The current stalemate on climate policy has brought the topic of climate engineering - or geoengineering - onto the research agenda as a potential option alongside mitigation and adaptation. A number of climate engineering techniques have been proposed as tools to ameliorate some of the effects of climate change. Most of the proposed radiation management techniques would involve increasing the amount of solar radiation reflected by the Earth through, for example injection of particles in the stratosphere, brightening of low clouds over the oceans or brightening of the land surface. The thinning of cirrus clouds is an exception, which aims to cool the climate by releasing more thermal radiation to space.

This session will present new findings from studies involving Stratospheric Aerosol Injections, Marine Sky Brightening and Cirrus Cloud Thinning. Contributions from the Geoengineering Intercomparison Project (GeoMIP) and other climate model and impact studies are welcome.

Invited speakers:
Prof. Ken Caldeira, Carnegie Institution Department of Global Ecology at Stanford University.
Prof. Hannele Korhonen, Finnish Meteorological Institute.
