Ahead of Cop 26 on the climate, a new study shows the impact of rising sea levels. It would threaten at least 500 million people around the world.
If the temperature were to increase by 4 ° C, Bordeaux (Gironde) would experience a rise in water levels according to a new study. In Anglet (Pyrénées-Atlantiques), some areas could completely disappear under water in several decades in the event of global warming, such as the Cavaliers district.
These projections were made by scientists to better show the extent of global warming. These are scenarios that make residents of areas affected by a potential rise in water reflect, such as in the city of Anglet. “It inspires some concern for generations to come (…) if there is something to do, it is now”, estimates one inhabitant. Even if humanity manages to limit global warming to 1.5 ° C, the researchers say, 500 million people will still live in a flooded city.
