NEW YORK - Mayor Michael Bloomberg today unveiled a new study on climate change at the Brooklyn Navy Yard.

The study suggests that by the 2050s, 800,000 people could be living in a flood zone that would cover a quarter of the city. According to the study, done after Superstorm Sandy, New York City could have as many 90 degree days as Birmingham, Ala. currently has.

In response to the findings, the city has created PlaNYC as a way to prepare for future natural disasters. Some key initiatives included in the plan include permanent levees, the creation of more sand dunes on wider beaches and working with the federal government to decrease the price of flood insurance.

Mayor Bloomberg says that effective July 1, $50 million from the City Council's budget will fund PlaNYC in addition to state and federal funding.
