How a Massive Wall in Antarctica Could Hold Back Sea-Level Rise

Glaciers are mighty rivers of ice that can carry boulders on their backs and grind valleys into rugged mountain ranges. But now, scientists say that humans might need to think about trying to engineer these formidable forces of nature.

Propping up glaciers in the Arctic and Antarctic might be the most targeted — and, amazingly, the cheapest — way to slow sea-level rise in a warming world, according to a new paper in the journal The Cryosphere. A seawall, or even just a series of artificial seamounts for the glacier to get stuck against, could hold back unimaginable amounts of meltwater, the research suggests.
