modified by effects of air temperature and humidity. Systematic errors in the RCM are
identified by comparing its simulation of present-day climate with observations. After correcting
such biases, changes in summer mortality rates in the 21st century are projected using the
GAM developed with the air temperature and humidity predicted by the RCM.

<strong>The</strong> climate of Marine Isotope Stage 3 (MIS 3) was extremely variable on a millennial
timescale, characterized by Dansgaard–Oeschger (DO) events and Heinrich (H) events. In this
work, sediments from the upper part of Core 17954-2, located at the upwelling area off the
Vietnam coast in the western SCS, was analyzed to uncover how the rapid climate changes in
this region responded to that in high-latitude region of the Northern Hemisphere during MIS 3,
by discussing the changes of surface sea temperature (SST), depth of thermocline (DOT) and
primary productivity with AMS14C dating and stable oxygen isotope analysis on the basis of
analysis of planktonic foraminifera species.<strong>The</strong> records of planktonic foraminifera in Core
17954-2 responded to rapid climate events in the records of GISP2. Besides, there were more
changes similar to these observed in this work.. In certain of IS events, the conditions of low
SST, shallow DOT and high productivity implied upwelling taking place when it was warm. It
was estimated that East Asian Monsoon enhanced during these warm events. On the other
hand, three stages showed in some indexes also supported a concept that enhanced East
Asian summer monsoon could influence this region.
