GC31H:
Evaluating the Feasibility and Consequences of Solar Geoengineering Posters


Submit an Abstract to this Session


Session ID#: 45737

Session Description:
Solar geoengineering is a term that describes a set of proposals to directly alter the Earth’s radiation balance to reduce the risks of climate change. Understanding whether and how solar geoengineering could play a role alongside emissions reductions, carbon removal and adaptation as a response to climate change poses serious scientific challenges. This session will present work that addresses three of these challenges:

Can a substantial negative radiative forcing (e.g., 1-4 Wm-2) be practically achieved?

What is the climate response to radiative forcing from solar geoengineering?

What are the non-climate environmental risks or impacts of specific methods of solar geoengineering?

Research on comparative risk assessments is particularly encouraged, i.e. how do the risks of solar geoengineering compare to the risks without solar geoengineering?

The oral session will conclude with a 30 minute panel discussion. In this discussion we will reverse the usual format and invite the audience to answer questions posed by the speakers.

SRM means more than global geoengineering.The Mie theory behind stratrospheric aerosol brightening can also make water more reflective. Since most agricutural water reservois are small, short-lived dispersions of reflective microbubbles (hydrosols) could help solve a global paradox of conservation economics -that water is too cheap to conserve.
