    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.

    [...] “We think that geoengineering of glaciers could delay much of Greenland and Antarctica’s grounded ice from reaching the sea for centuries, buying time to address global warming,” the scientists write in the current issue of Nature. “Geoengineering of glaciers has received little attention in journals. Most people assume that it is unfeasible and environmentally undesirable. We disagree.”
