As if the threat of much of the eastern seaboard ending up under water isn’t bad enough, a new study shows that the situation is even worse than previously thought.

As if the threat of much of the eastern seaboard ending up under water isn’t bad enough, a new study shows that the situation is even worse than previously thought.

While the specific dates for the complete engulfment aren’t predicted, the report says that the point of no return is quickly approaching for around 1400 coastal cities and towns.

That point is declared when areas have 50% of their current population living where the water levels are predicted to rise and flood.

It’s called the ‘locked-in date” and over 300 American cities have already reached theirs.

Among them are Miami Gardens, Hoboken, and Fort Lauderdale.

For cities on the locked-in track, measures much more dramatic than those currently agreed to by world leaders including President Obama are said to be needed.

According to the author of the study, more aggressive cuts in emissions could save a thousand cities from reaching their anticipated date of imminent demise.

If things carry on as they are Cambridge, Massachusetts – home to MIT and Harvard – will by locked-in by 2060. Miami could be considered a certain loss by as early as 2041.
