Sea level in the world may rise 7m

Professor Garry Clarke of the University of British Columbia (Canada) warned that sea levels around the world could rise by 7m if the entire ice sheet on Greenland Island in the North Sea melted.

The ice sheets in Greenland, the world's largest frozen area, are currently melting very rapidly in areas exposed to seawater, while the ice in the highlands at the center of the island is not yet affected. However, if the global warming situation makes sea level rise, the thawing of Greenland will be worse than the melting periods that occurred hundreds of thousands of years ago.

Professor Garry Clarke said that perhaps the entire ice cover of Greenland will disappear, though it is not known how fast this will happen.

Scientists believe that there are still many issues to learn about the Arctic ice because the current research models on the region have become obsolete. Even so, the results of these studies can help predict the flood situation in low-lying countries.
