Many of the world’s major cities, including Bangkok, London, Miami and New York, could be flooded by the end of the century, according to a new analysis of current temperatures in the Arctic region published in the journal Science.

By then, global temperatures will be an average of three degrees C. higher than now — or about as hot as it was nearly 130,000 years ago, when ocean levels were four to six metres higher.

“Probably our estimates of sea-level rise even five years ago were too small, too conservative,” Jonathan Overpeck, a University of Arizona researcher who helped lead the study, was reported as saying.
