“September 2023 was the warmest September ever recorded globally” and broke the previous record by an impressive margin, continuing the streak of global monthly records that began in June, the European Copernicus Observatory announced today.

With the average global surface temperature reaching 16.38°C, last month was an “unprecedented anomaly”, surpassing the previous record set in September 2020 by 0.5°C.

September 2023 is “1.75°C warmer than the average September in the period 1850-1900”, the pre-industrial reference period, before human-made greenhouse effect started, according to the climate change service Copernicus (C3S).

Last month was a full degree Celsius warmer than the period from 1991 to 2020.

2023 is also on track to be the warmest year on record. The temperature this year is on track to be 1.4°C above the pre-industrial average.

In other words, it will be just 0.1°C below the target of the Paris climate agreement, which aimed to limit temperature rise to 1.5°C by the end of the century.

“Two months before COP28,” the UN’s global climate summit, “the sense of urgency to take ambitious climate action has never been more critical,” said Samantha Burgess, deputy director of C3S, according to press release released by the European agency.
