The hottest year ever recorded in Limousin
Last year, the weather again broke records. Average temperatures are the hottest ever recorded across much of France. The whole Limo is worried. This increase in the thermometer is accompanied by a very significant decrease in precipitation.
Winter in Limousine is well established. In the coming days, sub-zero temperatures should surprise car windshields again in the early morning. But don’t worry, these consecutive cold waves are actually a textbook example for meteorologists.
In fact, overall, our winter is quite mild. Because climate change cannot be assessed negative temperature peaks, however of course average weather data accumulated over a long period of time.
Everywhere in Limousin, as in the vast majority of France 2022 was the hottest year It has never been recorded by Météo France, as evidenced by the interactive map. Based on the last thirty years.
Locally, the numbers are very significant. take an example Brive, in Correze. Since 1987, the average temperature for an entire year has never been this high: 15.0°C.
Higher than usual normals (average 13°C) with very little precipitation. In 2022, Brive recorded almost a precipitation deficit 26%.
Overall, cumulative precipitation in Limousin was well below normal, with deficits ranging from 21.9% for the municipality of La Courtine (Creuse) to 39.4% for La Souterraine! An impressive decrease that ranks the La Souterraine sector as the 2nd largest decrease in precipitation in New Aquitaine.
This the observation is generalized for the entire large regionWith the exception of the town of Vendées-Montalive in the Gironde, the hottest year was recorded in 2003 (with a record temperature during the European heat wave in August).
The 2022 climate assessment therefore makes the seasons obsolete and global warming tangible to everyone on a daily basis. After years of questioning, the question is no longer there: climate change is here. The concern today is the consequences of these climate changes.
“The high temperatures we’ve been experiencing were predictable, but they weren’t particularly so for 2022. In the coming years, we can expect temperatures to rise even further because global warming is here to stay.Michel Galliot, climatologist and president of Limousin Nature Environnement, admits.
One of the territories is France most affected with global warming.
If people do not have much difficulty in adapting to extreme temperatures in summer, as in winter, fauna and flora sometimes struggle to resist. Limo views plus a excellent indicator the consequences of these changes.
The summer of 2022 was the hottest summer on record in Europe. During this time, the Limousine was hit by one historic drought. The phenomenon is certainly less visible than the mega-fires that ravaged the Gironde, but it is a real break from normalcy that worries observers. Until last October, Creuse, Corrèze and Haute-Vienne were still located crisis situationthe highest drought warning level.
If the drought phenomenon is not new, the long-term projected scenarios are worrying and clearly predicted. depletion of water resources.
Due to insufficient flow last summer, some municipalities had to adapt to provide water to their constituents. This is the case in the Xaintrie basin, particularly in the applicant municipality of Saint-Privat. tankers to supply the drinking water network daily this summer.
“This is quite dramatic because it becomes repetitive. And above all, it is happening faster and faster, because we are in July, not yet in the middle of the low water of late August – early September “At the beginning of the summer of 2022, the president of the water union, Joël Beylel, explained. All this is a direct result of the particularly low level of the Glane, which in normal times supplies the Xaintrie basin.
What is needed is to change our system.
Michel Galliot, climatologist and president of Limousin Natural Environment
“Today, no one can deny the existence of climate change, but people do not admit that they have a role. They systematically think that it is up to others to make an effort.“, Michel Galliot, climatologist and president of Limousin Nature Environnement.
According to him, it is about realization collective efforts. “We face both natural climate variability and climate change. There are already some adaptations, we are currently taking measures to mitigate the impact somewhat, but we need to change our systems.“.
Therefore, these efforts concern everyone: individuals, communities and states. The latest example: this call to reduce our electricity consumption. For several weeks, the main manager of the network has indicated that he pays with a a significant reduction in consumption.
Is that enough? Nope. All these should be regulated by standards, as they have been lately obligations imposed on lessors of energy-efficient accommodation. To whom on a larger scale, international agreements are also needed for this.
