Defending New York City Against Hurricanes With Barriers

Thursday, February 28, 2013

In the aftermath of Hurricane Sandy, there have been a number of proposals to waterproof the New York waterfront. One idea is to erect large—and expensive—storm surge barriers. Alex Marshall, author of "The $5.9 Billion Question" in the February issue of Metropolis magazine and author of the new book The Surprising Design of Market Economies, Malcolm Bowman, distinguished professor of oceanography at SUNY Stonybrook, Piet Dircke, and global director for water management for ARCADIS, talk about the proposals.

Dikes & barriers have been successfully used when sea level was constant. An uncertain rate, but certain occurrence of sea level rise is a completely different challenge. And what happens to areas just outside of these barriers?

Shall we burn trillions of barrels of diesel to build these fallible barriers when burning fossil fuel is the root of the problem? Sounds like sheer folly to me.
