A New Study Says Solar Geoengineering Could Save the Oceans From Heat Waves. The Question Is Which Oceans.

A Michigan State University study published this week in Environmental Research Climate finds that stratospheric aerosol injection could shield up to 75 percent of the world's oceans from marine heat waves under an aggressive deployment scenario. The other 25 percent, the study finds, would still face hotter and longer ones. The geography of protection is the part the climate community now has to negotiate.
