“Some problems have easy solutions. If we feel sweaty, we’ll head for the shade. If our soup’s too hot, we’ll blow on it. If a room’s too stuffy, we’ll open a window. But what are the options when the planet grows too warm?”
“Some researchers propose tinkering with the planet’s climate in several big ways. Adopting any of their proposed projects would be a step so major that many of those same experts hope people will never do it. But if successful, this geoengineering could soften — if not reverse — global warming. The risk: If unsuccessful, geoengineering might make things worse.”
Do we need to try it?
