Only two abnormally warm months of summer caused a rise in the level of the World Ocean by 2.2 millimeters.
Scientists have recorded a significant melting of the glaciers of Greenland, which caused the rise in sea level. This was reported in the journal Geophysical Research Letters.
Satellite imagery showed that in just two summer months they had caused a loss of 600 billion tons of ice. Because of this, the level of the oceans rose by 2.2 millimeters.
According to the GRACE satellite mission, the summer of 2019 was the hottest in the Arctic region in the entire history of observations. It turned out that the freshwater that the glaciers lost in just two summer months would be enough for a 10 million-strong metropolis for 600 years.
It is noted that the intensity of glacier melting over the summer of 2019 turned out to be seven times higher than it was in the 1990s. Such indicators will lead to the fact that by the end of the twenty-first century, 400 million people will be at risk of flooding every year.
Intense glacier mass losses are also observed in Antarctica, but in the east of the continent, there is still a compensated accumulation of ice.
Earlier it was reported that glaciers melt six times faster than 30 years ago. The Correspondent also wrote that a new island appeared in Antarctica.
