300 polar bears, who have been hiding from people for 200 years, live where it seemed would, they cannot survive.

Scientists have discovered a new subpopulation of about 300 polar bears in southeast Greenland. They live where there is practically no sea ice necessary for animals to hunt. Instead, the bears use pieces of ice that have broken off from the glacier. Therefore, scientists called their habitat, it would seem unsuitable for their life, but it turned out that this was not so, according to Live Science.

A secret population of polar bears that could not be discovered for about 200 years, because they were considered part of another population of these animals in Greenland, turned out to be a completely new subpopulation of the largest land predators on Earth.

These bears, which, according to scientists, are about 300 individuals, but the exact number has not yet been established, live on steep slopes around fjords. These are coastal bays where Greenland's glaciers meet the ocean.

“In this area, in the southeast of Greenland, there is practically no sea ice that bears could use to hunt for marine life, so they use ice floes that break away from the glacier to help them survive in conditions of global warming,” says Christine Leidre from the University of Washington.

Before this discovery, scientists knew about the existence of 19 subpopulations of polar bears. But when they decided to study the population of these animals that live in the east of Greenland, they found that the group of bears, which was considered a single entity, consists of two different populations. This new polar bear subpopulation, the 20th in a row, is genetically distinct and lives in isolation, scientists say.

Now polar bears are an endangered species. Today, approximately 36 thousand individuals of these predators remain in the wild. Some scientists believe that polar bears due to global warming may disappear as a species by the end of the 21st century.

Shrinking sea ice in the Arctic is making life difficult for most polar bears, scientists say. After all, there are not so many places where they can use ice floes from the glacier for hunting.

Of course, the amount of sea ice has also decreased in the summer season, and polar bears are adapted to survive without food from 100 to 180 days. But now the sea ice melts earlier and freezes later, which means this situation puts these predators on the brink of survival.

In southeast Greenland, a new subpopulation of polar bears has adapted to life without much sea ice, scientists say. Nevertheless, the difficult local terrain does not allow for too free movement from place to place, and therefore local polar bears are looking for mating partners for a long time. Scientists believe this causes the birth rate in this population to be much lower than in neighboring groups in other parts of Greenland.

“This small group of polar bears cannot be evidence that all bears can survive in a changing climate. The amount of sea ice is drastically decreasing, not everywhere bears have the opportunity to use ice with glacier for hunting. This means that the survival rate of polar bears will continue to decline if the level of global temperature is higher,” says Leidre.

Focus has already written about what scientists have recorded in Unusual warming in the Arctic. The average temperature in the Barents Sea area rises by almost 3 degrees every 10 years.
