The seas around New York are up 9 to 11 inches over the last century, and the new flood maps just released double the flood zone compared to the 1986 maps that they replace. That's stark enough. But the new maps don't even put in the new flood zone large areas that were inundated by Sandy. Wow!

Even without including all the area flooded by Sandy in the new flood maps, the soon to be adopted new maps put for the first time billions of dollars of property into a flood zone. Insurance rates for affected property could jump from $1,500 to nearly $10,000 per year.
The Federal Emergency Management Agency now intends to update the nation's flood maps every 5 years. Climate change and its already risen seas already are costing Americans tens of billions of dollars. As the seas continue to rise, flood zones will expand and costs will jump further. Denial does not make this go away!
