0 20

This end of the year is milder than normal for the season. The peak of sweetness is expected on December 31st. The transition to 2023 will take place under the sign of climate change, after twelve months characterized by strong anomalies.

The temperature anomalies were connected during 2022. We still remember this exceptionally dry summer, with intense heat, while temperature records were tied. Then it was autumn’s turn which was too mild compared to seasonal norms. Now, it’s the temperatures this holiday season that are anything but normal.

Meteo France confirm it : this end of the year is characterized by record sweetness. This will continue until the end, as a peak of mildness is expected for this 31 December 2022. The thermal excess (ie the number of degrees above normal) will reach +8 degrees, d’ after Météo-France.

« This New Year’s Eve should be the sweetest that has ever been observed throughout the country (an archive that starts in 1947) to symbolically close an exceptionally sweet year 2022 “says the service. It should also enter the top 5 of the mildest days recorded in December in France. And finally, this disparity of +8 degrees could also be one of the biggest heat anomalies ever recorded in any month.

Only in Nice, the so-called “tropical” nights, above 20 degrees, accumulate at the end of the year. In Corsica, the sweetness ends in the year 2022 which just happens to be the hottest year ever recorded on the island, maybe even before 2003. This year-end anomaly is not exclusive to France: Europe is concerned with temperatures well above normal for the season. across much of the continent.

This end of the year is still a reminder of climate change

Yes, this extreme sweetness is largely linked to climate change. The latter increases the amplitude of a natural phenomenon. ” Human influence makes classic extreme hot dynamic weather “, reminds climatologist Christophe Cassou on Twitter.

Climate change, due to human activities, is indeed increasing the magnitude and frequency of weather anomalies. Record peaks (both hot and cold for that matter) like extreme events are increasingly concentrated in the 21st century, where they were previously rarer and more distant.

« This wave of exceptional winter sweetness is consistent with climate change “, confirms Météo-France on its site. ” The rarefaction of cold spells is a marker of climate change: the last cold spell across the country dates back to February 2012…almost 10 years ago. On the other hand, the early peaks of sweetness or heat are more frequent. »
