Scientists have reported record ice melting in the Arctic. This is stated in a report prepared by 120 experts from more than 30 European institutions.
Over the past decade, Arctic ice levels have decreased by 13%, and the average ice thickness in the Barents Sea has decreased by 90%, according to the report.
The Arctic Ocean is warming and this process accounts for 4% of all global warming. If the amount of ice from the Arctic entering other basins decreases, it will further accelerate warming, scientists say.
Climate change, pollution and overexploitation of marine resources are putting unprecedented pressures on the ocean, demanding an urgent need for sustainable management and adaptation measures. Viewing the ocean as a fundamental factor in the Earth system and understanding the multidimensional and interconnected nature of the ocean is the foundation of a sustainable future.

The authors also noted the strong impact of climate change on the ocean. Between 1993 and 2019, global average sea temperatures rose at a rate of 0.015 ° C per year.
In addition, for example, in the Black Sea from 1955 to 2019, the oxygen content in the waters decreased annually at a rate of 0.16 mol / m2 / year.
As a result, the authors of the report emphasize the need to improve ocean monitoring tools to better predict its rapid changes.
