Summary

The Paris Agreement aims to limit the global temperature rise to 1.5° to 2°C above preindustrial temperature, but achieving this goal requires much higher levels of mitigation than currently planned. This challenge has focused greater attention on climate geoengineering approaches, which intentionally alter Earth's climate system, as part of an overall response starting with radical mitigation. Yet it remains unclear how to govern research on, and potential deployment of, geoengineering technologies.
