globally temperatures in 2019 were 0.6 Celsius warmer than the 1981-2010 average. Earth’s temperature over the last five years was 1.1-1.2°C warmer than pre-industrial times.
