Human Intervention in the Earth’s Climate: The Governance of Geoengineering in 2025+
Geoengineering, or climate engineering, is the umbrella term for large-scale technological interventions into the climate system that seek to counter some of the effects of global warming. Due to limited progress in reducing global greenhouse-gas emissions thus far, geoengineering has been increasingly investigated as a potential addition to the portfolio of climate responses. At this point, however, the shape and role that geoengineering will take in the future remain highly uncertain. In this report, we look 10 years ahead, at the year 2025, and present two scenarios of geoengineering’s possible evolution, with the goal of providing policy recommendations for its effective governance.
