A popular climate fix could accidentally trigger massive changes to global weather

The study reveals that some geoengineering strategies could inadvertently cause significant shifts in global weather. Specifically, enhancing marine clouds in the eastern Pacific might severely disrupt the El Niño cycle, leading to widespread changes in climate patterns worldwide. In contrast, stratospheric aerosol injection appeared to have little impact on the system. This research underscores the importance of fully understanding Earth's climate mechanisms before implementing any climate intervention strategies to avoid unintended and potentially catastrophic consequences.
