The NYC transportation system is all but come to a halt. No one knows the condition of the electrical infrastructure.  As the NYT explains today the City had been warned about this possibility/probability for years.

For nearly a decade, scientists have told city and state officials that New York faces certain peril: rising sea levels, more frequent flooding and extreme weather patterns. The alarm bells grew louder after Tropical Storm Irene last year, when the city shut down its subway system and water rushed into the Rockaways and Lower Manhattan.

On Tuesday, as New Yorkers woke up to submerged neighborhoods and water-soaked electrical equipment, officials took their first tentative steps toward considering major infrastructure changes that could protect the city’s fragile shores and eight million residents from repeated disastrous damage.

Gov. Andrew M. Cuomo said the state should consider a levee system or storm surge barriers and face up to the inadequacy of the existing protections.

“The construction of this city did not anticipate these kinds of situations. We are only a few feet above sea level,” Mr. Cuomo said during a radio interview. “As soon as you breach the sides of Manhattan, you now have a whole infrastructure under the city that fills — the subway system, the foundations for buildings,” and the World Trade Center site.

A few years ago the Weather Channel had a special on this very possibility.  Now as the sea level rises and the storms become more intense that possibility became a probability.  So what should be done?  Rebuilding followed by billions in levees and floodgates to protect from a future event?     Or should certain areas simply be abandoned?  Back in 2005 I suggested that New Orleans should be given back to the sea.  A Katrina scenario had also been predicted.

After rising roughly an inch per decade in the last century, coastal waters in New York are expected to climb as fast as six inches per decade, or two feet by midcentury, according to a city-appointed scientific panel. That much more water means the city’s flood risk zones could expand in size.

“Look, the city is extremely vulnerable to damaging storm surges just for its geography, and climate change is increasing that risk,” said Ben Strauss, director of the sea level rise program at the research group Climate Central in Princeton, N.J. “Three of the top 10 highest floods at the Battery since 1900 happened in the last two and a half years. If that’s not a wake-up call to take this seriously, I don’t know what is.”

So when is it going to become impossible to mitigate the threat?
