Thus, the relationship between the Asian monsoon and the North Atlantic observed during the glacial period appears to continue into the early Holocene.In addition, three of the four events correlate within error with outburst events from Lake Agassiz.Today’s fossil fuel use drives a global climate experiment: how much will global temperatures rise as a result of carbon emissions?To answer this question, scientists need to understand processes that cause global temperatures to vary in the absence of emissions.

Compared to paleoclimate proxies from sedimentary archives, the age uncertainty is unusually small, around /−100 years for the last 21 000-year interval.O events centered at 11225±97 yr BP (1.05‰), 10880±117 yr BP (1.15‰), 9165±75 yr BP (1.4‰), and a double event centered at 8260±64 yr BP (1.1‰) and 8080±74 yr BP (1.0‰) punctuated this period of high monsoon intensity.All four events correlate within error with climate changes in Greenland ice cores.O record characterizes orbital- to decadal-scale variability of Asian summer monsoon (ASM) intensity, with the Holocene optimum period (HOP) between 9.8 and 6.8 ka BP which is reinforced by its co-varying δO indicates its high sensitivity to climate change.Four centennial-scale weak ASM events during the early Holocene are centered at 11.2, 10.8, 9.1 and 8.2 ka.
