Researchers are exploring the use of stratospheric aerosol geoengineering as a potential method to mitigate carbon loss from arctic permafrost. However, the approach is not without its challenges, with concerns raised about engineering and logistical limitations, as well as potential risks and uncertainties. The effectiveness of stratospheric aerosol injection in preserving arctic permafrost is being studied, with some simulations suggesting that natural variability can mask the response to such interventions.
