It’s been one year since Superstorm Sandy battered New York, and though we’re relieved to be enjoying dry weather today, experts are warning us not to become too complacent. “Sandy wasn’t the big one,” says Nicholas K. Coch, a professor of coastal geology at Queens College. Coch points out that by the time Sandy made landfall, it was already a post-tropical cyclone, and predicts that it’s only a matter of time before an even stronger storm hits the city.
