Effect of stratospheric aerosol injection on marine heatwave events off the coast of South Africa.

ABSTRACT: How to mitigate the negative effects of global warming is one of the most challenging issues of our time. Stratospheric Aerosol Intervention (SAI) may help reduce these effects, but its impact on extreme sea surface temperature events like marine heatwaves (MHWs) remains uncertain, particularly in productive areas such as the Agulhas Bank (AB) in the southern coast of South Africa. This study investigates to what extent the SAI can mitigate the impacts of global warming on MHW metrics (frequency, duration, intensity, and cumulative intensity) in the AB. We used ARISE-SAI-1.5 simulations, aimed to limit the future global mean surface temperature to 1.5 °C above pre-industrial levels, to calculate the MHW metrics and compare them to those of the SSP2-4.5 simulations under global warming.
