Researchers are exploring the potential of stratospheric aerosol injection to mitigate marine heatwaves, with some studies suggesting it could shield a significant portion of the oceans from heat waves. The concept, related to solar geoengineering, involves reflecting sunlight back to cool the earth. Its possible application to prevent extreme weather events, such as a Super El Niño, is being discussed, although the specifics and effectiveness of this approach are still being researched.
