According to a report from the New York City Resiliency Initiative, 88% of the city’s steam generating capacity, 53% of the in-city electric generation capacity, 37% of transmission substation capacity, and 12% of large distribution substation capacity currently lie within the 100-year floodplain.   However, the picture is actually much worse than that, because climate change is accelerating flooding events, making 100-year floods occur much more frequently.  Today, a “100-year storm” means a surge flood of about two meters in New York City.  A “500-year storm” indicates three-meter-high surge floods. Both scenarios would easily top Manhattan’s seawalls, which are only 1.5 meters high.  But according to climate modeling by researchers at MIT and Princeton University, the greenhouse effect will soon cause two-meter surge floods every three to 20 years, and three-meter floods every 25 to 240 years in New York City.  In other words, as sea levels rise, precipitation rate...
