What is the impact of sea level rise or 2 meters on human beings

It is estimated that the sea level will rise by 2 meters by 2100. What impact will it have on human beings? Runaway carbon emissions and melting ice sheets could cause sea level to rise by 2 meters in 2100, with a probability of 5%, British scientists said in a new research report, New Scientist website reported on the 20th. Once this happens, it will have a 'profound impact' on human beings.

Jonathan & middot; Bamber of the University of Bristol said: 'if we see this in the next 80 years, it will lead to an unimaginable social collapse. '

Banber further said that at that time, about 1.79 million square kilometers of land may be submerged by the sea, and as many as 187 million people will be displaced. "Many small island countries, especially those in the Pacific Ocean (3.350, - 0.08, - 2.33%), will become very uninhabitable. '

The team came to this conclusion after obtaining evidence from 22 senior researchers on how the Greenland and Antarctic ice sheets respond to future climate change. They said that if the global average temperature rises by 5 ℃ due to uncontrolled carbon emissions, the probability of sea level rising by more than 2 meters in 2100 will reach 5%.

In 2013, the United Nations Intergovernmental Panel on climate change (IPCC) issued a report that the worst case of sea level rise is to rise 98 cm by 2100; if Antarctica begins to collapse in this century, then add a few tenths of meters on this basis. Banber said the IPCC did not consider the possibility of reasonable but low probability, so it ignored the serious impact that might occur.

What changes have taken place since 2013 that will lead to sea level rise so much in the future? One factor is that satellite measurements in recent years have shown that the loss of ice mass is happening faster than expected; another key problem is that the ice cliffs in Antarctica may collapse under their own weight after their supporting ice sheet melts due to climate change, the researchers explained.

Banber also pointed out that if emissions fall fast enough, then we can still avoid the catastrophic risk of a two meter rise in sea level.
