Climate, Copernicus raises the alarm: 2023 will be the hottest year in history

From January to November, the global average temperature was 0.13°C higher than the previous record set in 2016

2023 is on track to become the hottest year in Earth’s history. This was announced by the European climate monitoring service Copernicus, explaining that from January to November, the global average temperature was 1.46°C higher than the pre-industrial average of the period 1850-1900 and 0.13°C higher than the eleven-month average of 2016currently becoming the warmest calendar year on record.

“2023 now has six months and two record-breaking seasons. This extraordinary November means that 2023 will be the warmest year in recorded history,” said Samantha Burgess, Deputy Head of the Copernicus Climate Change Bureau (C3S).

Furthermore, the director of C3S, Carlo Buontempo, adds: “As long as greenhouse gas concentrations continue to increase we cannot expect different results from those seen this year. Temperatures will continue to rise, as will the impacts of heat waves and droughts.”

Record temperatures in November

According to the data, November 2023 was the warmest November on record globally, with an average surface air temperature of 14.22°C, 0.85°C above the 1991-2020 average and 0.32°C above the temperature of the previous warmest November, in 2020. The anomaly of global temperature for November 2023 was equal to that of October 2023 and only lower than the September 2023 anomaly of 0.93°C. November 2023 was about 1.75°C warmer than an estimate of the November average for 1850-1900, the designated pre-industrial reference period.

The average sea surface temperature for November 2023 was the highest on record for November, 0.25°C warmer than the second warmest November in 2015.

Hot autumn

Autumn, September-November 2023, was the warmest on record globally by a wide margin, with an average temperature of 15.30°C, which is 0.88°C above average.

The European average temperature in the period September-November 2023 was 10.96°C, which is 1.43°C above average. This made the autumn of 2023 the second warmest on record, just 0.03°C colder than autumn 2020.
