We have heard a lot about Tuvalu disappearing under the waves. But Manhattan?

A new study published today shows that shifting ocean currents due to human-induced climate change will raise sea levels in New York by an additional 36 centimeters by the end of the century. 

That’s on top of the 15 cm due to thermal expansion of the oceans in our warming world.

Then there’s the impacts of melting ice sheets in Antarctica and Greenland, which scientists last week stated could double the IPCC predictions of only two years ago – to about a meter.

Let’s not forget another study published in February showing that the northern hemisphere will be preferentially impacted by melting in Antarctica – adding another 30% of sea level rise in places like New York.

Doing the latest math, that could total more than 180 centimeters (close to six feet) of sea level rise in the Big Apple by the end of the century. This sea level thing is starting to add up.

Guess what? Many parts of Lower Manhattan are only 150 centimeters above sea level. Some of the most expensive real estate in the world could be under water in only 90 years. That ironically includes the Marriott Marquis Hotel where the notorious Heartland Institute held their climate deniers gathering last week.
