M07 Earth System Response to Solar Radiation Modification: Modeling, Impacts and Uncertainties

Convener(s): Govindasamy Bala (India), Hauke Schmidt (Germany)

Description
To achieve temperature stabilization goals set by the Paris Agreement requires substantial reduction in greenhouse emissions and even net negative CO2 emissions, which is a grand challenge for the human society. Solar radiation modification (SRM), a class of climate intervention options that aims to cool the Earth by deflecting some more sunlight back to space, has attracted growing interest. Enhancement of the burden of reflective aerosols in the stratosphere, increasing the reflectivity of marine clouds by injecting cloud condensation nuclei and painting the urban roofs white are some examples. SRM research is still at an early stage, in particular with regard to efficiency, impacts and uncertainties of the different proposals. This session welcomes contributions to all aspects of SRM research, including modeling study of climate and Earth system response to various forms of SRM, benefits and side effects of different SRM approaches from local to global scales, and uncertainties underlying climate processes, geophysical response and ecosystem and societal impact of SRM. We also welcome studies on the engineering aspects of different SRM schemes and international governance of SRM.
