Climate models are likely overestimating how much Antarctic ice sheets could contribute to sea level rise. Ice sheet simulations, a recent study showed, don’t fully account for the way supporting bedrock rebounds upward when ice above shrinks. This effect could slow melting by up to 20%.

Rising ground in the Antarctic lifts melting ice sheets, limiting sea level rise
Models might not be taking into account an important phenomenon that helps to mitigate ice sheet melt and, as a result, sea level rise. Image credit: Shutterstock/Goldilock Project
