A Big-Sky Plan to Cool the PlanetPumping aerosols into the stratosphere may
buy us more time, but it’s no substitute for cutting carbon emissions—and
we still don’t know enough to do it responsibly.

Seriously addressing climate change means cutting carbon emissions and,
ultimately, reducing the carbon already in the atmosphere. There’s no way
around it. Another type of intervention, however, is increasingly garnering
attention: solar geoengineering, that is, cooling the planet by making it
reflect back more of the sun’s rays. It’s not a permanent solution to
climate change, and it carries worrisome environmental and political risks
of its own, but it’s an idea worth exploring.
