Advances in satellite technology have revealed that the world’s glaciers contain significantly less ice than previously thought, according to a study published in Nature Geoscience on Monday. The revised estimate reduces global sea level rise by 3 inches if all glaciers were to melt. But it raises concern for some communities that rely on seasonal melt from glaciers to feed rivers and irrigate crops. If glaciers contain less ice, water will run out sooner than expected.
