There are a lot of daunting aspects of climate change, but few are more frightening than what’s happening right now at the bottom of the world. A few large glaciers in Antarctica have already passed over into slow-motion collapse mode. If these “doomsday glaciers” crumble, they would drown every coastal city in the world. A little over a year ago, I wrote about this “Ice Apocalypse” scenario and the scientists who are working diligently to understand how much time we have before this turns into a full-blown catastrophe.
That research got an update last month, which could be perceived as good news: If we steer our emissions away from business as usual, we might be able to reduce the chances of outright collapse during this century to about 10 percent. The worst-case scenario is still on the table and the details are still fuzzy, but this is about as close as it comes to a sigh of relief when you’re talking about trillions of tons of ice hanging by a thread and holding all of coastal human society hostage.
