America is so cold that sharks have to freeze to death

The United States is experiencing a record cold, so cold that sharks - animals born to bear cold also salute.

In recent days, the United States is experiencing the most severe cold spell in decades. In the North, the temperature has dropped to minus 50 degrees Celsius. America's Midwest and East Coast face a lot of trouble: car accidents and motorbikes because the tubes are frozen, people die network because of shock .

This cold wave broke a lot of US temperature records. And even, it is so cold that sharks - animals that are born to bear cold - must freeze to death.

Sharks die freezing in the US sea.

Specifically, recently journalist James Mullin caught the body of a shark outside Cape Cod Bay.

Mullin immediately contacted the Coastal Research Center in Provincetown, and they discovered an additional corpse of sharks in the same area. After finding out, they discovered that the cause of 2 fatal sharks was "cold shock" - an unbelievable cause.

Be aware, the bodies of the North American sharks contain many substances that help them survive in cold waters. These can be urea and trimethylamine oxides such as Greenland sharks, or AFP (antifreeze Protein) proteins.

In fact, when the organism freezes, the inside of the body will appear ice crystals clinging to the cell, causing the cells to freeze, crumble and die. When there are too many dead cells, the organism cannot live. However, these compounds work to prevent this process, making the cytoplasm more dense, harder to freeze, and frost cannot spread.

Sharks are born to bear cold, but this time also have to give up.

However, these compounds only work at certain temperatures. And the current weather in America has made these two sharks unable to stand it anymore.

Earlier, two bad dogs were found to freeze out in the snow. In Ohio, a deer was trapped in the glacier, and the rescue team was forced to kill the animal to free it from pain.

Cold prices make rivers and streams in the US freeze.

It is known that the cold comes from the cold air in the North , but it is quite unusual because every year is not so cold.

According to meteorological experts, the thermal background is currently 10 - 20 degrees C lower than the same time in 2016. At this temperature, a person's life can be threatened after only 30 minutes out.

Snow-covered streets.

Snow is also falling at a record in the US. In some areas of New York, snowfall is recorded up to 1.5m thick.

Rivers freeze, many events related to annual swimming are canceled because it is too dangerous.

The cause of abnormal cold weather has not been clarified yet! Some people believe that climate change is the cause, or directly related to the phenomenon of La Nina after the end of El Nino.

As expected, this cold spell will last until the beginning of January 2018.
