As Greenland loses ice, global sea levels will rise—and its own will fall: The island is rebounding from ice melt so fast that scientists are rethinking how Earth's interior works.

The article discusses a new study revealing that Greenland's ice sheet melting is causing the land beneath it to rebound rapidly, leading to a paradoxical situation where sea levels may fall in certain areas of the island even as they rise globally. This phenomenon, known as glacial isostatic adjustment, is occurring faster than previously anticipated, with projections indicating that parts of Greenland's coast could see sea levels drop by 1 to nearly 4 meters by 2100. The study highlights potential challenges for navigation and local ecosystems, as well as the importance of future carbon dioxide emissions in determining the extent of these changes. The findings suggest that while some areas will experience rising sea levels, others will face unique complications due to land rebounding from ice loss. [Extracted from the article]
