Rolling Stone's New Years Eve Missive
I never expected Rolling Stone magazine to close out 2021 with an "end is nigh" message but these are curious times.
The headline couldn't be more dramatic: "The Fuse is Blown, and the Doomsday Glacier is Coming For Us All."
A few weeks ago, scientists participating in the International Thwaites Glacier Collaboration, a $25 million five-year-long joint research program between the National Science Foundation in the U.S. and the Natural Environment Research Council in the U.K., presented their latest research. They described the discovery of cracks and fissures in the Thwaites eastern ice shelf, predicting that the ice shelf could fracture like a shattered car window in as little as five years.It's not the ice shelf that poses the threat. It's the Thwaites glacier behind it that would eventually slide into the ocean, taking with it the rest of the West Antarctic glaciers resulting in sea level rise upwards of six to ten feet.
The big question now isn't if but when. The rest of the Thwaites ice sheet could dislodge within just five years. The IPCC predicts sea level rise of barely one foot to six feet by the entirely arbitrary date of 2100. The West Antarctic glaciers could render the IPCC projections meaningless.
Or to put it more urgently: “If there is going to be a climate catastrophe,” Ohio State glaciologist Ian Howat once told me, “it’s probably going to start at Thwaites.”
Five years, three years, ten years, does it really matter?
The trouble with Thwaites, which is one of the largest glaciers on the planet, is that it’s also what scientists call “a threshold system.” That means instead of melting slowly like an ice cube on a summer day, it is more like a house of cards: It’s stable until it is pushed too far, then it collapses.
We don't know how it's going to happen. We don't know when it's going to happen or how fast. All we know is that it will happen. We know it could happen quickly or more slowly. Many of you may see this unfold in your lifetime. I hope it doesn't happen in mine.
