Dozens of the world's cities, including London and New York, could be flooded by the end of the century, according to research which suggests that global warming will increase sea levels more rapidly than was previously thought.

The first study to combine computer models of rising temperatures with records of the ancient climate has indicated that sea levels could rise by up to 20ft (6m) by 2100, placing millions of people at risk.

The threat comes from melting ice sheets in Greenland and Antarctica, which scientists behind the research now believe are on track to release vast volumes of water significantly more quickly than older models have predicted. Their analysis of events between 129,000 and 116,000 years ago, when the Arctic last warmed to temperatures forecast for 2100, shows that there could be large rises in sea level.
