Biomass Burning 1991a). The burning of living and dead biomass is a very significant global source of atmospheric gases and particulates. Crutzen and colleagues were the first to assess biomass burning as a source of gases and particulates to the atmosphere (Crutzen et al., 1979; and Seiler and Crutzen, 1980). How

Wetlands, 1991), accounting for ~20% of the current global annual emission of ~450–550 Tg (10. g). Measurements of methane from Greenland and Antarctic ice cores indicate atmospheric concentrations of ~350 ppbv during the Last Glacial Maximum rising to 650 ppbv during the pre-industrial Holocene (Stauffer e

Sources and Sinks of Methaneasmussen, 1990). The current annual rate of increase of about 0.8% year. is attributed to increases in industrial and agricultural emissions since some key natural sources (e.g., wetlands and marshes) have been reduced due to development pressure, decreasing their area in various parts of the world
