Per news reports I've seen in the UK, MTA commissioned a report on mega-hurricane disaster of Sandy proportions a couple of years ago, but hadn't upped their maximum anticipated disaster to match -- Sandy exceeded their "worst case" assumptions, and even after they pump everything dry and repair the damage, Sandy-proofing the subway against a future hurricane of identical proportions will probably cost billions.

The energy density of a hurricane is staggering, and it's driven by humidity and temperature gradients over an area the size of a sub-continent. It's not immediately obvious that we can do anything about this short of large-scale geoengineering to reduce global energy inputs. (It's not "global warming" so much as "global absorbing-more-energy-in-a-dynamic-system", resulting in wilder fluctuations and more extreme weather events. Such as Sandy.)
