Deep dives
Understanding Solar Radiation Modification
Solar radiation modification (SRM) is a geoengineering concept aimed at cooling the planet by blocking sunlight, primarily through methods such as spraying sulfates into the stratosphere. This idea draws inspiration from the natural cooling effects observed after significant volcanic eruptions, which inject large amounts of sulfate particles into the atmosphere. Researchers began to revisit this concept in the late 1990s after some studies indicated its potential effectiveness. Although controversial and under debate, SRM has recently garnered increased interest from philanthropies and technology sectors as governments struggle to combat climate change.
