Antarctica Is Losing a Flabbergasting Amount of Ice
Antarctica Is Losing a Flabbergasting Amount of Ice
Researchers are concerned about a huge chunk of ice larger than Mexico failing to refreeze as temperatures drop in Antarctica.

Indeed. Antarctic sea ice extent is at record-breaking lows.
"Chunk of ice", "failing to refreeze"
Wut?
Yeah, that wording is clunky. I guess, according to the article, the ice is known to melt and return in a cyclical pattern every year. This year almost a million square miles of ice did not form as expected.
Right now, it's winter in the southern hemisphere. Sea ice should be expanding around Antarctica, but it's doing so much less than previous years. It's so bad there's a chance there won't be any sea ice by the time it's mid summer there, in December/January/February. If that happens, there's nothing to stop the land glaciers from slipping into the sea and significantly raising sea levels worldwide. Could be like 10 feet of sea level rise depending on what happens. (Thwaites Glacier has been named in many articles as especially precarious and able to contribute 10 feet on its own.)
I share your concern over the risks posed by the loss of sea ice. However, per the Thwaites Glacier Collaboration, even if the entire glacier were to collapse it would amount to around a 65cm rise of sea level, and the majority of that would come in the 22nd and 23rd century.

This is the best summary I could come up with:
Researchers are increasingly concerned about a huge chunk of ice — larger in area than Mexico — failing to refreeze as seasonal temperatures drop in Antarctica.
"Unprecedented is a word that gets bandied around a lot, but it doesn’t really get to just how shocking this is," Hobbs, a sea ice scientist at the University of Tasmania, told The Guardian.
"There’s a sense that something weird is going on," Walt Meier, a senior scientist at the National Snow and Ice Data Center at the University of Colorado, told The Guardian.
We've seen strong declines in the amount of Antarctica's sea ice since 2016, with experts still debating how much human activity is contributing to the trend.
Concrete evidence is proving hard to come by, due to the complexity of the continent and its surrounding ocean's dynamics.
"The Antarctic system has always been highly variable," Ted Scambos, a glaciologist at the University of Colorado Boulder, told CNN.

I just created the summary! You can find it at https://lemmings.world/comment/972741.
There's supposed to be quite a few things down in that ice. Some encased. Some not so much. Some natural. Some not so much.
Don't dig up the Stargate, it never helps.
Some natural. Some not so much.
What the hell is unnatural there?
Well there is supposed to be a 4-sided pyramid (similar to Gaza but bigger) and also some kind of large underground base for UAP.
What is there? I dunno. Sometime after Operation Highjump, It was decided that folks like us are no longer permitted to go there. It could be an intergalactic puppy farm for all I know.
But I do like the mystery.

I see a black sea and I want it painted white....

if ice fails to re-freeze, it's not really ice anymore, is it?
was this generated by AI or something? such a shit article
There’s still ice in Antarctica? I thought we were supposed to have melted it all by now.
to see how much less ice there is than usual
