If it did collapse, experts predict the huge ice mass would raise global sea levels by more than 9.8ft (three metres) \u2013 submerging entire coastal cities and communities.<\/p>\n
Climate Central’s Coastal Risk Screening Tool shows the areas around the globe that would be worst hit.<\/p>\n
Here in the UK, people living on the east coast of England would be impacted the most.\u00a0<\/p>\n
Coastal hubs including Hull, Skegness and Grimsby would be plunged underwater, while places as far inland as Peterborough and Lincoln would also become waterlogged.\u00a0<\/p>\n
So, is your hometown at risk?\u00a0\u00a0<\/p>\n

Here in the UK,\u00a0swathes of London would be affected. Several areas on the River Thames gleam red on the map, including Bermondsey, Greenwich, Battersea, and Chelsea (artist impression)<\/p>\n
To use the tool, simply set the water level at 9.8ft (three metres) and the areas that would be plunged underwater will appear in red on the map.<\/p>\n

Several areas on the River Thames gleam red on the map, including Bermondsey, Greenwich, Battersea, and Chelsea.<\/p>\n
While the east coast of England would be most affected, several towns and cities on the west coast are also in the firing line, according to Climate Central.<\/p>\n
Neighbourhoods on the outskirts of Weston\u2013super\u2013Mare, Newport and Cardiff would all be plunged underwater, alongside parts of Southport and Blackpool.<\/p>\n
Residents in Northern Ireland and Scotland can mostly rest easy though, with few areas set to be affected.<\/p>\n
