abstract |
The responses of Asian monsoon subsystems to both hemispheric climate forcing and
external orbital forcing are currently issues of vigorous debate. The Indian summer
monsoon is the dominant monsoon subsystem in terms of energy flux, constituting one
of Earth’s most dynamic expressions of ocean–atmosphere interactions. Yet, the Indian
summer monsoon is grossly under-represented in Asian monsoon palaeoclimate records.
Here, we present high-resolution records of Indian summer monsoon- induced rainfall
and fluvial runoff recovered in a sediment core from the Bay of Bengal across Termination
II, 139–127 thousand years ago, including coupled measurements of the oxygen isotopic
composition and Mg/Ca, Mn/Ca, Nd/Ca and U/Ca ratios in surface-ocean-dwelling foraminifera.
Our data reveal a millennial-scale transient strengthening of the Asian monsoon that
punctuates Termination II associated with an oscillation of the bipolar seesaw. The
progression of deglacial warming across Termination II emerges first in the Southern
Hemisphere, then the tropics in tandem with Indian summer monsoon strengthening, and
finally the Northern Hemisphere. We therefore suggest that the Indian summer monsoon
was a conduit for conveying Southern Hemisphere latent heat northwards, thereby promoting
subsequent Northern Hemisphere deglaciation. |
