New York City Mayor Michael Bloomberg announced the city's long-term strategy to deal with climate change today in a speech given at the Duggal Greenhouse in the Brooklyn Navy Yards. Bloomberg stated his resolve to "battle against climate change" without waiting for Washington.

Based on predictions from a panel of climate-change scientists, Bloomberg warned that the city will only become more vulnerable to the kind of flooding experienced during Hurricane Sandy. "In fact, we expect that by mid-century up to one-quarter of all of New York City’s land area, where 800,000 residents live today, will be in the floodplain."

To counter potential flooding, Bloomberg said the city has determined a number of protective measures. These include building up a dune system on the city's beaches, building offshore breakwaters, and creating wetlands to lessen waves on the South Shore of Staten Island and throughout Jamaica Bay.
Bloomberg also said the city plans to address the "backdoor flooding" that occurs around smaller waterways, including rivers and creeks:

"Today, we are proposing that several surge barriers be considered to shut these back doors. Building them will take years of design and construction work – but we can begin the process now."
