Peatlands cover only a small part of the planet, but they store huge amounts of carbon and hold thousands of years of environmental and human history. In this episode of Peatpod, Dr Lorna Harris chats with Professor Julie Loisel about how scientists take peat cores and use them to reconstruct past climates, measure carbon, and track how ecosystems change over time. The conversation travels across the Americas, from Alaska and Canada to Costa Rica, Peru, and the Caribbean, and on to Antarctica.
