Solar geoengineering

In News
  • The United States is eyeing a controversial tool to counter global warming: Solar radiation management (SRM), which involves reflecting a small fraction of sunlight into space.
About SRM
  • SRM involves reflecting a small fraction of sunlight back into space as a means to counteract global warming.
  • The proposed research governance framework aims to provide guidance on transparency, engagement, and risk management for publicly funded solar geoengineering research.
  • This framework will contribute to informed decision-making and responsible practices in this emerging field. 
  • The scientific dimensions of SRM involve new and continued ground-based, airborne, and space-based observations and improving global modelling of SRM approaches and scenarios.
  • They can help in the understanding of the physical processes and outcomes associated with SRM.
  • In addition, cultural, moral, and ethical considerations are essential but often overlooked in model-based evaluations.
  • The report highlights several potential risks of SRM, such as changes in precipitation patterns, stratospheric temperatures, ozone amounts, sea-level rise, ocean acidification, productivity, terrestrial vegetation, coral reefs, biodiversity, crop production, and ecosystems. 
Risks involved
  • The report highlighted gaps and potential risks with SRM.
  • These include potential changes in precipitation patterns, changes in stratospheric temperatures, ozone amounts, sea-level rise, ocean acidification, productivity and mixing, terrestrial vegetation, coral reefs, biodiversity, crop production and ecosystems.
