Quickening climate change in the Arctic including a thaw of Greenland’s ice could raise world sea levels by up to 1.6 meters by 2100, an international report showed on Tuesday.

Such a rise — above most past scientific estimates — would add to threats to coasts from Bangladesh to Florida, low-lying Pacific islands and cities from London to Shanghai. It would also, for instance, raise costs of building tsunami barriers in Japan.
