The release of carbon from decomposing Arctic soils, following permafrost thaw, is a potentially important climate feedback. Research now shows how shrub cover protects permafrost carbon reservoirs. Manipulative experiments show that the loss of shrub cover leads to a transition of the tundra to waterlogged methane-emitting conditions.
