Can Stratospheric Aerosol Injection Save the Amazon Rainforest?

New research from the University of Exeter explores whether stratospheric aerosol injection (SAI) can protect the Amazon rainforest from climate driven carbon loss. By mimicking the cooling effect of volcanic eruptions, SAI could potentially keep the rainforest productive and prevent large scale dieback even under high CO2 levels. While the models show a potential 10.8% increase in land carbon storage compared to high emission scenarios, the technique carries significant risks. These include disrupted rainfall patterns, potential impacts on agriculture, and the danger of a rapid temperature spike if the system were to suddenly fail.

The model shows SAI helps carbon storage, but it does nothing for the actual CO2 concentration. We are talking about masking a symptom while the underlying chemistry of the atmosphere continues to degrade. The policy risk here is that this becomes an excuse to slow down decarbonization.

Agreed. I am more interested in the termination effect mentioned. If we rely on a technical fix to keep the Amazon stable and the system crashes, the resulting temperature spike would be a nightmare for any existing infrastructure or grid stability in those regions.

Study basically says SAI could be an emergency brake for the Amazon. It keeps the forest from hitting a tipping point by lowering the heat, even if it messes with rainfall. Worth reading if you want to see how desperate the climate modeling is getting.
