And, scientists are trying to determine why. I suggest they read WUWT and learn it's not melting at all but rather growing rapidly, as the earth cools. /s

Scientists Are Racing to Figure Out Why This Giant Glacier in Antarctica Is Melting So Fast | Live Science

In the next few days, scientists will lower the torpedo-shaped robot, dubbed Icefin, into a nearly 2,000-foot-long (600 meters) borehole in the ice of Thwaites Glacier in West Antarctica....

The Thwaites Glacier covers more than 74,000 square miles (192,000 square kilometers) — an area larger than Florida — and is more than 900 miles (1,500 km) from the nearest U.S. and British Antarctic research bases. It's one of Antarctica's fastest-melting glaciers, having lost an estimated 595 billion tons (540 billion metric tons) of ice since the 1980s. Observations indicate that the glacier is now melting even faster than before, and scientists want to find out why.

My guess is warm water at the "grounding line" is eating that thing from the bottom up.

(German text translated/edited by P. Gosselin)
The ice in Antarctica, how is it doing? Is it melting, is it growing? In the following we wishto present the latest literature on the subject. There is a lot to report.
Fasten your seat belt, there’s a lot to cover.
Let’s start with the temperature development because along with snowfall, this is the most important control factor for Antarctic inland ice.
At NoTricksZone, Kirye shows ten coastal stations of Antarctica. None have been warming over the past 10 years. An example followws

And here’s the temperature development of the entire Antarctic according to UAH and RSS satellite measurements (from Climate4You, via NoTricksZone):

According to Clem et al. 2018, East Antarctica has cooled over the last 60 years, while West Antarctica has warmed. The authors establish a connection with the SAM ocean cycle, the Southern Annular Mode. Euan Mearns also deals with the temperature development of Antarctica during the last decades. . . .

Another junk site cited. Makes me wonder if deniers ever read something credible.

let's see if I got this right a glacier with 192,000 square kilometers has lost 540 billion metric tons of ice since 1980.
1 cubic kilometer of water is 1 billion metric tons, so spreading 540 billion metric tons of ice over 192,000 square kilometers if the glacier,
means the loss over 40 years would equal to 540/192,000= .00281 kilometers, or about 2.8 m.
I guess that does not sound as scary as "having lost an estimated 595 billion tons (540 billion metric tons) of ice since the 1980s."

I did some searches. There is a 2014 Science article that speaks of the grounding line being 600 meters below sea level. If it's heat related, it would be because of volcanic action.

The present Thwaites grounding line—the location where ice reaches the ocean and goes afloat—rests on a coastal sill ~600 m below sea level

Yet another climate change thread gets swarmed by the same 3-4 posters with their usual pseudoscience citations.

This is just another "The Sky is Falling" thread.

All peer-reviewed. Graphs are from NOAA.
The problem is fear of the data among AGW alarmists.

And there they are right on cue. :lamo

You guys remind me of a lawyer. Take actual facts and twist them to fit your agenda (in this case: antigovernment worldview.)
 
Yup, posting large images and long form citations without context... just another typical denier-swarmed thread.
 
Jack did his best to conspiracy-blog-spam the thread out of existence.
 
OK, Antarctica has an average annual precipitation of 200 mm, and the Chicken Littles are going to fear a glacier that loses 70mm annual?

OK...

You just showed fear......

:mrgreen:
 
That I find funny is the Thwaites Glacier is only classified as a glacier because its base is on solid ground. Only a very small percentage the glacier base is above sea level. It is technically an iceberg tongue. So it isn't going to react like actual glaciers that are above sea level.

I might possibly have spotted a possible reason;

It's the tongue of ice sticking out into the ocean....

Unlikely agenda since I spent my career in government. Learn first, then post.
