Last month was september more warm in the world since records have been kept by an “extraordinary” marginthe European Union (EU) climate monitor, Copernicus, reported on Thursday.

Much of the world endured unusually warm temperatures in September, in a year that is projected as the warmest in history and in which the northern hemisphere faced its hottest summer.

The average temperature of September, of 16.38º centigrade on the planet’s surface, “broke records by an extraordinary amount,” said Samantha Burgess, deputy director of the Copernicus Climate Change Service (C3S).

According to a Copernicus report, the average temperature in September was 0.93ºC above the 1991-2020 average for that month and 0.5ºC above the previous record, in 2020.

Record temperatures are usually broken by much smaller margins, of 0.1ºC.

The report noted that last September was about 1.75ºC warmer than the average for the month in the pre-industrial period, from 1850 to 1900.

We have gone through the most incredible September from a climatic point of view. It can not be believed“, he declared to the AFP Carlo Buontempo, director of C3S.

“Climate change is not something that will happen in 10 years. Climate change is here”he added.

warmest year

The global average temperatures from January to September were 1.4ºC higher than those of the period 1850-1900, close to breaking the 1.5ºC limit as the warming goal of the 2015 Paris Agreement.

This threshold is the most ambitious goal of the pact and is considered essential to avoid the most catastrophic consequences of climate change.

Average global temperatures from January to September were 0.05ºC higher than the same period in 2016, the hottest year on record.

He El Niño phenomenonwhich warms waters in the South Pacific and causes high temperatures in other regions, could make 2023 the warmest year on record in the next three months.

Scientists anticipate that the worst effects of the current El Niño will be felt in late 2023 and early 2024.

Although El Niño influenced the high temperatures of September, “There is no doubt that climate change made it much worse“said Buontempo.

Europe experienced its warmest September on record, with 2.51ºC above the average for 1991-2020 and many countries breaking their national heat records for the month.

The average sea surface temperature, excluding the polar areas, also reached a record for September, of 20.92ºC.

Scientists say warmer sea surfaces due to climate change are making extreme weather events more intense, as seen with Storm Daniel that caused devastating flooding in Libya and Greece in September.

World leaders will gather in Dubai from November 30 for the COP28 climate summit, amid the accelerating consequences of global warming.
