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.
But it also plays a vital role in the stability of the West Antarctic Ice Sheet, acting like a cork holding back the vast stretch of ice behind it. Thwaites’ collapse would undermine the stability of the ice sheet, which holds enough water to raise sea levels by at least 10 feet, causing catastrophic global flooding.

It’ll make a LOT of difference to those who are reaping the cash benefits of this sham.
That’s NOT you or me, in case I wasn’t clear. ;)
That, my FRiend, is a given!
Yeah, when the Obama’s sell their Martha’s Vinyard estate, and Jill Biden’s her husband’s Delaware beach house, and Baba Streisand her Malibu home, then I’ll worry...
“One sits on a bend in the road. The road was put in early 1800s. They just went around it. It is about 15’ high and 20’ long.”
I bet there’s a coyote under it.
Darn I wanted that to be true!
But it sounds like the rock has been moved more than once.
Absolutely.
It’s not what the evidence shows, but how one interprets it. CO2 going up is actually good for plant life, and thus all life that relies on it.
Humanity’s annual output of 29 gigatons of CO₂ is small compared to the 750 gigatons naturally moving through the carbon cycle each year.
Just one large volcano eruption in any single year can easily equal or exceed all of humanity’s annual output.
Finally proof that SUVs cause global warming. The first Chevy Suburban rolled off the line in 1935. Five years later the Pine Island Glacier begins to melt.

They have actually traced the beginning of the doomsday down to the very day it started, June 14, 1946, the day Donald Trump was born.
Plymouth Rock was moved but I’m not sure if it was done to keep it above water or more likely to safekeep it from development in the area. You see lots of old photos of headlands and lighthouses that look just the same today.
91 active volcanoes under the ice sheet! Volcanic activity hot ice sheet cold ice melts!
"What IS the optimum temperature for mankind on earth?"
Yup. No one can answer, as there isn’t an answer.
Also, try this mental exercise:
Imagine you are an alien explorer from a far distant galaxy. However, you can only visit the Earth every 50 million years or so. How many times could you have visited in the entire history of planet Earth?
80.
4 Billion divided by 50 million = 80.
That’s a lot of visits!
Now imagine your last visit. 50 millions years ago the Earth was in the Cenozoic Era in the Eocene Epoch. There was no ice caps, anywhere. The Earth was warm, with palm trees, lemurs and crocodiles well North of the Arctic and South of the Antarctic circles.
you’d pop in and the first question would be:
Who turned off the heat? What’s this white stull at the top and bottom?
In previous visits many times ago, you would have witnesses snowball Earth but a only a couple of times—a cold Earth is a rare Earth.
It is what it is, no? Mankind is after all, a product of the Earth, and any affect mankind has on the Earth is, well, part of the Earth!
Bottom line is ocean levels rise and fall over time
Temps warm and cool.
The climate cultist want to tie every change to Americans driving a SUV which is junk science .
That is a way of looking at it that I have never considered! Very effective.
This could actually happen but it isn’t caused by human anything.
The Driftless Area is cool. Been there. Cave of the Mounds and the House on the Rock. Great attractions.
The river near us, the Rock River, is kinda low…it would be great if some of that glacier water made it here. I know it won’t, but maybe storms later on tonight might raise it a little.
My wife calls this weather lately “bipolar”. I think she’s right.
Gorgeous indeed....which surprised me as I schooled at NIU in Dekalb where its flat as my table top....out west near the Mississippi / Galena the beauty begins.
You must be just north of that.
Gotta’ say that’s pretty damn nice.
I feel sorry for the penguins
