FILE- In this Tuesday, June 11, 2013, file photo, New York City Mayor Michael Bloomberg speaks while a map of the projected 2050s 100-year flood plain of New York City is displayed in New York. The projections show a city where by the 2050s, 800,000 people could be living in a flood zone that would cover a quarter of the land, and there could be as many 90-degree days as is now normal for Birmingham, Ala.
