A new study suggests that tiny organisms living underground may hoard most of the carbon in Swedish forest floors. That’s a good thing for the environment: If the carbon remains stashed in the soil, then it’s not escaping into the atmosphere. There, it could contribute to global warming.

And what’s happening in Sweden may be happening in forests elsewhere around the world.

These organisms, called mycorrhizal fungi, grow on tree roots. They provide trees with nutrients in exchange for the...
