Steven, New York bills itself as the financial capital of the world. Very little of the capital raised there however is going into transitioning from a fossil fuel-free economy and therefore to the city's salvation.
A University of Calgary study suggests that 4 meters of sea level rise is already baked in, even if we stop adding CO2 to the atmosphere immediately, which of course isn't about to happen.
I submit no amount of adaptation is going to save Wall Street from this much rise since it is about the height of the maximum surge that hit during Hurricane Sandy - absent any storm.
The big driver for sea level rise is going to be icecap melting. There is the potential for 80 meters there. The poles are warming faster than anywhere and past evidence suggests they warm about 3 times more than the global average. The heat is collected in the tropical ocean and then flows in accordance with the second law of thermodynamics to the colder region. Often the mechanism for this is tropical cyclones. By moving this heat instead into the deep, the other major cold sink, you short-circuit this movement to the poles and the icecap melting. The coefficient of thermal expansion of sea water is also half at 1000 meters what it is at the surface so you reduce sea level rise that way as well. To get this power to market you have to electrolyze the sea water to produce hydrogen, which is as much a water carrier as it is an energy carrier, and bring this water/energy to shore, where it is reconstituted, you reduce sea level rise again.
As much energy as is currently being derived from fossil fuels can be produce in this manner and thus you are transitioning away from fossil fuels even as you mitigate the impact of their burning.
It would be in the interest of Wall Street, and Columbia University to get behind the only solution that has a chance of stopping a rise of 4 meters let alone far more.
