Glacier Disappearance

Context: A new study published in Nature Climate Change projects that global glacier disappearance will peak around mid-century, with up to 4,000 glaciers vanishing annually under high-warming scenarios. About Glacier Disappearance: What it is? Glacier disappearance refers to the complete extinction of individual glaciers when their area falls below 0.01 sq km or their remaining …
