Last month was the warmest September in the history of observations – Weather –

This year, three record-breaking months have been registered – January, May and now also September, but June and April of this year were close to setting new records.

Since January, air temperatures have been close to those recorded in 2016, the hottest observation in history to date.

“Currently, there is little difference between 2020 and 2016,” a C3S spokeswoman told AFP.

In the 12 months to September, global temperatures were almost 1.3 degrees Celsius higher than before the Industrial Revolution, which is alarmingly close to 1.5 degrees, the threshold set by the Intergovernmental Panel on Climate Change (IPCC) above which , the severe effects of climate change will be felt.

The long-term goal of the Paris Agreement is to reduce greenhouse gas emissions so as to keep global warming well below two degrees Celsius compared to pre-industrial levels, while at the same time working to limit global temperature rise to 1.5 degrees.

So far, the Earth has warmed by an average of one degree, which is enough to increase the intensity of lethal heat waves, droughts and tropical storms.

However, climate change has been accelerating in recent decades.

19 of the last 20 years are the warmest, since the end of the 19th century accurate meteorological measurements began.

Global temperatures have risen by 0.2 degrees Celsius every decade since the late 1970s, according to EU data.

Air temperatures last month were particularly high in Siberia, where, as elsewhere beyond the Arctic Circle, the last months have been particularly warm.

September was also very hot in the Middle East. New heat records were set in Turkey, Israel and Jordan.

Glow also prevailed in North Africa and Tibet in September, but in the Los Angeles area, the bar of the air thermometer rose to 49 degrees Celsius.

“September was 0.05 degrees Celsius warmer than September 2019, the previous warmest September,” C3S reported.

Last month’s heat records are particularly striking given the cooling effect of the global natural phenomenon of La Ninja in the Pacific.

Meanwhile, the ice sheet in the Arctic Ocean shrank to its second lowest level in September, falling below four million square kilometers for the second time since satellite imagery began in 1978, the C3S said.

Climate change has also disrupted regional weather patterns, causing the sun to heat up the Greenland ice sheet, which is melting faster than the last 12,000 years, according to a study released last week.
