Quite a bit of the very pricey treeless ape infrastructure along the coastlines stands to be washed away within a generation.

Probably not.

https://svs.gsfc.nasa.gov/31156/

"Research based on observations from the Gravity Recovery and Climate Experiment (GRACE) satellites (2002-2017) and GRACE Follow-On (since 2018 - ) indicates that between 2002 and 2023, Greenland shed approximately 270 gigatons of ice per year, causing global sea level to rise by 0.03 inches (0.8 millimeters) per year."

0.8 mm sea level rise per year isn't exactly impressive. Antarctica's floating ice shelves are even less of a worry - when they melt the sea level doesn't rise at all.

There is an anxiety that all this melting will lead to the land-based ice sheets sliding off inot the sea much faster, but that hasn't happened yet, and since all the action is under the ice sheet, we won't get much advance warning, Twits like you crying wolf isn't helpful.

ESA used the term 'alarming' not me, or didn't you notice?

Western Antarctica is where that gigantic ice mass sitting in a bowl on land threatens to raise sea level by a full 20 feet. On the ground scientific expeditions to the area have drilled the area to determine its dimensions more precisely than can be done via satellite, and, among other things, have determined the bowl is filling with warm water cresting its lip. Ultimately the water will float the threatening ice mass. Ice shelves had been stabilizing this mess, until recently that is. And anyone with half a brain should know dumping massive amounts of fresh water into the ocean is very much not a good thing.

But thanks for the moron's - eye- view of the situation anyway.

Sure. But they didn't say anything that equates to

The moron's eye-view is the one that touts 270 gigatons of ice melting per year as "alarming" when it corresponds to 0.8mm per year of sea level rise..

Wittering on about the threat posed by West Antarctic ice sheet might be intelligent, but that wasn't what you were doing.

It might make sense to worry about it when it does show some sign of moving, but that wasn't what you were doing.

Your problem is you absolutely cannot 'synthesize' any particular news or information release with what you should know has gone before.

I'd say 20 feet rise, which could happen very soon, will definitely wipe out the treeless ape coastal settlement.

I've been well aware that the West Antarctic ice sheet has been seen as a potential threat for years

https://www.theguardian.com/science/2016/mar/22/sea-level-rise-james-hansen-climate-change-scientist

dates from 2016 and I'd known about it before that and posted comments here to that effect before that,

> I'd say 20 feet rise, which could happen very soon, will definitely wipe out the treeless ape coastal settlement.

That is a moron's eye-view of the threat. What you don't seem to be able to get into your head is that we don't know when it is going to happen, and we aren't going to get a lot of prior warning. If you look at the end of the last ice age, when there was 120 metres of sea level rise, the fastest rises were about a 2.5 metres per century.

https://noc.ac.uk/news/global-sea-level-rise-end-last-ice-age

We are looking at a total of 10 metres if Greenland and the West Antarctic ice sheets both slide off. It's going to nasty when it happens but probably manageable.

This isn't the last ice age or any of your other '-ene' eras. If anything they're seeing a total disconnect between rates of modern climate change and similar events from the distant past. For practical purposes it's enough to know the catastrophic sea level rise will happen before civilization is ready and faster than they can cope with.

But the distant past still had a bunch of ice sheets and they had to melt before the oceans could rise. The fact that temperatures are currently rising faster than they did in the past doesn't make any difference to the thermal inertia of the ice sheets, and doesn't yet seem to have introduced any new modes of heat transfer.

> For practical purposes it's enough to know the catastrophic sea level rise will happen before civilization is ready and faster than they can cope with.

But we don't know that, and don't know enough to make any useful predictions. Your alarmist fantasies are the product of your undisciplined imagination.
