The West Antarctic Ice Sheet is vulnerable to catastrophic collapse—a scenario that could raise global sea levels by 3 meters in the coming centuries—because it sits on bedrock that lies far below sea level. A new study published by Science documents a process that could slow the collapse. As ice melts and the crust is lightened, the bedrock beneath West Antarctica is rising rapidly. In places it could rise 8 meters over the coming century, potentially protecting the ice from the warm seawater that is melting it from below.

上升的基岩可能会延迟冰盖崩塌

南极西部冰盖很容易发生灾难性崩塌——这种情况可能在未来几个世纪将全球海平面升高 3 米——因为它位于远低于海平面的基岩上。《科学》杂志发表的一项新研究记录了一个可以减缓崩溃的过程。随着冰融化和地壳变轻，西南极洲下方的基岩正在迅速上升。在未来的一个世纪里，在某些地方，它可能会上升 8 米，从而有可能保护冰免受从下方融化的温暖海水的影响。
