Over the past ten years, the level of Arctic ice has decreased by 13%. This is a record

Over the past decade, Arctic ice levels have shrunk by 13% and average ice thickness, according to the report.

in the Barents Sea decreased by 90%.

The Arctic Ocean is warming and thisthe 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 excessiveThe exploitation of marine resources is placing unprecedented pressure on the ocean, requiring urgent and 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.
