The IPCC will address the physical science basis of geoengineering in several chapters of the WGI contribution to AR5. WGII will address the impacts of geoengineering proposals on human and natural systems, and WGIII needs to take into account the possible impacts and side effects and their implications for mitigation cost to define the role of geoengineering within the portfolio of response options to anthropogenic climate change, including an evaluation of options for appropriate governance mechanisms.
