What the collapse of Antarctica’s ‘doomsday’ glacier could mean for the world ... ANTARTICA - 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 have a significant coastline-changing impact. For context, since 1900 there’s been an approximate 20cm rise in sea-levels, an amount that is already forcing some 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 key 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 seve...
