With an average of 14.22°C on the surface of the globe, the past month exceeds the previous record of November 2020 by 0.32°C. The month of November 2023 is also 1.75°C warmer than the average November for the period 1850-1900, which corresponds to the pre-industrial era.
The boreal autumn (in the northern hemisphere) is thus the hottest in history “by a wide margin”, since it is 0.88°C above average, according to Copernicus.
“The temperature will continue to rise”
“2023 now has six months and two record-breaking seasons. This extraordinary November, including two days with temperatures 2 degrees higher than pre-industrial times, means 2023 is the hottest year ever recorded in history,” said Samantha Burgess, deputy head of the service. Climate Change (C3S) of Copernicus, in a press release.
Since January, the average temperature has been the hottest ever measured over the first eleven months of the year: 1.46°C above the climate average for the period 1850-1900, and 0.13°C above over the first eleven months of 2016, the hottest year yet.
This shows how uncomfortably close the world is to 1.5°C above pre-industrial temperatures for a single year. This threshold is central to the 2015 Paris climate agreement, even if exceeding this limit will require warming at this level over several decades.
“As long as greenhouse gas concentrations continue to increase, we should not expect results different from those observed this year. The temperature will continue to increase, as will the effects of heat waves and droughts,” underlined Carlo Buontempo, director of C3S, quoted in the press release. “Reaching net zero (in terms of emissions) as soon as possible is an effective way to manage climate-related risks,” he added, in a barely veiled allusion to the climate negotiations underway at COP28. .
