As it is becoming increasingly unlikely that drastic emissions reductions will avert accelerated climate change, humans will have to look for ways to ease the impacts of a warming planet. Chief among them are rising sea levels, which will threaten the livelihoods of millions of coastal dwellers around the world. In the journal Nature, a group of scientists outline how three proposed engineering projects in Greenland and Antarctica could stave off glacial melting. The authors make a convincing case that the potential risks of glacial geoengineering, if feasible, would be smaller than letting accelerated glacial melting run its course.
