Scientists told how much it increased the level of the World Ocean




Ученые рассказали, на сколько вырос уровень Мирового океана

In 2018 the destruction of the ice layer took place twice.

Since 1993 global sea level has increased by 77.1 mm or 3.1 mm per year. The reason was global warming that led to the melting of glaciers in Greenland and Antarctica, according to a study by scientists from the meteorological world organization.

The sea level rise threatens the first, island states, states with a long coastline – for example the Netherlands and Nigeria. If the global sea level will rise 200 mm below the water to completely leave the island nation of Tuvu.

Based on the data of the mission and the TOPEX / Poseidon and Argo have developed a model for raising the level of the ocean in the world. As a result, climate scientists came to the conclusion that the increase rises to 0.1 mm each year – the largest contribution to this process was thermal expansion. This is followed by the melting of the glaciers in general and in particular in Greenland and the North Pole.

Previous studies by climate scientists at Yale University have shown a significant – more than twice as high – heating of the warm salty water layers in the Canadian Arctic catchment area. They are located in the bottom layer of the Chukchi sea, but when it reaches the surface, it will melt almost all the enormous amounts of ice.

Recently, it became known that the thickest ice in the Arctic was crumbling as a result of variations in temperature, the opening of water in northern Greenland. In the past, this region was thick, even in summer. The main reason why climatologists call the falling temperatures in the northern hemisphere. The sea off the north coast of Greenland was always frozen, it was called the "last ice area", which can stop the greenhouse effect.

Scientists believe that between the years of 2030 and 2050 during the summer period the ice in the Arctic Ocean will completely disappear.
