Today journalist McKenzie Funk tells Fresh Air about the entrepreneurs looking to cash in on climate change. In the interview he talks about the massive gates designed to protect cities in the event of a large storm surge:
[In the Netherlands] It’s called the Maeslant Storm Surge Barrier (above) and it’s these two Eiffel Tower-sized gates. They swing closed and close the Port of Rotterdam, which is the most important port in all of Europe, it’s where most of the oil and gas come in and it’s where most of everything leaves. They have a huge computer warning system that says, ‘OK, the tides are surging. We need to close the barrier.’ And that actually happened for the second time in history late in 2013, just a few months ago.
… It basically swings closed from both sides and they meet in the middle, these two massive gates and then this piece comes up from below and it closes off the entire harbor — water can’t get in, water can’t get out.
… [The proposed gates to protect Manhattan] would go across the narrows, the area below the Verrazano Bridge. … The storm comes, warning system warns, and the gates swing closed and Manhattan is protected. … We’re talking Statue of Liberty [height] . … Prices are pretty variant at the moment, but [it’s] in the order of $10 billion.
