Tien Shan glaciers are projected to lose around one-third of their 2020 ice mass before 2040, and 69-93% by 2100, depending on the climate scenario. By the late 21stC, the probability of unmet water demand in summer will increase substantially agupubs.onlinelibrary.wiley.com/doi/10.1029/...

La fonte des glaciers impactera jusqu’à la Belgique
Bonne nouvelle : on peut encore sauver une grande partie des glaciers. Si le réchauffement climatique est limité à 1,5 °C par rapport aux valeurs préindustrielles, comme le prévoit l’accord de Paris, il est possible de préserver plus de la moitié de la masse des glaciers dans le monde. En revanche, si l’on reste sur la trajectoire empruntée par les politiques climatiques actuelles et menant à environ 2,7 °C de réchauffement, seul un peu plus d’un quart subsistera. C’est l’une des conclusions d’une très vaste étude, menée par une équipe internationale de 25 chercheurs s’appuyant sur l’utilisation de pas moins de huit modèles différents. Ce qui rend cette étude particulièrement remarquable, c’est qu’elle s’intéresse à l’évolution des glaciers sur le long terme.
