Monsoon and Methane
q On the 23,000-year cycle,
methane variations closely
resemble the variations of
monsoon strength.
q The peak values of methane
match the expected peaks in
monsoon intensity not only in
timing but also in amplitude.
q This match suggests a close
connection between CH4
concentrations and the
monsoon on the 23,000-year
climate cycle.
q By why?
