Loss of glacier would imperil coastlines worldwide

This is the natural fate of all glacier ice. The problem comes when more ice is lost to the ocean than is replenished from snowfall, which is now happening at Thwaites on an epic scale.

Since 2000, the glacier has lost more than a trillion tonnes of ice, and this rate of loss has doubled in the past 30 years. The big worry is that, if it collapsed entirely, it could ultimately trigger a wider collapse of the ice of the entire West Antarctic ice sheet, causing a calamitous sea-level rise of more than 3 metres, on average, changing the coastline of the entire planet.

“We see it slowly collapsing before our eyes,” says Mathieu Morlighem at Dartmouth College in New Hampshire. The front of the glacier, where the ice flowing from the continent meets the sea, is rapidly retreating inland.

Thwaites glacier is the “wild card” in the climate models, say Ted Scambos at the University of Colorado, Boulder. “It has the potential to dramatically change what sea-level rise will look like.”

1. The ugly truth is

There are many in Red America, and some in Blue America, that would LOVE to see Eastern cities destoryed. A0 because they could make money and B) because they resent the nation that those cities serve.

Yeah Bubba, we can drown all the immigrants
Yeah Bubba, we can drown all those eastern universities that make us kids arrogant and lazy
Yeah Bubba, we can for NY ork money to go to the midwest, and then force that money to go to Texas and Alabama

You know they are saying that, and the Bill Maher/Rahm Emanuel faction of the so called "left" is ready to cheerlead.

2. Wait until they find out that the shoreline of the US coast that abuts the Gulf of MEXICO

is predicted to be among the worst hit by climate change, and that the rate of the rise in sea level is already higher than most of the rest of the USA. A few keys facts (from AI, take from this as you will):

Low elevation and subsiding land
More than 7,000 square miles of the U.S. Gulf Coast lie below 5 feet in elevation, including major urban centers and infrastructure nodes like Houston and New Orleans.

Large stretches of the Gulf Coast are subsiding due to groundwater, oil, and gas extraction, plus wetland loss—so relative sea‑level rise (water up + land down) can be equal to or greater than the global average.

This combination of low elevation and subsidence makes the region extremely sensitive to both chronic “nuisance” flooding and catastrophic storm‑surge inundation as sea level rises

4. Since AI providers tell us to check their results,

we might as well do the work ourselves and not waste the gigWatts.

Projected properties at substantial flood risk in 2050: 809,800 (35.8%)

3. Not a question of if, but when ... thanks industrialized nations

Since the best that modern scientists can hope for is merely a reduction in the rate of increase of global warming temperatures, the eventuality of what you portend above will happen, likely within the next fifty years. Global warming will continue and glaciers will continue to melt as per entropy demands until continents shrink away.
Wildfires will continue to be more and worse.
Heat waves will continue to be hotter and longer and get worse.
Fossil fuel usage and renewable energy suppression under trumpass administration will help accelerate the rate of increase even more.
Americans answer to the problem is 'turn up the air conditioner it's hot in here', which in itself will add to global warming by more energy use.
The upward spiraling in global warming is uncontrollably out of control.
In retrospect, thanks industrialized nations, for nothing.

5. 2/3 of Pakistan flooded a few years ago

It was disastrous. They openly blamed the West for climate change. And they have nukes.

7. Add data centers with

massive electrical and water demands.

The earth will survive, humans won't.

8. Reminds me of the Hemingway quote:

“How did you go bankrupt?"
Two ways. Gradually, then suddenly.”
