Abstract
Understanding processes controlling the atmospheric methane
(CH4) mixing ratio is crucial to predict and mitigate future climate
changes in this gas. Despite recent detailed studies of the last ∼ 1000
to 2000 years, the mechanisms that control atmospheric CH4 still remain
unclear, partly because the late Holocene CH4 budget may be comprised of
both natural and anthropogenic emissions. In contrast, the early Holocene was
a period when human influence was substantially smaller, allowing us to
elucidate more clearly the natural controls under interglacial conditions
more clearly. Here we present new high-resolution CH4 records from Siple
Dome, Antarctica, covering from 11.6 to 7.7 thousands of years before
1950 AD (ka). We observe four local CH4 minima on a roughly 1000-year
spacing, which correspond to cool periods in Greenland. We hypothesize that
the cooling in Greenland forced the Intertropical Convergence Zone (ITCZ) to
migrate southward, reducing rainfall in northern tropical wetlands. The
inter-polar difference (IPD) of CH4 shows a gradual increase from the
onset of the Holocene to ∼ 9.5 ka, which implies growth of boreal
source strength following the climate warming in the northern extratropics
during that period.
