Burying burnt trees after a wildfire could help the climate

A 3,700-year-old buried log still holding the carbon it had pulled from the air sparked a radical idea: bury dead trees before they release their stored CO2. Guest host Johanna Wagstaffe wades into the wonder with the scientist who made the ancient find – in Canada. Then, we hear from a company aiming to bury trees in a sort of carbon bunker, creating carbon credits to pay for reforestation. And we check in with a forest ecologist who explains why it’s not one-size-fits-all when it comes to managing forests that have burned.
