Oceanographer Kristen Davis, an authority on ocean physics and climate sustainability, discusses the growing excitement around seaweed and kelp as tools to combat climate change. Like trees on land, these underwater plants use photosynthesis to absorb carbon dioxide and convert it into organic matter. When they die, some of that carbon may sink to the ocean depths. However, the science is still evolving and there’s a lot we don’t yet understand about how seaweed farming might impact carbon sequestration. Davis shares insights into the ongoing research and its promise on this episode of Stanford Engineering’s The Future of Everything podcast with host Russ Altman.Have a question for Russ?
