My guest today is Dr. Ella Holme, a postdoc at Yale University. Dr. Holme talks about her research on the mineral olivine as a potential antidote for climate change. Olivine can remove carbon dioxide from air and water, and further research into this mineral can help counteract increasing CO2 emissions. We also talk about how olivine is like the Hulk, and how Dr. Holme's path into geology started from childhood fears of tsunamis, climate change, and... werewolves.
