A 2,300-year-long annually resolved record of the South American
summer monsoon from the Peruvian Andes.
Proceedings of the National Academy of Sciences,
Vol. 108 (21), pp. 8583-8588, May 24, 2011.
doi:10.1073/pnas.1003719108
Decadal and centennial mean state changes in South American
summer monsoon (SASM) precipitation during the last 2,300 years
are detailed using an annually resolved authigenic calcite record
of precipitation d18O from a varved lake in the Central Peruvian
Andes. This unique sediment record shows that d18O peaked during
the Medieval Climate Anomaly (MCA) from A.D. 900 to 1100,
providing evidence that the SASM weakened considerably during
this period. Minimum d18O values occurred during the Little Ice
Age (LIA) between A.D. 1400 and 1820, reflecting a prolonged
intensification of the SASM that was regionally synchronous.
After the LIA, d18O increased rapidly, particularly during
the current warm period (CWP; A.D. 1900 to present), indicating
a return to reduced SASM precipitation that was more abrupt and
sustained than the onset of the MCA. Diminished SASM precipitation
during the MCA and CWP tracks reconstructed Northern Hemisphere
and North Atlantic warming and a northward displacement of
the Intertropical Convergence Zone (ITCZ) over the Atlantic,
and likely the Pacific. Intensified SASM precipitation during
the LIA follows reconstructed Northern Hemisphere and North
Atlantic cooling, El Niño-like warming in the Pacific,
and a southward displacement of the ITCZ over both oceans.
These results suggest that SASM mean state changes are sensitive
to ITCZ variability as mediated by Western Hemisphere tropical
sea surface temperatures, particularly in the Atlantic.
Continued Northern Hemisphere and North Atlantic warming
may therefore help perpetuate the recent reductions in SASM
precipitation that characterize the last 100 years,
which would negatively impact Andean water resources.
