Rising sea levels pose a far bigger eco threat than previously thought. This week's climate change conference in Copenhagen will sound an alarm over new floodings - enough to swamp Bangladesh, Florida, the Norfolk Broads and the Thames estuary.
"It is now clear that there are going to be massive flooding disasters around the globe," said Dr David Vaughan, of the British Antarctic Survey. "Populations are shifting to the coast, which means that more and more people are going to be threatened by sea-level rises."
