Geoengineering technologies, such as stratospheric aerosol injection (SAI), could reverse the warming effects of climate change by seeding the stratosphere with reflective particles, similar to volcanic eruptions. SAI could limit temperature increases, reduce risks, and allow more time to transition from fossil fuels, at an estimated cost of $10 billion yearly.
However, SAI presents challenges. It must be coupled with greenhouse gas emission reductions to address issues like ocean acidification, as it doesn't remove greenhouse gases. Geopolitically, SAI could alter weather patterns, benefiting some regions at the expense of others, potentially causing international opposition. Some nations might reduce their commitment to carbon dioxide reductions, relying instead on SAI's benefits. Furthermore, global norms and standards are lacking to guide SAI deployment.
