Ice Melt Linked to Accelerated Regional Freshwater Depletion!
Seven of the regions that dominate global ice mass losses are melting at an accelerated rate, a new study shows, and the quickened melt rate is depleting freshwater resources that millions of people depend on.
The impact of melting ice in Greenland and Antarctica on the world's oceans is well documented. But the largest contributors to sea level rise in the 20th century were melting ice caps and glaciers located in seven other regions: Alaska, the Canadian Arctic Archipelago, the Southern Andes, High Mountain Asia, the Russian Arctic, Iceland and the Norwegian archipelago Svalbard. The five Arctic regions accounted for the greatest share of ice loss.
And this ice melt is accelerating, potentially affecting not just coastlines but agriculture and drinking water supplies in communities around the world, according to the study by scientists at NASA's Jet Propulsion Laboratory; the University of California, Irvine; and the National Center for Atmospheric Research in Boulder, Colorado. The study was led by Enrico Ciraci, a UCI graduate student researcher in Earth system science.
"In the Andes Mountains in South America and in High Mountain Asia, glacier melt is a major source of drinking water and irrigation for several hundred million people," said study coauthor Isabella Velicogna, a senior scientist at JPL and professor of Earth system science at UCI. "Stress on this resource could have far-reaching effects on economic activity and political stability."
