According tomedia reports, the melting of ice and snow in the Antarctic Circle caused sea level rise will be evident in this century, and more than previous estimates. A team of international scientists suggests that melting Antarctic ice alone could cause sea levels to rise by 58 cm by 2100.
A team led by Anders Levermann of the Potsdam Climate Institute in Germany concluded that sea levels would rise between 6cm and 58cm without a drop in greenhouse gas emissions, and that if greenhouse gas emissions dropped significantly, sea levels would rise by between 4cm and 37cm.
“There is still a lot of understanding of the Antarctic factor, which is why it is a huge risk of sea level rise, ” says Mr Rifman. He stressed that the latest research was first and foremost to provide vital information to protect coastal areas, saying that sea level rise of more than 58 cm is unlikely.
Research also shows that, in the long run, melting Antarctic ice could even raise sea levels by tens of meters in the next century and next millennium. “What we can be sure of is that burning coal, crude oil and natural gas will increase the risk in coastal metropolises such as New York and Mumbai,” Mr. Reifman said. “
So far, sea-level rise projections have been based on global warming, especially as rising sea temperatures and melting glaciers are the most important factors. Greenland’s melting ice also plays an important role here.
The results, published in the Journal of Earth System Dynamics, published by the European Union of Geosciences, suggest that Antarctica is likely to become the most central factor in sea level rise in the near future.
All of these factors combine to pose an overall risk of sea level rise, and Mr Reifman said that by the end of the century, excluding The Antarctic, “Greenland’s rising temperatures, melting glaciers and ocean enlargement could lead to sea level rise of 150 cm”. In the past 100 years, sea levels have risen by only 19 cm.
Carlos Schaefer, a Brazilian geological scientist, measures the temperature of the Antarctic surface. On February 9 this year, his team measured a temperature of 20.75 degrees at the northern tip of Antarctica. Temperatures in Antarctica have never been higher, he said, and this is the first time it has exceeded 20 degrees Celsius. But he also stressed that record-breaking temperatures alone could not lead to future climate change.
A week ago, Argentina’s meteorological adgies also measured the highest temperature record: 18.3 degrees Celsius at a research station in Argentina’s Antarctic region.
