On our first morning at the Thwaites Glacier in West Antarctica, the air was still. The captain made a brave choice: Our ship would hold close to the ice shelf so that the sonar system would peer beneath it while producing a detailed map of the seafloor. The scientists on board, along with the writers like me, were the first people in the history to visit this part of Thwaites. Our task was to bring back as much information as possible about the place where ocean and ice meet.
If Antarctica collapsed, it could threaten the entire West Antarctic Ice Sheet, causing global sea levels to jump 10 feet or more. In terms of the fate of our coastal communities, this particular glacier is the biggest wild card, the largest known unknown. Will Miami even exist 100 years? Thwaites will decide.
Reading about the collapse of Antarctica’s glaciers, I feel I am being encouraged to jump to a conclusion: that no matter what we do now, what lies ahead is bound to be worse than what came before. This kind of thinking turns Antarctica into a passive symbol of the coming disaster. But what if we were to see Antarctica as a harbinger of change rather than doom(厄运)? This is why I came to Thwaiters. I wanted to find out: Antarctica has the power to rewrite all our maps.
This week a paper analyzed the data from that exploration. The authors suggested that sometime Thwaites retreated at two to three times the rate we see today. Put another way: At the coldest period of the planet, Thwaiters is stepping farther outside the script we imagined for it, likely challenging even our most detailed predictions of what is to come.
It took us nearly a month to arrive at the edge of Thwaiters. It is one of the most remote region on Earth. But despite the distance, what happens there is shaping us just as much as we are shaping it. If we can begin to recognize the agency of this faraway glacier, we will be one step closer to embracing the modesty that climate change demands.
