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.
