Melting the ice slows the circulation system of the Atlantic ocean

In consequence, instead of on warm and damp weather of Western Europe can come cold and drought, if we cease to receive water from the tropics.

According to a new UN report, the unprecedented melting of Arctic and Antarctic ice blocks in combination with the warming of water in the ocean can cause sea-level rise by the end of the century almost a meter (0,91 cm). Talking about the slowdown of the Atlantic meridional circulation (AMC) — this system moves huge masses of water from the North to the South Atlantic, and mixing deep and surface water, reported the online edition of the Chronicle.info with reference to zn.ua.

Speed AMC depends on the balance of salt and fresh water. As soon as the ice sheets of Greenland and Antarctica are melting, the ocean receives more fresh water. This leads to a slowdown AMC. According to climatologists, in 2018, the circulation rate was the slowest for the last 1600 years.

Since AMC is responsible for the stability of the weather, its slowdown will have serious consequences. For example, when this happens, Europe could become colder and drier weather, and the tropics may experience more intense hurricanes.

In West Africa it is expected the deficit of precipitation, and the subtropics — a surplus of heat, favorable for the formation of hurricanes. In addition, it would threaten the marine food chain, which depend on the removal of nutrients from the depths to the surface.

According to experts, as global warming AMC are unlikely to stop in the near future. However, it needs almost instantaneously double the concentration of carbon dioxide in the atmosphere. Scientists warn that to prepare for the consequences now.

Previously, scientists University of Alaska in Fairbanks said that permafrost in the canadian Arctic began to melt at 70 years before the projected date. This means that the global climate crisis occurs much faster than expected by the researchers.

Last year researchers recorded a record warm winter in the Arctic. It is noted that the average temperature Oct-March in the region is -20 degrees Celsius. In the same year, on 20 February, the temperature never dropped below 0. Moreover, on February 24 at the northernmost point of Greenland the temperature reached 6 degrees Celsius. As the researchers note in the February temperature in the Arctic was higher than in Europe.
