It's been a huge few episodes for stories about our ever-changing Earth system, from living glaciers and volcanic eruptions to our human moments in a warming world. Holly & Anthony take this time to actually understand and reflect on recent conversations with geochemist-volcanologist Dr Lucy McGee and glaciologist Hedda Andersen, sprinkled with some ideas about the growth of Antarctica's ice sheets (see How Antarctica Got its Ice⁠ and Antarctic Ice Sheet variability Across the Eocene-Oligocene Boundary Climate Transition⁠), plus some climate change 101 thanks to the IPCC Sixth Assessment Report⁠ and ⁠Special Report on the Ocean and Cryosphere in a Changing Climate.
