The melting of Antarctica's vast Thwaites Glacier will increase “inexorably” this century, potentially destabilising the entire West Antarctic Ice Sheet, leading to its eventual collapse, scientists have warned.
Thwaites, which is roughly the size of Britain and more than 2km thick in places, is nicknamed the Doomsday Glacier because it represents more than half a metre of global sea level rise potential and could destabilise neighbouring glaciers that have the potential to cause a further three-metre rise.
The world’s widest glacier is currently losing about 50 billion more tonnes of ice than it receives in snowfall, in an accelerating process first observed in the 1970s.
Researchers at the International Thwaites Glacier Collaboration, a project that includes researchers from the British Antarctic Survey, the US National Science Foundation and the UK’s Natural Environment Research Council, wanted to know how rapid that melt has become.
Using a small torpedo-shaped robot, researchers studied the underside of Thwaites, discovering a thin layer of cold water insulating the glacier. But in areas where the parts lift off the seabed and the ice begins to float, tidal action is pumping warmer seawater, at high pressure, as far as 10km under the ice. The process is disrupting that insulating layer and is likely to significantly speed up how fast the grounding zone – the area where the glacier sits on the seabed – retreats. A similar process has been observed on glaciers in Greenland.
Some computer models suggest that reductions in greenhouse emissions under the 2015 Paris Agreement may still slow the pace of runaway loss, extending its collapse well past the end of this century. But the outlook remains “grim”, according to an International Thwaites Glacier Collaboration report released on Friday.
Thwaites has been retreating for more than 80 years but that process has accelerated in the past 30, said Rob Larter, a marine geophysicist who contributed to the research. “Our findings indicate it is set to retreat further and faster.” Other dynamics that are not currently incorporated into large-scale models could speed up its demise, the new research shows.
Antarctica sea ice study – in pictures
In a worst-case scenario, which would see the formation of 100-metre-or-higher ice cliffs at the front of Thwaites that then rapidly calve off as icebergs, sea levels could rise by tens of centimetres this century. However, the researchers said it is too early to know if such scenarios are likely.
The researchers found the glacier has retreated much faster in the past than what is seen today. Ridges show where it retreated more than 2km a year several centuries ago – twice as fast as the current rate. But climate change could make its recovery more unlikely this time.
Heavy snowfalls regularly occur in the Antarctic and help replenish ice loss. “The problem though is that we have this imbalance: there is more ice loss occurring than snowfall can compensate for,” said Michelle Maclennan, a climate scientist with the University of Colorado Boulder.
Increased moisture in the planet’s atmosphere, caused by global warming evaporating ocean waters, could result in more Antarctic snow – at least for a while. At a certain point, though, that is expected to switch over to rain and surface melting on the ice, creating a situation where the glacier is melting from above and below. How fast that happens depends in part on nations’ progress to slow climate change, say scientists.
Earlier this year, scientists discovered Thwaites' retreat began in the 1940s, after an extreme El Nino weather event. The US study found the significant rate of melting began then, about the same time the retreat of the nearby Pine Island Glacier started, probably due to an extreme El Nino that warmed the western Antarctic.

Five famous companies founded by teens
There are numerous success stories of teen businesses that were created in college dorm rooms and other modest circumstances. Below are some of the most recognisable names in the industry:
- Facebook: Mark Zuckerberg and his friends started Facebook when he was a 19-year-old Harvard undergraduate.
- Dell: When Michael Dell was an undergraduate student at Texas University in 1984, he started upgrading computers for profit. He starting working full-time on his business when he was 19. Eventually, his company became the Dell Computer Corporation and then Dell Inc.
- Subway: Fred DeLuca opened the first Subway restaurant when he was 17. In 1965, Mr DeLuca needed extra money for college, so he decided to open his own business. Peter Buck, a family friend, lent him $1,000 and together, they opened Pete’s Super Submarines. A few years later, the company was rebranded and called Subway.
- Mashable: In 2005, Pete Cashmore created Mashable in Scotland when he was a teenager. The site was then a technology blog. Over the next few decades, Mr Cashmore has turned Mashable into a global media company.
- Oculus VR: Palmer Luckey founded Oculus VR in June 2012, when he was 19. In August that year, Oculus launched its Kickstarter campaign and raised more than $1 million in three days. Facebook bought Oculus for $2 billion two years later.
