Solar radiation modification: NOAA State of the Science factsheet
WEB4 days ago · Highlights. 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. SRM is not considered a substitute for climate mitigation efforts, which include decarbonization and greenhouse gas emission cuts.
WEBProposed 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 …
Solar radiation modification - Wikipedia
WEBSolar radiation modification (SRM), also known as solar radiation management, or solar geoengineering, refers to a range of approaches to limit global warming by increasing the amount of sunlight (solar radiation) that the atmosphere reflects back to space or by reducing the trapping of outgoing thermal radiation.
