Solar Radiation Modification: NOAA State of the Science Factsheet

Excerpt:  “Solar Radiation Modification (SRM) refers to deliberate, large-scale actions intended to decrease global average surface temperatures by increasing the reflection of sunlight away from the Earth. Proposed SRM methods involve the use of aerosols (small particles) or other materials to increase the reflectivity of the atmosphere, clouds, or Earth’s surface. These methods have the potential to lower surface temperatures more quickly than carbon dioxide removal (CDR) methods and reduce some risks posed by climate change, while posing other risks still to be understood.”
