How can soil carbon fight climate change?

Soil carbon sequestration has been hailed as a solution to the climate crisis. Can it really live up to the hype? Ellen Phiddian worked in science outreach before deciding to become, in her grandmother's words, "one of those whizz-bang science journalists". With a background in chemistry, she's particularly interested in renewable energy, catalysts, and deciphering the ingredients on food packages. Her favourite podcasts are Wardrobe Crisis,Friends at the Table, and just about any audiodrama. See omnystudio.com/listener for privacy information.
