Integrated Assessment of Geoengineering Proposals (IAGP)

"Integrated Assessment of Geoengineering Proposals (IAGP) is a four year research project, (October 2010 to September 2014) and is funded by the Engineering and Physical Sciences Research Council (EPSRC) and the Natural Environment Research Council (NERC).  IAGP brings together a broad range of expertise, from climate modelling to philosophy and engineering to public perceptions to conduct an objective, policy-relevant assessment of geoengineering proposals."

Cao, Long; et al. (2012): Climate response to changes in atmospheric carbon dioxide and solar irradiance on the time scale of days to weeks

Cao, Long; Bala, Govindasamy; Caldeira, Ken (2012): Climate response to changes in atmospheric carbon dioxide and solar irradiance on the time scale of days to weeks. In: Environ. Res. Lett 7 (3), pp. 34015. DOI 10.1088/1748-9326/7/3/034015

"In this study, we investigate climate response on the time scale of days to weeks to a step-function quadrupling of atmospheric CO2 and contrast this with the response to a 4% increase in solar irradiance."
