Modern limnological data show that Pumacocha d18Ocal reflects the average annual isotopic composition of the lake's surface waters (d18Olw), and that d18Olw tracks the isotopic composition of precipitation (d18Oprecip), which is largely controlled by the intensity of the South American summer monsoon (SASM). Based on these relationships we use down-core d18Ocal measurements as a proxy for d18Oprecip that varies with the intensity of SASM precipitation. Pumacocha d18Ocal increased rapidly between 11,200 and 10,300 yr B.P. from -14.5‰ to -10.5‰, reaching a maximum of -10.3‰ by 9800 yr B.P. After 9800 yr B.P., d18Ocal underwent a long-term decrease that tracked increasing Southern Hemisphere summer insolation, suggesting that enhanced SASM precipitation was linked to precessional forcing. Higher-frequency trends did not follow insolation and therefore represent other variability in the climate system. Millennial-scale trends from Pumacocha strongly resemble those from lower-resolution tropical Andean ice and lake core isotopic records, particularly the Huascaran ice core, and low elevation speleothems. These relationships suggest that tropical Andean isotopic records reflect variations in precipitation intensity related to precessional forcing rather than tropical temperatures. They also demonstrate a coherent pattern of SASM variability, although with differences between low elevation and Andean records during the late Glacial to Holocene transition and the late Holocene. Centennial and decadal SASM precipitation variability is also apparent. Reduced SASM rainfall occurred from 10,000-9200, 7000-5000, 1500-900 yr B.P. and during the last 100 years. Intensifications of the SASM occurred at 5000, 2200-1500, and 550-130 yr B.P. with the amplitude of variability increasing after 2200 yr B.P. These periods may represent SASM responses to ocean-atmosphere variability related to orbital and radiative forcing (e.g., El Niño-Southern Oscillation and the Intertropical Convergence Zone).
