The frozen zone is located north of Greenland. Although the ice sheet grows and shrinks seasonally, much of the region’s Arctic sea ice is thought to be thick enough to last through a warm summer.

However, during the summer of 2020, the Wandel Sea east of the Arctic’s Last Ice Area has lost 50 percent of its top layer ice.
In the new study, the researchers found that weather conditions contributed to the shrinking of the thick ice sheet in the Arctic Last Ice Area.
However, climate change is seen as more likely to happen gradually, thinning the ice that has been around for a long time Last Ice Area it from year to year.
This condition suggests that global warming, as a result of climate change, can threaten the region more than previously predicted by climate models.
As climate change melts other areas of the Arctic, it could create problems for animals that depend on ice for breeding, hunting and foraging.
“The Last Ice Area has been considered a sanctuary for future ice-dependent species,” said study author Kristin Laidre, principal investigator at the Center for Polar Science and assistant professor at the University of Washington (UW) School of Aquatic and Fisheries Sciences. Science, Sunday (4/7/2021).
Region Last Ice Area stretches over 2,000 km, stretching from the northern coast of Greenland to the western part of the Canadian Arctic Islands.
In these regions, Arctic sea ice is usually at least 5 years old, with an ice sheet thickness of about 13 feet or about 4 meters.
