Should we dim the sun? The fight over solar geoengineering
Spraying reflective particles into the stratosphere could cool the planet fast and cheap. Supporters want research now; opponents warn it's a dangerous distraction with unknowable, planet-wide side effects.
The summary above is a neutral framing. Below, each side reports the same story in its own words — judge for yourself.
Proponents argue that with warming accelerating, we can't afford to ignore a tool that could cut temperatures quickly and buy time to decarbonise — so we should at least study it carefully rather than fly blind.
Opponents warn that dimming the sun could disrupt monsoons and harvests, can't be safely governed, risks sudden 'termination shock' if stopped — and distracts from the real job of cutting carbon emissions.
