Antarctica’s ‘doomsday’ glacier: how its collapse could trigger global floods and swallow islands
December 22, 2021 by Climate To
The massive Thwaites glacier in West Antarctica contains enough ice to raise global sea levels by 65cm if it were to completely collapse. And, worryingly, recent research suggests that its long-term stability is doubtful as the glacier haemorrhages more and more ice.
Adding 65cm to global sea levels would be coastline-changing amounts. For context, there’s been around 20cm of sea-level rise since 1900, an amount that is already forcing coastal communities out of their homes and exacerbating environmental problems such as flooding, saltwater contamination and habitat loss.
But the worry is that Thwaites, sometimes called the “doomsday glacier” because of its keystone role in the region, might not be the only glacier to go. Were it to empty into the ocean, it could trigger a regional chain reaction and drag other nearby glaciers in with it, which would mean several metres of sea-level rise. That’s because the glaciers in West Antarctica are thought to be vulnerable to a mechanism called Marine Ice Cliff Instability or MICI, where retreating ice exposes increasingly tall, unstable ice cliffs that collapse into the ocean.
A sea level rise of several metres would inundate many of the world’s major cities – including Shanghai, New York, Miami, Tokyo and Mumbai. It would also cover huge swathes of land in coastal regions and largely swallow up low-lying island nations like Kiribati, Tuvalu and the Maldives....

Yep, a lot of halfwits don't care about it.Has there ever been a time in this forum where this thread is any more irrelevant? I can't think of it.
Nobody is caring about the glaciers.
Yep, a lot of halfwits don't care about it.
But it's all about who's not winning!
Only unserious people are obsessed with things like glaciers. Most have no real responsibilities in life. For a huge majority of the public, they are waaaaaay too busy to be concerned about silly shit like glacier melt.
The Glacier shelf is in the water already thus very little effect to sea level rise.
Yep, a lot of halfwits don't care about it.
I see that clipper wants to worry over a glacial shelf that is already in the water does that mean YOU are the halfwit who falls for a non-emergency media generated scaremongering.
Now that the usual climate gooks ran away quickly after their typical yearly worry over a glacier that isn't a threat to the planet was smashed what will they cry over their ice cubes in their Vodka drink?
