Is must be asked — what sort of “ambitious measures” could possibly hold back the ocean? From The Raw Story:

Sea-level rise is occurring much faster than scientists expected – exposing millions more Americans to the destructive floods produced by future Sandy-like storms, new research suggests.

Satellite measurements over the last two decades found global sea levels rising 60% faster than the computer projections issued only a few years ago by the United Nations’ Intergovernmental Panel on Climate Change.

The faster sea-level rise means the authorities will have to take even more ambitious measures to protect low-lying population centres – such as New York City, Los Angeles or Jacksonville, Florida – or risk exposing millions more people to a destructive combination of storm surges on top of sea-level rise, scientists said…
