Huge holes in the ice of the North Ocean!

The Arctic Ocean, the sea of ​​ice, is the northern polar region of the earth. The role of this region in keeping the climate normal is unmatched. As the Earth’s temperature continues to rise, the risk of the polar region is constantly increasing.

However, new information has come out in the observation of scientists. The largest hole in history was discovered in the Arctic Sea in 2020. This was observed in May last year in an area of ​​the Arctic where the ice is the oldest and thickest and melting of this thousand year old ice is giving a new forecast of disaster.

If there is water in an empty part of an ice-covered area, that area is called polynia. This polynia was first seen on the island of Elsmer in the Arctic. A report was released in August. Where it was said that between 197 and 2004 many large polynia were found in the same place.

Kent Murray, the report’s lead researcher, said it was difficult to remove ice from the island in the north, because the area was much thicker. Researchers at the University of Toronto-Mississauga say they have never seen such a large polynia in the region.

The island’s sea ice is 13 feet thick and has been frozen for at least 5 years, on the north coast of Alesmer. But as global warming continues, the Arctic has not been able to hold ice for as long as it used to. By the summer of 2020, the Wandel Sea had lost more than half of its ice before the Arctic.

Another 2021 study found that the part of the ice that connects the Arctic Ocean to Greenland is taking time to form, and is melting faster each year.

Scientists say that by the end of this century, the ice in the Arctic Ocean will melt completely in the summer. It will be difficult for marine seals and white bears, which depend on sea ice, to survive.

If there is a storm or strong wind in the sea then it causes cracks in the thick ice of the sea or it becomes water. This can also cause polyneuria in the ice layer.

In May 2020, there was a storm on Elesmere Island. According to satellite data, small cracks appeared on the ice on May 14 and on May 15 it turned into a large polynia, which is 100 km long and 30 km wide.

Scientists say that in the very near future, Polynesia will appear again and again in the Arctic ice. The ecosystems of seabirds, marine fish, seals or polar bears, all polar animals will be threatened. The sea water and the surrounding air will become so hot that marine life will not be able to survive. The world’s climate will lose its balance.
