![Rapid ice melt in west Antarctica is 'inevitable' - even with emissions cuts](https://cdn.magzter.com/1588175106/1698100951/articles/AYUCkV-K41698106464803/RAPID-ICE-MELT-IN-WEST-ANTARCTICA-IS-INEVITABLE-EVEN-WITH-EMISSIONS-CUTS.jpg)
The ice sheet of west Antarctica would push up the oceans by 5 metres if lost completely. Previous studies have suggested it is doomed to collapse over the course of centuries, but the new study shows that even drastic emissions cuts in the coming decades will not slow the melting.
The analysis show s the rate of melting of the floating ice shelves in the Amundsen Sea will be three times faster this century compared with the last, even if the world meets the most ambitious Paris agreement target of keeping global heating below 1.5C above pre-industrial levels.
Losing the floating ice shelves means the glacial ice sheets on land are freed to slide more rapidly into the ocean. Many millions of people live in coastal cities that are vulnerable to sea level rise, from New York to Mumbai to Shanghai, and more than a third of the global population lives within 62 miles (100km) of the coast.
