Marine cloud brightening, a geoengineering technique, may have the potential to cool the earth, but it could also impact the stratospheric ozone layer. The effects of this technique on atmospheric chemistry and radiative forcing are being studied, with some research suggesting that injecting particles into the stratosphere could also make marine clouds brighter. The relationship between marine cloud brightening and stratospheric ozone is still being explored, with various studies and factsheets examining the implications of this technique.
