According to “New Scientist”, British scientists pointed out in the latest research report that runaway carbon emissions and melting ice caps may cause sea level rise by 2 meters in 2100, with a probability of 5%. Once this happens, it will have a “profound impact” on humanity.

Sea level rise may 2 meters by 2100

Jonathan Bamber of the University of Bristol said: “If we see this happening in the next 80 years, it will lead to unimaginable social collapse.”

Bamber further said that by then, approximately 1.79 million square kilometers of land may be submerged by sea water, and as many as 187 million people will be displaced. “Many small island countries, especially those in the Pacific, will become very uninhabitable.”

Bamber’s team reached this conclusion after gathering evidence from 22 senior researchers about how the Greenland and Antarctic ice sheets will respond to future climate change. They said that if carbon emissions are not controlled and the global average temperature rises by 5°C, the possibility of sea level rise by more than 2 meters in 2100 will reach 5%.

In 2013, the United Nations Intergovernmental Panel on Climate Change (IPCC) released a report stating that the worst-case scenario for sea level rise is 98 centimeters by 2100; if Antarctica begins to collapse this century, this area will increase again. Bamber said the IPCC failed to consider reasonable but low-probability possibilities and therefore ignored potentially serious impacts.

What has changed since 2013 that will cause sea levels to rise so much in the future? One factor, the researchers explain, is that satellite measurements in recent years have shown that ice mass loss is occurring faster than expected. Another key issue is that Antarctica’s ice cliffs may lose weight after their supporting ice sheets melt due to climate change. Will collapse under its own weight.

Bamber also pointed out that if emissions fall quickly enough, we can still avoid the catastrophic risk of 2 meters of sea level rise.
