Wednesday marked two years since Superstorm Sandy, and New York has been preparing for the possibility of another natural disaster in the future.

News 12 meteorologist Mike Favetta spoke with climate expert Megan Lincoln, of Swiss Re, about how the city can best prepare.

Lincoln says that a storm in 1821 that struck the Metropolitan area would cost $100 billion in damages today.

She says the best way the city can prepare for a natural disaster is to be ready at the sub-federal level, between local and city governments. Lincoln says it is not wise to wait for the federal government to approve funds when they are needed quickly.

She also says beach and dune replenishment is important to fight storm surges.
