Unavoidable future increase in West Antarctic ice-shelf melting over the twenty-first century Abstract Ocean-driven melting of floating ice-shelves in the Amundsen Sea is currently the main process controlling Antarctica’s contribution to sea-level rise. Using a regional ocean model, we present a comprehensive suite of future projections of ice-shelf melting in the Amundsen Sea. We find that rapid ocean warming, at approximately triple the historical rate, is likely committed over the twenty-first century, with widespread increases in ice-shelf melting, including in regions crucial for ice-sheet stability. When internal climate variability is considered, there is no significant difference between mid-range emissions scenarios and the most ambitious targets of the Paris Agreement. These results suggest that mitigation of greenhouse gases now has limited power to prevent ocean warming that could lead to the collapse of the West Antarctic Ice Sheet.

Even if all manmade CO2 etc emissions were to stop right now it is too late to stop the melting of the West Antarctic Ice Sheet and 5m of sea level rise this century. Doubt the news re Greenland ice sheet is any better, or the Himalayan IS.

Guardian article some might find easier reading:

Lees mumbled something then the idiot ruining Environment and so OzPol mumbled something—how thick the Antarctic ice sheet is, how long it would all take to melt.

Obviously the clown didn’t even read the simplified Guardian article. Reading isn’t really his thing, being talked down to by clowns on YouTube is more his thing.

Yet he might ascertain before opening his big idiotic mouth as to what is being discussed.

The WEST ANTARCTIC ICE SHEET and the glaciers making up the WAIS. With the warming Antarctic Ocean the ice shelves that act as the brakes of the glaciers in the WAIS are melting. They melt and the glaciers behind them will slip into the sea, raising sea levels five metres.

This melting and the glaciers sliding into the sea are guaranteed no matter what will be done re emissions this decade, this century.


Really does seem that seeding the stratosphere with aerosols is the one thing we can do, fraught with risks and uncertainties though it is, to stop runaway global warming and sea level rise.

Oh cute, Jaye joins in.

If there is anyone on OzPol less informed than Booby and lees it has to be Jaye.

The laughs never stop.

Oh god, an idiot asks me if I called him an idiot. Laff!

The idiot has only added like 10K posts since being made the Mod of what was Environment. Relationshits has doubled the number of posts in about the same time.

In terms of number of posts then the idiot is performing very poorly.

What about quality of posts? The idiot has not posted about the environment or ecology once! Quality of the dreck posted there—crap!

Environment should have 200,000 posts by now!


The clown responded to my post on the inevitable loss of the WAIS this century—by talking about the Antarctic Plateau. How stupid can you be? Clown did not even TRY to read my post.
