In the US alone there are several regions where the peat depth runs from 6 to 60 or more feet (2-20 meters). A few were extensively mapped by states a century ago. So long as it stays wet, its quite stable, and plants (e.g. mosses) consume much of the gases released. From an article about the huge deposit recently noticed in the Congo: "Pound for pound, peat is an incredibly carbon-rich soil. Over thousands of years, peatlands can build up into deposits tens of feet thick. Peatlands cover just 3 percent of the earth, but stockpile twice as much carbon as all of the world’s trees and one-fifth of all the carbon stored in soils. If just a third of this peatland burned, the amount of CO2 in the air would double." [0] [1 Congo] More info about peat fires in NA.
