The late heat wave in the middle of October adds to an already very hot spring and summer drought. What are the consequences ?

2022 goesbecome the year that symbolizes global warming? In each season, there is the impression that there are no more as the heat waves follow one another. But why does the heat persist? A depression located on the Atlantic causes winds which bring up the hot air coming from the Sahara. “The air that is currently rising from the Sahara on the one hand is rising much higher than usual, that’s why it is reaching France, but on the other hand it is an air that is also warmer than usual”explains Peter Huatforecaster Weather Solutions.

In many areas there is also a rainfall deficit. In the Alpes-Maritimes, the Lac du Broc now looks like a desert. He loses 4cm per day of its water level. In Toulouse (Upper Garonne)the pillars of a bridge are no longer covered with water. The rare rains are not enough to raise the level of the Garonne. Temperatures are rising without exceeding the projections of climatologists. On the other hand, global warming could accelerate on the horizon 2100.
