The ice gradually disappears from June to September.
Scientists at the University of Cincinnati (USA) came to the conclusion that Arctic sea ice can completely stop their formation in September of each year, if the global average temperatures will rise at least two degrees. This will lead to catastrophic changes in polar ecosystems.

The simulation results showed that there is a 6% probability of the disappearance of summer sea ice with warming at 1.5 degrees Celsius above pre-industrial levels. When the temperature increases by two degrees, the probability increases to 28 percent.
September, which is the transitional period between summer and winter, is characterized by the smallest area of ice cover in the Arctic ocean. The ice gradually disappears from June to September, and autumn to the area once again begins to increase. However, the disappearance of the ice cover in September, decelerates the return of the Arctic to winter mode, which is a threat to seals and polar bears.
According to the Paris agreement of 2015, the global average temperature increases must be limited to the value of 1.5 degrees Celsius to avoid catastrophic climate change scenarios. It was reported that an international group of scientists from Austria, France, great Britain, Germany and Switzerland came to the conclusion that the melting of permafrost and associated carbon emissions will inevitably lead to exceeding the permissible temperature rise.
