Experts believe that reducing emissions alone will not be sufficient in addressing the climate crisis, highlighting the need for additional measures like cloud brightening or reflecting sunlight back into space.
Cloud brightening involves spraying sea salt into clouds to reflect sunlight and cool the Earth, part of solar geoengineering. Studies on cloud brightening face controversy, with some mistaking research for experiments.
Research on particles' movement for cloud brightening models was wrongly perceived as a cloud brightening study, emphasizing the importance of understanding pollution effects beyond just climate solutions.
