Researchers have found that injecting stratospheric aerosols at low altitudes and high latitudes may be feasible using existing aircraft, which could potentially be used to cool the planet. However, some studies also highlight the potential risks and unpredictability of this geoengineering technique, raising concerns about its practical limitations and potential consequences. The effectiveness and safety of stratospheric aerosol injection as a means to combat global warming remains a topic of ongoing research and debate.
