Synopsis: A novel solution to climate change has been proposed by researchers: using dust from the moon to partially block incoming sunlight. 

UCLA News: Parson said the moon dust proposal was “fun, scientifically interesting speculation” that was unlikely to be put into practice, partially due to the larger cost and lack of control compared with Earth-based geoengineering options. “There seems to be a bit of uptick of interest in space-based geoengineering schemes more broadly,” Parson said. “They were long dismissed as wildly impractical due to technical and cost considerations, but my impression is that the ongoing reduction of launch costs is piquing people’s interest and strange ideas are bubbling around.”
