Might research on solar geoengineering resemble its broader “free-driver” dynamics?

By Gernot Wagner

It’s called “re-search” for a reason. You search, you search, and you search again. It also means that researchers will naturally tackle the low-hanging fruits first. Unearthing the harder bits just takes time. That’s the natural flow of things, and solar geoengineering research is unlikely to be different.

The broader implications for solar geoengineering and its possible role in climate policy, however, might well be.

Contrast solar geoengineering with cutting emissions in the first place. The Economics 101 analysis of emissions...
