Shobita Parthasarathy spoke to NewScientist about a recent geoengineering research conference that gathered scientists and policy experts to discuss the creation of a voluntary set of standards to guide international ‘planetary rescue plan’ research in the event of catastrophic global warming. Policy experts at the conference encouraged geoengineers to share research plans with the public before engaging in large scale testing of projects with a potential global impact. Just running tests sends a signal that scientists are interested in a future for geoengineering, Parthasarathy told NewScientist. "The intention is to expand the process. The path will have been set."
