Irene-like storms of the future would put a third of New York City streets under water and flood many of the tunnels leading into Manhattan in under an hour because of climate change, a new state government report warns Wednesday.
Sea level rise due to climate change would leave lower Manhattan dangerously exposed to flood surges during major storms, the report, which looks at the impact of climate change across the entire state of New York, warns.
“The risks and the impacts are huge,” said Art deGaetano, a climate scientist at Cornell University and lead author of the ClimAID study. “Clearly areas of the city that are currently inhabited will be uninhabitable with the rising of the sea.”
Factor in storm surges, and the scenario becomes even more frightening, he said. “Subway tunnels get affected, airports – both LaGuardia and Kennedy sit right at sea level – and when you are talking about the lowest areas of the city you are talking about the business districts.”
The report, commisioned by the New York State Energy Research and Development Authority, said the effects of sea level rise and changing weather patterns would be felt as early as the next decade.
By the mid-2020s, sea level rise around Manhattan and Long Island could be up to 10 inches, assuming the rapid melting of polar sea ice continues. By 2050, sea-rise could reach 2.5ft and more than 4.5ft by 2080 under the same conditions.
In such a scenario, many of the tunnels – subway, highway, and rail – crossing into the Bronx beneath the Harlem River, and under the East River would be flooded within the hour, the report said. Some transport systems could be out of operation for up to a month.
The report, which was two years in the making, was intended to help the New York state government take steps now to get people out of harm’s way – and factor climate change into long-term planning to protect transport, water and sewage systems.
New York mayor Michael Bloomberg was so concerned that he went on to commission an even more detailed study of the city after receiving early briefings on the report.

In my opinion, Karl Rove’s monopolized the national conversation for far too long and now it’s his turn to listen. But that’s just me!
