This chapter describes the conditions that lead to biogenic methane formation in natural environments, the metabolic pathways and interactions that lead to methanogenesis, and the implications of these

Most of the methane is removed by reacting with tropospheric OH radicals; lesser amounts are removed by soils and stratospheric oxidation by OH, O(.D), and minor reactions. This chapter is on the removal rate of CH. and its variability in space and time.
