glaciers are losing more and more ground and the sea level last an average of almost a Millimeter in the year. This is the conclusion of researchers from the University of Zurich by means of estimates, published in the journal Nature.
the basis for the findings of the Swiss scientists satellite measurements and field observations. The satellites measure the earth’s surface digitally, and provide information on the thickness of the ice at different points in time. According to the authors, they were able to reconstruct the changes in the world, more than 19,000 glaciers and the Eisverlust for all the mountain regions all the way back to the sixties to appreciate it.

All good
Unfortunately, no: a Lot of damage are no longer change. The earth is warming in any case.

As the researchers found out, lost the glacier between 1961 and 2016, more than 9,000 billion tons of ice per year is about 335 billion tons. For the responsible glaciologist Michael Zemp, this Numbers are remarkable. “Worldwide, we are losing at present, around three times the remaining glacier volume in the European Alps, and every year,” he said.
one of the most momentous melting glaciers in Alaska, Patagonia and the North pole
The impact is especially felt by people near the coast. The lost glacier mass is reflected in a global mean rise in sea level of 27 millimeters. According to the Zurich-based researchers, it was only in the years 2006 to 2016, an average of almost a Millimeter a year.

the glaciers in Alaska contributed the most, followed by those in Patagonia in southern Chile and Argentina and in the Arctic glacier regions around the North pole. Also in the Alps, in the Caucasus and in new Zealand, the glaciers have lost a lot of ice cream, even if – due to the relatively small areas with minor impact on the sea level.
Currently, glaciers contribute, according to Zemp and his Team of 25 to 30 percent to the global sea level rise. Another cause is a further consequence of the earth and ocean warming: The sea water is gaining volume.
