2019 was the second hottest year on record, concluding the hottest decade, European Copernicus climate change service announced on Wednesday. The past year ranks second, just 0.04 ° C behind 2016, which remains the hottest year, but marked by a particularly intense El Niño episode, seasonal equatorial warm current of the Pacific. According to NASA, in 2016, this exceptional El Niño had increased the global temperature by 0.2 ° C.
The hottest five years have all occurred in the past five years, where mercury has risen between 1.1 and 1.2 ° C above the temperature of the pre-industrial era, Copernicus said in a statement. The decade 2010-2019 was also the warmest since the measures began. In 2019, the temperature reached 0.6 ° C higher than the average for the period 1981-2010.
Europe recorded its highest temperature last year, just ahead of 2014, 2015 and 2018. The service also confirms that CO2 concentrations in the atmosphere continued to increase in 2019.
