Why in news
A study published in Nature Climate Change warns that over 100 glaciers in the European Alps are expected to disappear by 2033 due to human-caused global heating.
Background
The study analyzed satellite data and models to estimate glacier extinction rates under various temperature rise scenarios. It predicts over 800 glaciers will disappear annually in the western US and Canada by 2033.
