Scientists stated that the climate changes, combined with the effects of the El Niño phenomenon, which warms surface waters in the eastern and central Pacific Ocean, have caused recent record temperatures.

“The unprecedented temperatures for the time of year observed in September — after an atypical summer — broke records in extraordinary numbers. This extreme month set 2023 on track to be the hottest year and around 1,4ºC above pre-industrial average temperatures,” said Samantha Burgess, deputy director of Copernicus, in a statement.
The global temperature from January to September is also 1,4ºC higher than the pre-industrial average (from the 1850s to 1900s), the institute added, as climate change drives global temperatures to new records and weather phenomena from curto term drive temperature movements.
Last month was the warmest September on record globally, 0,93°C above the average temperature for the same month between 1991 and 2020. The monthly global temperature was the most outlier of any year in the ERA5 dataset, which dates back to 1940.

“With two months to go until COP28, the UN climate change conference, the sense of urgency for ambitious climate action has never been more critical,” said Burgess.
Last year was not a record, although the world was 1,2ºC warmer than in the pre-industrial era. The previous record was held in 2016 and 2020, when temperatures were on average 1,25°C higher.
“What is especially worrying is that the El Niño phenomenon is still developing and therefore we can expect these record temperatures to continue for months, with cascading impacts on the environment and society,” said the secretary-general of the Meteorological Organization.
