WebIntroduction This simulation explores the impact of collapsing polar ice sheets (Greenland and Antarctica) and their impact on global mean sea level rise, along with shrinkage in livable area around the world. Here, we look at US coastal areas, and how shoreline would retreat if Greenland and Antarctica were to dramatically decrease in volume. Web22 okt. 2024 · Global sea level has been rising at a rate of 0.1 inches (3.3 millimeters) per year in the past three decades. The causes are mostly the thermal expansion of warming ocean water and the addition of fresh water from melting ice sheets and glaciers.But even as the sea takes up more space, the elevation of the land is also changing relative to the sea. fisiosesto
