A Natural Experiment in the Sky: Shipping, Clouds, and Climate

Shipping pollution changed clouds. What can scientists learn? What happens when cleaner shipping fuel suddenly changes the atmosphere above the ocean? In this episode of Oceanography, meteorologist Dr. Michael Diamond explains how shipping pollution, cloud formation, and climate are connected, and how a major fuel regulation and disrupted global shipping routes created a rare natural experiment for scientists. The conversation explores aerosols, sulfur pollution, cloud brightening, and what these real-world changes can teach us about marine climate intervention, including marine cloud brightening and solar geoengineering. If you want to understand how human activity is already shaping clouds, warming, and climate policy, this episode offers a grounded, fascinating look at one of the most complex questions in climate science.Support our science communication directly by donating to Pine Forest Media or directly on PayPalEpisode Guests: Dr. Michael DiamondFind Dr. Diamond’s published article on the impacts of the IOM regulation and preprint on the impacts of a changed shipping route. Review Dr. Diamond’s publications on Google ScholarListen to Pine Forest Media’s NEWEST PODCAST GREEN FREQUENCYEpisode Transcript  and more information on the Pine Forest Media websiteFollow Pine Forest Media on Instagram @pineforestmediaHosted, produced, and edited by Clark Marchese Cover art by Jomiro EmingTheme music by Nela RuizFind some more Pine Forest Media podcasts belowListen to Plastic Podcast on Spotify or Apple PodcastsListen to South Pole on Spotify or Apple PodcastsListen to Something in the Water on Spotify or Apple Podcasts Hosted on Acast.
