Can We Stop Coastal Flooding ???

Scientists have outlined plans to build a series of mammoth engineering projects in Greenland and Antarctica to help slow down the disintegration of the planet’s main glaciers. The controversial proposals include underwater walls, artificial islands and huge pumping stations that would channel cold water into the bases of glaciers to stop them from melting and sliding into the sea.

The researchers say the work – costing tens of billions of dollars a time – is urgently needed to prevent polar glaciers melting and raising sea levels. That would lead to major inundations of low-lying, densely populated areas, such as parts of Bangladesh, Japan and the Netherlands.

Although the concept is appealing, is this plan feasible? Recent infrastructure failures suggest it may not be, including these:

• the "ice wall" intended to immobilize radioactive leakage from the nuclear disaster at Fukushima is not working; and
• the US apparently can't even build a safe pedestrian bridge.
