I pointed out that New York had a much bigger storm two centuries ago, and Huffington Post quickly deleted it. This is information which the public is not entitled to know, because it wrecks the basis of the global warming religion.
In 1821, stunned colonial New Yorkers recorded sea levels rising as fast as 13 feet in a single hour at the Battery. The East River and Hudson Rivers merged over Lower Manhattan all the way to Canal Street. According to Coch, the fact that the 1821 storm struck at low tide “is the only thing that saved the city.”
In the event of a direct hit by a category-3 hurricane, surge maps show that the Holland and Battery Tunnels will be completely filled with sea water, with many subway and railroad tunnels severely flooded as well. The runways of LaGuardia and JFK airports will get flooded by 18.1 and 31.2 feet of water, respectively.
