Greatest concentrations of world's soil carbon pinpointed in peat bogs

The greatest concentrations of the world's soil carbon have been pinpointed by researchers – and much of it is a dangerously flammable addition to climate change concerns. An international scientific survey of peat bogs has calculated that they contain more carbon than all the world's forests, heaths and grasslands together – and perhaps as much as the planet's atmosphere. Since peat can smoulder underground for years, it is another potential factor in global warming calculations.
