Dr John Moore is a Research Professor at University of Lapland, Finland and Chief Scientist of GCESS at Beijing Normal University. His research focuses on geoengineering, sea level change, and ice sheet dynamics. In this episode, we take a deep dive into the cryosphere – the state and future of glaciers, sea ice and permafrost, as well as consider marine glacier geoengineering. John also shares his unique experience as a leader of a major geoengineering research program in China.
