Christmas Lectures 2020: Engine Earth - with Chris Jackson

In the first lecture of the 2020 Christmas Lectures, geologist Chris Jackson shows us how the planet’s oldest rocks and fossils tell a story of radical climate changes throughout history and how the Earth’s finely balanced tectonic system – volcanoes – has controlled the level of carbon dioxide in the air.

Prof Chris Jackson is a geologist and adventurer, who is currently Chair in Sustainable Geoscience at the University of Manchester. His academic position has not limited his opportunities for further travel and adventure, with his geological fieldwork taking him to remote, and physically and mentally challenging locations, including the Argentinian Andes, the Borneo rainforest and the Sinai Desert in Egypt. https://www.rigb.org/christmas-lectur... This Christmas Lecture was originally broadcast on BBC4 on 28 December 2020.
