Antarctic glaciers melting due to global warming could push sea levels faster than previously believed. The German researchers say, it is potentially threatening major cities, such as New York and Shanghai, sank.
In this century, the Antarctic ice discharge could raise sea levels by 37 centimeters (14.6 inches), especially if the effects of greenhouse gases continues to grow. Thus the results of a study led by the Potsdam Institute for Climate Impact Research in Germany. According to the researchers, the increase may at least 1 centimeter.
"This is huge, that's why we call it a risk," said Anders Levermann, lead author of the study.
"Science should be able to explain this uncertainty so that the decision makers at the beach and coastal big cities may consider the implications in the planning process they face a variety of possibilities," he added.
NASA estimates, the glaciers in the Amundsen Sea region contains enough water to raise global sea levels as high as 4 feet (1.2 meters) and the melting of glaciers may not be the "unstoppable".
"Previous research has shown that the Antarctic will be important in the long term," said Levermann. "But, all the evidence seems to point that Antarctica could become the dominant cause of rising sea levels faster," he said
