11. Dr Fred Richards: the mantle, sea levels and roman fish tanks

Today we have Dr Fred Richards on the podcast. Dr Richards is a lecturer at Imperial studying how processes within the mantle affects Earth’s surface, including how the Earth's crust and upper mantle respond to the development and decay of icecaps. We discuss how icecaps have their own gravitational pull, how the sea level adjacent to melting icecaps actually falls, how the Earth's spin is slowing and causing our days to get longer, and so much more. Fred was awarded a Master's degree at Oxford and a PhD at Cambridge before becoming a research fellow at Harvard and then Imperial. He is now a lecturer at Imperial's Department of Earth Science and Engineering.
