Geoengineering Climate Change
Even climate activists increasingly recognize that the lofty rhetoric of the global agreement to reduce greenhouse-gas emissions, concluded in Paris just over a year ago, will not be matched by its promises’ actual impact on temperatures. This should make us think about smart, alternative solutions. But one such alternative, geoengineering, is a solution that many people refuse to entertain.
Geoengineering means deliberately manipulating the Earth’s climate. It seems like something from science fiction. But it makes sense to think of it as a prudent and affordable insurance policy.
