Geoengineering schemes are being proposed with increasing urgency to mitigate present and future global warming. This session invites papers describing scientific and engineering studies related to climate modification through manipulation of solar energy input via processes internal or external to the atmosphere and other geo-engineering approaches. Also welcome are papers with new ideas or analysis of the history of geoengineering, and the policy, cost, ethical and political dimensions of global intervention. Examples of suggested schemes needing further investigation by the scientific community include the injection of reflective aerosols into the lower stratosphere, seeding marine clouds to modify their albedo, placement of mirrors in outer space to reflect incoming sunlight, ocean fertilization to enhance CO2 uptake and more. Proposed techniques may have regional or global scale engineering objectives. Presentations of well-developed designs for laboratory or field experiments are also acceptable.
