RELATEDGlaciers melting faster than scientists expected due to climate change
The world's glaciers are shrinking and disappearing faster than scientists thought, with two-thirds of them projected to melt out of existence by the end of the century at current climate change trends, according to a new study.
But if the world can limit future warming to just a few more tenths of a degree and fulfill international goals — technically possible but unlikely according to many scientists — then slightly less than half the globe's glaciers will disappear, said the same study. Mostly small but well-known glaciers are marching to extinction, study authors said.
In an also unlikely worst-case scenario of several degrees of warming, 83% of the world's glaciers would likely disappear by the year 2100, study authors said.
