a France at 50 degrees, what can that look like?

The ones he shows us are saturated with red.

Here is, according to his forecasts, what awaits France in 2050: 3 degrees more than current averages “in a large south-eastern quarter“or even 3.5 degrees in mountain areas,”which heat up even faster than lowland areas“The areas that warm the least, such as the north of the country, still gain 2 degrees.

“Two degrees is the warming we have experienced in France since the pre-industrial era. Two degrees is the melting of almost all the glaciers in the Pyrenees.”

“Special Envoy” imagined it, this south of France in June 2050, made unlivable by the rise in temperatures. A burning desert with the air of the Far West, without even the freshness of sea bathing: in waters that have become warmer, all invasive species, such as jellyfish, will have proliferated …
