Greenland and Antarctica are both tracking the IPCC's worst-case climate warming scenario. Left unchecked, this will lead to an extra seventeen centimetres of sea level rise by 2100.
Professor Shepherd said: “Every centimetre of sea level rise leads to coastal flooding and coastal erosion, disrupting people’s lives around the planet.
“If Antarctica and Greenland continue to track the worst-case climate warming scenario, they will cause an extra 17 centimetres of sea level rise by the end of the century.
“This would mean 400 million people are at risk of annual coastal flooding by 2100.
