To get a more funded and sound opinion on how risky SRM (Solar Radiation Management) and SAI (Stratospheric Aerosol Injection) are I would suggest that we read and study a lot. I have been researching on this issue since at least 4 years. I have also done interwiews with many metereologists and IPCC experts. I am studying the issue of environmental (air) pollution since 1986. And still researching, I am absolutely aware of how much we still don’t understand about climate, weather and air pollution. So we have to be patient and not to go in search for rapid technological fixes to solve the climate disruption. Here a list of 31 arguments against the deployment of Solar Radiation Management or Stratospheric Aerosol injection based on the studies and research of a.o. Alan Robock a distinguished metereologist at a global level
- Drought in Africa and Asia
- Perturb ecology with more diffuse radiation
- Environmental impact of implementation
- Effects on plants of changing the amount of solar radiation and partitioning between direct and diffuse
- Continued ocean acidification
- Ozone depletion with more UV at surface
- Affect stargazing
- More sunburn from diffuse radiation
- Regional climate change, including temperature and precipitation
- Whitening of the skies
- Unknowns about Climate system response
- Less solar radiation energy generation by solar power, especially for those requiring direct radiation
- Rapid warming if stopped
- Cannot stop effects quickly
- Human errors
- Unexpected consequences
- Commercial control
- Military use of technology
- Conflicts with current treaties (weaponizing the weather?)
- Whose hand on the thermostat?
- Degrade terrestrial optical astronomy
- Affect satellite remote sensing
- Societal disruption
- Conflict between countries
- Effects on airplanes flying in the stratosphere
- Effects on electrical properties of the atmosphere
- Impacts on troposphere chemistry
- Effects on cirrus clouds as aerosols fall into the troposphere
- Environmental impacts of aerosol injection, including producing and delivering aerosols
- Moral hazard – the prospect of it working would reduce drive for cutting emissions
- Moral authority: do we have the right to do this?
