Scientists report on record ice melting in the Arctic

The level of Arctic sea ice over the past two years has achieved a new record minimum. This is reported in the annual report of the international program Copernicus Ocean. It had been prepared by 120 scientists from more than 30 European institutes and published in the Journal of Operational Oceanography.
 
The report notes that over the past decade, the level of Arctic ice has decreased by 13 percent compared to 1979, and the average ice thickness in the Barents Sea has decreased by 90 percent.
 
The experts estimate that warming of the Arctic Ocean now accounts for about four percent of all global ocean warming. A sharp reduction in ice flow from the Arctic to other basins, according to scientists, may accelerate this process, which already result in extreme flooding and changes in the species composition of of marine flora and fauna.
 
As examples, the report authors cite record flooding in Venice in November 2019 and four episodes of rising water in the middle and southern Mediterranean that year. In the North Sea, extreme variability associated with alternating periods of cooling with seas of warmth has led to declines in many commercial species, such as flounder, European lobster, sea bass, mullet and edible crabs.
 
"Climate change, pollution and overexploitation of marine resources are putting unprecedented pressure on the ocean. It requires an urgent need for sustainable management and adaptation measures," Karina von Schuckmann of Mercator Ocean International Corporation, which coordinated the study, said in a press release from the publisher. - Considering the ocean as a fundamental factor in the Earth system and understanding the multi-dimensional and interconnected nature of the ocean  is the basis of a sustainable future."
