NASA warned this week that one of the biggest glaciers of Greenland (Denmark) is it is melting at a “fast” speed, which will have consequences that will be felt for decades to come.
This is the glacier Zachariae Isstrom, which alone collects about 5% of ice covering the island (corresponding to 91 780 square kilometers) and has been reclassified from the “glaciológicamente stable” position that was granted in 2012 to “expedited removal”.
In a study funded by NASA and published this week in the regista Science , the researchers found that Zachariae Isstrom is pouring 5,000 million tons of annual ice mass of the Atlantic Ocean.
If the ice were to melt completely, have the capacity, alone to raise sea levels worldwide more than 46 centimeters.
“The northern Greenland glaciers are changing rapidly. The shape and dynamics of Zachariae Isstrom have changed dramatically in recent years, “explained the co-author and researcher at the University of California, Irvine, Jeremie Mouginot.
“The glacier is disintegrating and releasing large volumes of icebergs into the ocean, which will mean that sea levels will rise in the coming decades,” he said.
Along with Zachariae Isstrom is another great glacier, Nioghalvfjerdsfjorden, also is melting so fast, and they collect about 12% of the mass of ice in Greenland, so, if the two disintegrate completely, the sea levels worldwide would rise about a meter.
