cientists are warning an Antarctic glacier could collapse and cause sea levels to raise at least a foot in the next decade.
The scientists said Monday at the American Geophysical Union the Thwaites glacier, which is the size of Florida, could collapse in the next three to five years.
The ice shelf holding the glacier in place is quickly developing cracks due to the warm water hitting it, according to the scientists.
"There's going to be a dramatic change in the front of the glacier probably within less than a decade," Ted Scambos, a senior research scientist at the Cooperative Institute for Research in Environmental Sciences, said.
"It's doubled its outflow speed within the last 30 years, and the glacier in its entirety holds enough water to raise sea level by over 2 feet. And it could lead to even more sea-level rise, up to 10 feet, if it draws the surrounding glaciers with it," he added.
He said the collapse of the glacier could harm glaciers nearby due to its size and cause them to fall as well.
The warning from scientists comes after a hole two-thirds the size of Manhattan was found in Thwaites glacier.
"Researchers expected to find some gaps between ice and bedrock at Thwaites' bottom where ocean water could flow in and melt the glacier from below," NASA said at the time. "The size and explosive growth rate of the newfound hole, however, surprised them."

But suppose the whole was larger 100 years ago?? And is actually smaller now.

We’re all gonna die?
Could the increased penguin population cause the entire continent to capsize?
Thanks for this. I would love to see their mathematics for how the global oceans will rise by ‘at least a foot’. As you noted, that would take a serious number of cubic miles of water. Even then, as the oceans grow in height, more surface is exposed meaning even more volume is required to keep it rising. It’s not linear.
Let me think about that.... Ice is floating - then it melts and joins the rest of the Ocean. When water freezes to become ice the volume expands somewhat. So when ice melts it will take up less volume. The Ocean level will drop. Oh - my now what will we do????
Bull dog has non concern.
Yes, we are nearing the peak of an inter-glacial phase …
We wouldn’t need ANY new superglue if politicians would just stop sniffing what they have now.
I don’t think this is a huge deal either, but you are missing a key point. The ice is not currently sitting in the ocean. It’s about to fall into the ocean. That will displace some volume. For a while.
Something that big is going to cool some water. And that cold water is going to circulate, cooling down other stuff.
That’s how the earth seems to work. We are not going to change that.
Have these polyannas ever been right about one single thing? Didn’t think so.
“Cooperative Institute for Research in Environmental Sciences, said.”
Yeah, that’s a real place where real science is done.
