According to a recent study on the world’s oceans and climate change, the ice level in the Arctic has hit historic lows.
Between 1979 and 2020, the average sea ice extent in the Arctic, defined as the region of the sea with at least some ice, decreased by an area almost the same as that of Greenland.
The results were published last week in the Journal of Operational Oceanography in the fifth edition of the Copernicus Ocean State Report.
More than 120 scientific specialists from more than 30 European universities participated in this year’s study.
The annual publication gives a detailed overview of the state of the world’s oceans.
The study discusses some significant changes and trends in the world’s oceans.
For example, from January 1993 to May 2020, sea levels rose by an average of 3.1 mm per year.
The Baltic Sea was hardest hit, increasing at a rate of 4.5 mm per year.
During the same period, sea temperatures rose by an average of 0.015 degrees Celsius every year.
At the top of the list was the Black Sea with an annual temperature increase of 0.071 degrees Celsius.
It is believed that the warming of the Arctic Ocean is responsible for about 4% of global ocean warming.
In November 2019, there were four consecutive record floods in Venice, Italy, as well as above-average wave heights in the southern Mediterranean, according to the study.
