2020 has registered three record months of heat so far: January, May and September – AFP / Archives
Last month was the warmest September on record in the world, the European program Copernicus, the climate change service, announced on Wednesday, indicating that 2020 could be the warmest year in history, surpassing 2016.
The 12-month period between October 2019 and September 2020 is 1.28 ° C above average temperatures in the pre-industrial era.
Taking into account that the last five years have been the hottest in history, the data brings the planet closer to the 1.5 ° C limit, the target of the Paris Agreement.
The pact, signed in 2015 and in which almost 200 states have pledged to reduce their greenhouse gas emissions, aims to keep global warming below 1.5ºC, a maximum of 2 ° C, to limit the impact of increasingly devastating storms, droughts and other extreme events.
The planet’s temperature has already increased by more than 1 ° C and has increased by an average of 0.2 ° C per decade since the late 1970s, highlights the Copernicus program in its monthly climate balance.
And 2020 will not change the trend as it also records the warmest January, May and June months on record.
“Worldwide, September 2020 was 0.05 ° C above September 2019, the hottest month on record so far,” says the European service. This means 0.63 ° C above the average for the period 1981-2020.
Temperatures were especially high in Siberia, following the trend of a heat wave that started in spring (northern hemisphere) and favored a series of large fires.
– Arctic heat –
The heat was also above normal in the Arctic Ocean, the program highlights, recalling that this year the Arctic ice sheet ended the summer with the second smallest area in history, after that registered in 2012.
“The combination of record temperatures and reduced ice in 2020 highlights the importance of improving control in a region with a faster temperature rise than the rest of the world,” says Carlo Buontempo, director of the European program on climate change.
And the Great North was not the only area affected.
North America had a very hot September, especially with 49 ° C earlier this month in Los Angeles County, in a California ravaged by fires.
In addition to September, data from European satellites show that the period from January to September 2020 is warmer than the same period in 2019, the second year with the highest temperatures.
The analysis compares the nine months of 2020 and 2016, the hottest year in history, and reveals “quite similar” anomalies, according to Copernicus. But climatic phenomena such as the current development of La Niña, which tends to reduce global temperature, “will influence the probability that 2020 will become the warmest year in history.”
“There are three months left, during which anything can happen,” Freja Vamborg, a Copernicus scientist, told AFP, before recalling that the agency “does not make predictions about world temperatures.”
The Copernicus satellite database for observing temperatures begins in 1979, but conventional terrestrial data and information from other agencies do not show any years with higher temperatures before 1979, since the pre-industrial era.
