受全球变暖等因素影响，格陵兰岛正在缩小且向西北漂移

Core Insights - A recent study indicates that Greenland is shrinking in size and drifting slowly northwest due to global warming and other factors [1][3] Group 1: Research Findings - The study, conducted by researchers from the Technical University of Denmark and published in the journal "Geophysical Research Letters," analyzed data from 58 global navigation satellite system monitoring stations around Greenland [3] - Greenland is drifting northwest at a rate of approximately 2 centimeters per year, with some areas experiencing uplift while others are sinking [3] - The horizontal crustal movement in Greenland is influenced by three geological forces: tectonic plate interactions, reduced pressure on the bedrock due to glacial melting, and long-term rebound from the last ice age [3] Group 2: Climate Impact - The movement of Greenland highlights how climate change-induced glacial melting is reshaping the surface and affecting geological foundations [3] - Greenland's ice sheet is one of the world's largest freshwater resources, with enough water to potentially raise global sea levels by 7.4 meters [3] - According to the Copernicus Climate Change Service, a 1-centimeter rise in sea level puts approximately 6 million people at risk of coastal flooding globally [3]
