West Antarctic glacial collapse: What you need to know
Q: Why is the collapse of an ice sheet so important?
A: The science of global warming comes down to ice. Though Earth’s warming, the planet is currently in an ice age, and great sheets of ice at the poles — think Greenland and Antarctica — have not always existed. In the past, sea levels were actually significantly higher than they are in this era’s environment, which allowed contemporary civilization to thrive.
If all of the ice was to melt at the poles, the National Academy of Sciences predicts the sea level rise approximately 60 meters — about 200 feet. That would result in “storm surges more likely to cause severe impacts” and “coastal inundation.”
Q: How did researchers come to this conclusion?
A: Both teams of scientists came to a strikingly similar conclusions about West Antarctic’s glacial collapse — but through very different means. The NASA study used satellite radar to scrutinize several glaciers hugging the Amundsen Sea that contain enough water to raise sea levels by four feet. They found a “continuous and rapid retreat,” and that there is “no [major] obstacle that would prevent the glaciers from further retreat.”
The University of Washington researchers used computer simulations to come to the same conclusion, but with an added caveat: One of the glaciers, Thwaites, acts as a “linchpin” on the rest of the ice sheet — which contains an additional 13 feet of global sea rise. “In our model simulations it looks like all the feedbacks tend to point toward it actually accelerating over time,” explained lead author Ian Joughlin. “There’s no real stabilizing mechanism we can see.”
Q: What’s the endgame?
A: A very different planet. Some scientists say the collapse of West Antarctica is only the beginning. Regardless of Monday’s findings we may have already triggered nearly 70 feet of additional sea rise.
