Peat. Climate and Fires

Peat, or turf, is an accumulation of partially decayed vegetation matter. Peat forms in wetland bogs, moors, and peat swamp forests. Peat is harvested as an important source of fuel in certain parts of the world. Peat has a high carbon content and can burn under low moisture conditions. Once ignited by the presence of a heat source, it smolders. These smoldering fires can burn undetected for very long periods of time (months, years and even centuries) propagating in a creeping fashion through the underground peat layer. The rate of global warming could lead to a rapid release of carbon from these peat lands that would then further accelerate global warming. Two recent studies published by the Mathematics Research Institute at the University of Exeter highlight the risk that this 'compost bomb' instability could pose, and calculate the conditions under which it could occur.
