Model shows downside of geo-engineering clouds

Efforts to offset some of the effects of climate change get futuristic with “geo-engineering” techniques — trying to actually alter how Earth’s systems operate. One of those ideas, marine cloud brightening, is the focus of new research published in the journal Nature Climate Change. Host Carolyn Beeler talks with one of the co-authors, climate scientist Kate Ricke at the Scripps Institute of Oceanography and School of Global Policy and Strategy at UC San Diego.
