One of the ever-looming threats of climate change is sea level rise, which already threatens to displace millions of people worldwide and force them to move inland by the end of the century. A big part of the rising water levels are hotter temperatures at the poles—home to giant glaciers and ice shelves that hold crucial quantities of frozen H2O.
The Florida-sized Thwaites glacier in Antarctica, nicknamed the “doomsday glacier,” is already losing 50 billion tons of ice each year. That in itself accounts for around 4 percent of annual global sea level rise. But unpublished research shared at the American Geophysical Union fall meeting this week shows that the thinning ice shelf extending from Thwaites could shatter within the next three to five years. Behind Thwaites lies an even larger body of ice that, if the glacier melts, will be exposed to increasingly warm waters.
“Thwaites is the widest glacier in the world,” Ted Scambos, a senior research scientist at the Cooperative Institute for Research in Environmental Sciences (CIRES) and lead coordinator for the International Thwaites Glacier Collaboration (ITGC), said in a press release. “It’s doubled its outflow speed within the last 30 years, and the glacier in its entirety holds enough water to raise [global] sea levels by over two feet. And it could lead to even more sea level rise, up to 10 feet, if it draws the surrounding glaciers with it.”

I thought Antarctica was in a deep freeze about three years ago.
Remember the many pictures of sad polar bears on jagged ice floes?
..............................................
Hey Frank, no one has to remember those pictures because the World Wildlife Foundation ran the polar bear clips in its fundraising commercial LAST NIGHT! Momma bear with cubs stranded on an ice flow, yada yada yada! Send us some money!
I am not worried in the slightest.
Wow.
I always think I’m ready for the next preposterous BS coming my way but I am not.
Incredible.
Thanks for the heads up.
Awww. Why let facts get in the way of such great Doomsday porn?
Sell the fear. When Miami, Nawlins, the Obama mansion and the Bahamas disappear, we’ll know something.
Woman panicking picture....
Finally someone taking this crisis seriously.
Maybe the space aliens can use red hot beams to evaporate the rising sea level water before it hits the coasts. Then they’ll say the extra steam droplets are exacerbating the Omicron wave.
Can’t win.
Its melting dueto heat. Doesn’t any of ths turn into water vapor and become clouds? Cant spell Enviormentalist with out the MENTAL
The seals need a better press agent. “Polar bears drowning due to lack of ice is great news for seals!” Hmm - I wonder if it was the polar bears that were behind the anti clubbing baby seals movement years ago? More seals for the bears to eat!
A glacier could never raise the global sea level 2 feet, and some high school math could prove that.
It would be like adding a drop of water to a swimming pool.

Ever notice how the dumber a person is, the more fervently they believe in globull warming?
Is Sara and her warming cohorts trying to tell us warmer ocean currents around the south pole—at depth—are so warm that they’re rapidly melting ice ? under near freezing water ? Who’s paying your salary ? Bunk, up your ass.
The article also says “floating”, which negates the whole premise because of the aforementioned ice-cube theory of displacement.
Furthermore, a world map shows Florida’s size as a rounding error when compared to the world’s oceans.
I think I read today that Antartica recorded extremely low temps last winter.-—minus 60° day and night. More snow, more ice, less liquid ocean.
Go pound sand. It’s too bad no one will be around to witness their humiliation when all is proven wrong, but that’s their scam, isn’t it ?
Sea levels began to rise 18k years ago at the end of the last glacial period. They have risen about 135 meters since then which is an average of 7.5 millimeters per year. That is an average of 750 mm per century (29.5 inches) which is far more than the average over the last century. As the chart shows most of that rise was over about 8k years ago.
From 1880 to 2000 sea level rose about 20 cm or just under 8 inches. Far less than the nearly 30 inches per century average over the last 18,000 years.
The most recent data from NASA shows a decline in sea level.
Inconvenient: NASA shows global sea level…pausing, instead of rising
