A technofix for the climate? Atmospheric geoengineering (Solar Radiation Management)



Large-scale technological interventions to “fix” the climate crisis are moving up on the political agenda. Some climate scientists are now proposing geoengineering interventions in the atmosphere to suppress global warming – most prominently SAI (Stratospheric Aerosol Injection): The idea here is to inject inorganic particles – such as sulphur dioxide – into the stratosphere to block incoming sunlight.

In other schemes, plastic beads and other materials are proposed to cover ice surfaces to prevent them from melting. These schemes to manipulate our ecosystems come with great risks and uncertainties, as well as with foreseeable adverse impacts on our natural ecosystems and human communities depending on them.

Part III of “A technofix for the climate?” presents SAI as a method of Solar Radiation Management and focusses on the risks, negative impacts and potential side-effects of this “solution” for tackling climate change. These include severe implications for international peace and security.

For more background information and analysis on geoengineering, and to get involved, please visit a civil society information hub on geoengineering, run by ETC Group, Biofuelwatch and Heinrich Böll Foundation, and our website

Part I & Part II present geoengineering and their risks in other parts of our biosphere:
