Summary
Abstract: This data set consists of faunal abundance data from Arabian Sea Box
Cores.

[ABSTRACT]

Climate reconstructions reveal unprecedented warming in the last
century, however little is known about trends in aspects such as the
monsoon. We reconstructed the monsoon winds for the last 1,000 years
using fossil Globigerina bulloides abundance in box cores from the
Arabian Sea, and found that monsoon wind strength increased during the
past 4 centuries, as the northern hemisphere warmed. We infer that
the observed link between Eurasian warmth/snow cover and the SW
monsoon persists on the centennial scale. Alternately, the forcing
implicated in the warming trend (volcanic aerosols, solar output,
greenhouse gases) may directly affect the monsoon. Either
interpretation is consistent with the hypothesis that the SW monsoon
strength will increase during the coming century as greenhouse gas
concentrations continue to rise and northern latitudes continue to
warm.
