If we have to hack the planet, we could at least do it with some finesse. Some of the problems with geoengineering could be fixed by targeting specific regions of the planet, rather than cooling everywhere equally.

A rough modelling study offers a crude blueprint for how to save the Arctic ice cap, but raises questions about who decides which areas to save.

Devised to stop climate change if attempts to cut greenhouse gas emissions fail or are insufficient to cool the planet, geoengineering schemes range from sucking carbon dioxide out of the air to “sunshades” that block incoming sunlight.
