Global warming is particularly alarming in the Arctic, where it occurred in recent decades at a rate three or even four times higher than the rest of the planet, according to the latest scientific studies.

This is one of the illustrations of global warming. Greenland’s huge glacial cap has lost 4,700 billion tonnes in twenty years, contributing to an increase in the oceans of 1.2 centimeters, according to new data published this week by the Polar Portal, organization chaping the Danish institutes on the Arctic.
This fondue ice volume, which at the US area level represents 50 centimeters of water, is particularly important on the coast of the Danish autonomous territory, according to this study based on satellite observations of the Grace program .

“Since the beginning of the measurements in April 2002, Greenland’s Glacial Cap has lost about 4,700 gigatons or 4,700 cubic kilometers,” says Polar Portal. “The data show that the majority of ice loss occurs on the edges of the ice cap, where independent observations show that the ice is shrinking, that the glacial fronts retreat in the fjords and on the ground, and that the cast iron is Stronger on the surface of the ice, “says the Danish organization. The west coast of Greenland is particularly concerned, according to its data.
Acceleration of global warming
Global warming is particularly alarming in the Arctic, where it occurred in recent decades at a rate three or even four times higher than the rest of the planet, according to the latest scientific studies.
According to a study published at the end of January by NASA, the accelerated cast iron near the ribs is explained by the warming of the water of the Arctic Ocean, which contribute “at least as much as air to the surface” The decline of the Greenlandic cap.
The melting of ice in Greenland is currently the main climbing factor of the oceans on earth and the glaciers of the territory now decrease six to seven times faster than twenty-five years ago, according to the American agency.

According to climatologists, Greenland’s Glacial Cap contains in total enough to raise oceans over 7 meters, and Antarctica of nearly 50 meters, although melting processes are very slow phenomena.
At the same time, the Arctic pack ice – on the other hand, does not affect the level of the oceans – also considerably declined, losing an average of 13% of its surface every ten years.
