After Sandy

More than six months after Super Storm Sandy hit America’s East coast, Angela Saini reports from New York where scientists, engineers and State officials have gathered to debate how best to prevent future flooding wreaking havoc on that scale again. One option is to build a giant storm protection barrier. But not everyone is convinced that the risk of another Sandy is worth its 10 billion dollar price tag. A cheaper solution is to restore the coastline to its natural State, which would help to slow down the flow of water along the Hudson, should another super storm occur. But something like Sandy is, say sceptics, a highly unusual event - the last time the East Coast was hit with something similar was in 1821. However, with rising sea levels predicted, storms could become more frequent and others insist that the time to act is now, to save the people and homes of New York.
