Eastern Antarctica, often referred to as the “extreme frontier of global warming” is once again in the ecological hazard headlines.
A few weeks ago, temperatures in eastern Antarctica hovered between 50F and 90F above normal, causing scientists to worry.
One or two weeks after the unnatural rise in temperature, the eastern Antarctic Conger Ice Shelf (1,200 sq km) completely collapsed, and two more glaciers collapsed in the same week.
Complete collapse of East Antarctica’s Conger Ice Shelf (~1200 sq. km) ~March 15, seen in combo of #Landsat and #MODIS imagery. Possible it hit its tipping point following the #Antarctic #AtmosphericRiver and heatwave too? #CongerIceShelf #Antarctica @helenafricker @icy_pete https://t.co/7dP5d6isvd pic.twitter.com/1wzmuOwdQn

The Breakthrough National Center for Climate Restoration in Melbourne, said early IPCC reports would make Antarctica stable for a thousand years.
Then, in 2007, Richard Alley dropped the bomb saying that it was already 100 years ahead of the melting glacier. That is, he says, the iceberg melting event that should have occurred in 100 years has already occurred.
In fact, Antarctica has a melting pattern that first broke the climatic model, breaking the pattern of a few centuries ago, and then the period pattern of decades.
Scientists fear that no one can predict what the outcome will be and who knows what will happen.
I suspect Totten Glacier mostly got nuked with warm snow during the mid-March Antarctic atmospheric river. The glacier did also loose a little ~14km^2 snaggletooth at its calving front, not a big deal though, maybe unrelated. #Sentinel1 @sentinel_hub pic.twitter.com/LEV4bdLmwq

Eastern Antarctica, in contrast to its most vulnerable first cousins, Western Antarctica and the Antarctic Peninsula, is said to be the solid, rock-solid 1 to 3-mile-thick iceberg of the United States.
The day after March 15, the eastern Antarctic Conger Ice Shelf completely collapsed. This decline occurred following a record temperature of 40C + warmer than the seasonal norms.
Helen Amanda Bricker, an avalanche researcher at the Scripps Arctic Center, said three glacier collapse shows in March, 1. Conger Ice Shelf. 2. Cleanser Ice Shelf, says another small collapse that occurred on the larger Totten Glacier. Thus by the middle of the century, sea level is said to have risen by a couple of feet.

“We’ll see bigger, bigger glaciers and surfaces break up than this,” said Professor Matt King. Enough to raise global sea levels sharply … The speed of the breaking of the Conger Glenzer reminds us that things can change quickly… Our carbon emissions will have an impact on Antarctica, and this impact on Antarctica will affect other parts of the world faster than we think. ” Warns that.
