Global warming is shrinking glaciers faster than thought

Glaciers could disappear from several mountain ranges during this century, new report says

Global warming is melting the world's glaciers and caused sea levels to rise by more than an INCH

The melting, a result of global warming, is adding to rising sea levels, according to the study. That's far more than previous studies, which Zemp said relied on data from around 500 glaciers.

Based on their findings, the authors suggest that glaciers could nearly disappear in some mountain ranges by 2100 (including the Caucasus, Central Europe, Western Canada and the United States of America and New Zealand).

Melting glaciers in Russia's Arctic territory. This image, recorded by the Sentinel-2 satellite in 2017, shows the blue glaciers on the reddish-brown Franz Josef Land archipelago in the Arctic Ocean (black). This allowed the researchers to reconstruct changes in the ice thickness of more than 19,000 glaciers worldwide. This ice loss of all glaciers roughly corresponds to the mass loss of Greenland's Ice Sheet, and clearly exceeds that of the Antarctic.

Researchers were then able to spot ice thickness changes to more than 190,000 glaciers around the world.

Alaska glaciers were the largest contributors, followed by melting ice fields in Patagonia and glaciers in the Arctic regions.

The map below, developed by the European Space Agency, illustrates where this ice loss has occurred.

"By combining these two measurement methods and having the new comprehensive dataset, we can estimate how much ice has been lost each year in all mountain regions since the 1960s", says Michael Zemp of the University of Zurich, who led the study.

Global mass loss of glacier ice has increased significantly in the last 30 years and narrowed it down to a ten year window spanning from 2006 to 2016.

The global mass loss of glacier ice has increased significantly in the last 30 years and now amounts to 335 billion tons of lost ice each year.

The loss led to a 27-millimeter increase in global sea levels over this period, researchers found.

"Globally, we lose about three times the ice volume stored in the entirety of the European Alps-every single year!" They published their report Monday in the journal Nature. This translates into an increase in sea levels of almost 1 millimeter per year, according to the calculations.
