Beginning in 2050 at the North pole during the summer melting will be almost ice — according to new data from the climate simulation, its area will be less than a million square kilometers (compared to the current six million). Informed choice for ice-free summer was considered to be approximately 2,100 years, but now scientists have analyzed the dynamics of sea ice in the modern, interconnected models for the period up to 2100, based on different scenarios of anthropogenic emissions of carbon dioxide, and relegate this period of 50 years closer. The results of a study published in the journal Geophysical Research Letters.
For the past 700 thousand years, a large area of Arctic ocean covered by ice, which melts during the summer season and reaches a minimum at the beginning of September, but never disappears completely. In recent decades, the amount of sea ice in the Arctic has slowed down significantly in our country, for example, melting glaciers in the Arctic circle has increased by half. Further reduction of ice is a threat to the environment (in particular, for populations of polar bears), while the dynamics of sea ice is very difficult to predict — it has considerable variability
