Frozen ground is not just cold dirt; in Arctic landscapes, it can be a deep storage vault for ancient carbon and a plug that limits underground water movement. This episode follows a modeling study that asks what happens when that plug thaws and groundwater starts moving again. The answer matters for rivers, lakes, coastal waters, and climate: some carbon may be turned into greenhouse gases underground, while some may travel with groundwater into streams long before all the permafrost disappears. Hosts unpack the idea of a virtual experiment, why old carbon buried several meters down is hard to measure, and what field data scientists still need to make better forecasts for a warming Arctic.
