How Did Monsoon Affect Methane?
qOrbital procession affects solar
radiation at low latitudes
è solar
radiation affects the strength of low-latitude monsoons
è monsoon
fluctuations changes the precipitation amounts in Southeast Asia
è heavy
rainfalls increase the amount of standing water in bogs
è decaying
vegetation used up any oxygen in the water and creates the oxygen-free conditions needed to
generate methane
è the
extent of these boggy area must have expanded during wet monsoon maxima and shrunk during dry
