The year 2023 will be the hottest in history after an “extraordinary” November which became the sixth month in a row to break records, the European Copernicus service said on Wednesday, in the midst of climate negotiations at COP28. The past month, with an average of 14.22°C on the global surface, exceeds the previous record of November 2020 by 0.32°C. 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 (September to November in the northern hemisphere) is thus the hottest in history, with 15.3°C, a wide margin of 0.88°C above averages. 2023 now has six months and two record seasons.

This extraordinary month of November, which notably includes two days with temperatures higher than 2 degrees in the pre-industrial era, means 2023 is the hottest year ever recorded in history, Samantha Burgess, deputy head of Copernicus' Climate Change Service (C3S), said in a statement .
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 over the first eleven months of 2016, the hottest year yet.
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 rise, as will the effects of heat waves and droughts, warned Carlo Buontempo, director of C3S, quoted in the press release.
The cyclical climatic phenomenon El Niño, above the Pacific, continues to fuel the rise in temperatures in 2023 but has not yet reached its peak.
In November 2023, the ocean surface temperature is also the warmest for this time of year, 0.25°C warmer than the previous peak in November 2015. This new heat record is ;adds to those already beaten each month since April.
The extent of the Arctic sea ice, to the north, records its 8th monthly low for November, 4% below averages. In the Antarctic, a second lowest level for the month of November was recorded, 9% below the average, says Copernicus.
Drought continued last month in several regions of the United States, Central and Eastern Asia, and is particularly pronounced in South America. On the other hand, Europe was wetter, in the wake of storm Ciaran which caused significant rainfall.
