Geoengineering, the use of human technologies to alter the Earth's climate system — such as injecting reflective particles into the upper atmosphere to scatter incoming sunlight back to space — has emerged as a potentially promising way to mitigate the impacts of climate change. But such efforts could present unforeseen new risks. Scientists outline how the current deadlock on governance of geoengineering research poses real threats to the sound management of climate risk. Their article advances concrete and actionable proposals for allowing further research -- but not deployment -- and for creating scientific and legal guidance, as well as addressing public concerns.
