  • Definition of "geoengineering" are vague
    • Geoengineering refers to a broad set of methods and technologies that aim to deliberately alter the climate system in order to alleviate the impacts of climate change.
    • The potential global impact is important in the definition
  • Criteria for assessing the different techs
    • Effectiveness
    • Feasibility
    • Scalability
    • Sustainability (reversible? long term commitment?)
    • Enviro risks
    • Costs and affordability
    • Detection and attribution: can we measure consequences (intended or not) and attribute them to the tech?
    • Governance Challenges
    • Ethical issues
    • Social acceptability
    • Uncertainty on all of these criteria
  • Reference to Royal Society report 2009 for classification of methods
