Solar Radiation Modification
Solar Radiation Modification (SRM), also known as Solar Radiation Management, Radiation Modification Measures or Solar Geoengineering, would aim to address a symptom of climate change by reflecting more sunlight back into space, or by allowing more infrared radiation from Earth to escape, in order to reduce the Earth’s temperature. It includes numerous proposed methods which differ significantly. None are ready for deployment. Solar Radiation Modification could not be a substitute for reducing emissions, or removing atmospheric CO2.

To Geoengineer Or Not To Geoengineer…
Created by the Red Cross Red Crescent Climate Centre in collaboration with C2G, this animation focuses on the big questions around stratospheric aerosol injection, referencing global cultural icons.
Icons
In the interest of promoting global discussion about the need for governance of Solar Radiation Modification, C2G developed a set of icons representing these approaches, available to all to use freely.
The icons are available in png and svg file formats.
