Scientists have looked back in time to reconstruct the past life of Antarctica’s “Doomsday Glacier” — nicknamed because its collapse could cause catastrophic sea level rise. They have discovered it started retreating rapidly in the 1940s, according to a new study that provides an alarming insight into future melting.
The Thwaites Glacier in West Antarctica is the world’s widest and roughly the size of Florida. Scientists knew it had been losing ice at an accelerating rate since the 1970s, but because satellite data only goes back a few decades, they didn’t know exactly when significant melting began.
Now there is an answer to this question, according to a study published Monday in the journal Proceedings of the National Academy of Sciences.
By analyzing marine sediment cores extracted from beneath the ocean floor, researchers found the glacier began to significantly retreat in the 1940s, likely kicked off by a very strong El Niño event — a natural climate fluctuation which tends to have a warming impact.
Since then, the glacier has been unable to recover, which may reflect the increasing impact of human-caused global warming, according to the report.
What happens to Thwaites will have global reverberations. The glacier already contributes 4% of sea level rise as it sheds billions of tons of ice a year into the ocean. Its complete collapse could raise sea levels by more than 2 feet.

It’s melting because it’s getting warmer.
In fact, it’s been getting warmer for about 15,000 years and will continue to do so for about 18,000 more.
Then it will begin to get colder.
We had nothing to do with it and there’s nothing we can do about it.
“Could.”
Which means with the best technology currently on the planet, the best they can do is “could.”
Yes, but, I think the general claim is that these glaciers sit on a landmass.
It’s a pure BS climate cultist alarmist made up story.

Do they mean like this cold??
What caused all this to melt?
I bring this up a work and boy, oh boy, does it upset the applecart.
Let me know when the doom finally arrives.
I’ve been waiting my entire life. First there was this population bomb, then a hole in the ozone, then a new ice age, then a nuclear holocaust, then meteors crashing into earth, then global warming, now “climate change”. Get it over with, already! The suspense alone should be killing me, but it isn’t!
It’s sliding off the Continental shelf and into the sea. The floating part of Thwaites was extends about 30 miles over the sea. The part still on land mass is larger than the floating part. The floating part somewhat stabilizes the landbound part and the concern is that as the floating part melts (which it is), the land part will progress into the sea more rapidly.
Only one thing. I do like just one good snowstorm. Right before Christmas. That’s it. Gone by New Year. Spring starts Jan.2nd. I’m not askin’ for much, am I?
It’s the part in the sea that breaks off.
No change.
