Latest research: Greenland melting will increase the sea level of at least 27 cm

[Global Times Comprehensive Report] Climate warming continues to threaten global ecology and human survival space. The Associated Press reported on the 30th that a latest study shows that the melting of the "zombie ice" from Greenland is the ice crown will increase the sea level of at least 27 cm, which eventually leads to the disappearance of Bangladesh, New York, Miami and other countries and regions Essence

Researchers said that the so -called "zombie ice" refers to although it is still connected to the Greenland ice cover, but it can no longer get glaciers or new snowfall supplements, and can only slowly melt the ice layer of "waiting for death". What is even more worrying is that no matter what the climate change process, the temperature of the Arctic region will rise, and the melting of the local "zombie ice" cannot be avoided. The researchers said that because the "zombie ice" could not be supplemented by glaciers or snowfall, it was as if there was no food to eat, and they would eventually "starve to death." In addition, the rise of the sea level by 27 cm is a global average. In fact, there will be differences in different regions. For example, the level of sea levels far from Greenland will be higher. It will be lower.

Researchers predict that even if the international community takes measures such as carbon reduction to cope with climate change, Greenland's ice layer will melt at least 3.3%. A scientist said that 1.1 million tons of ice on Greenland will melt. If all these ice -mellast water are concentrated in the United States, it will cause the United States to be submerged under 11 meters deep. It is worth mentioning that this is the world's first research on the minimum melting amount of Greenland's ice layer and the rising correlation of the sea level, but the research results are not optimistic.

The melting of Greenland ice layer will cause the sea level to rise, and there is no conclusion at this time. Last year, the Special Committee for Climate Change of the United Nations (IPCC) issued a report that the melting of Greenland's ice layer may cause sea levels to rise by 6-13 cm before 2100. This estimation result is only equivalent to less than half of the latest research. However, another study has previously reached a more pessimistic conclusion that the melting of the Greenland ice layer may cause the sea level to rise by 78 cm.

In addition, the melting timeline of Greenland is not sure. A expert says that although the above -mentioned research is in line with the more complicated ice -melting model, the "zombie ice" may not be basically melted in the 21st century.
