(Bloomberg) — The warming Atlantic Ocean has raised the risk of another Hurricane Sandy.

And still, trillions of dollars of real estate and infrastructure near the shores of New York City and northern New Jersey remain vulnerable to devastation.

A storm-surge barrier similar to those in Louisiana and parts of Europe might protect the area, but politicians have questioned its $30 billion cost, effectiveness and environmental impact. A group of scientists, planners and property owners is urging the U.S. Army Corps of Engineers to accelerate its study of the project. It may take another hurricane to speed up the process.

Danger of rising sea levels increases

“The danger is increasing as the sea level rises,” said Malcolm Bowman, an oceanographer at the State University of New York at Stony Brook, who is among the group. “It won't take a monster storm like Sandy to devastate the region.”
