"Exploring Brighter Clouds as a Climate Change Solution"

Scientists are considering the possibility of using a geoengineering technique called "marine cloud brightening" (MCB) to combat climate change by making clouds over the oceans thicker and brighter. This would involve a fleet of ships spraying seawater into the clouds to cool the atmosphere underneath. While the idea has been around for 30 years, a new study published in Science Advances lays out the viability of this technique and proposes a research program. However, challenges and potential side effects, such as changes in weather patterns, need to be addressed before considering widespread deployment.
