newsbits mindmap notes


The US is considering SRM, a controversial tool, to counter climate change.


  • It is also known as solar geoengineering.
  • These are technologies that could counteract the rising global temperatures by reflecting sunlight away from the earth.


  • Potential changes in precipitation patterns
  • Alterations in stratospheric temperatures
  • Changes in ozone concentration
  • Not addressing key factors like GHG concentration, ocean acidification, etc.


  • Stratospheric injection aerosols
  • Brightening of marine clouds to increase their reflectivity
  • Surface albedo enhancement   
  • Decreasing the amount of high altitude cirrus clouds (cloud thinning)
  • Space based methods like mirrors in space
