Antarctica’s Post-Glacial Uplift: A Double-Edged Sword for Future Sea Level Rise
Antarctica, long regarded as a frozen behemoth, is shedding its icy weight, leading to a phenomenon known as post-glacial uplift. This process, where the land rises as the ice melts, is now recognized as a key factor that could dramatically alter projections of future global sea level rise.
As the Antarctic ice sheet melts, the weight pressing down on the continent reduces, allowing the land to rise—similar to a sponge expanding after being compressed. This process, called post-glacial uplift, is happening much faster than previously thought. Recent research suggests that this land rebound could either mitigate or exacerbate Antarctica’s contribution to global sea level rise, depending on future fossil fuel emissions.
