Summary
In this episode, Dakota Gruener of Reflective walks me through her organization's new project, which maps the gaps in our scientific understanding of stratospheric aerosol injection — currently the leading candidate for directly cooling the planet. We get into what we don't know (including a factor-of-two disagreement on basic aerosol physics), who's already doing this without oversight, and the unsettling governance question of who controls the Earth's thermostat once humanity has grabbed it.
