Models and palaeoclimate data suggest that the tropical Pacific
climate system plays a key part in the mechanisms underlying
orbital-scale and abrupt climate change1­7
. Atmospheric convec-
tion over the western tropical Pacific is a major source of heat and
moisture to extratropical regions, and may therefore influence
the global climate response to a variety of forcing factors. The
response of tropical Pacific convection to changes in global
climate boundary conditions, abrupt climate changes and radi-
ative forcing remains uncertain, however. Here we present three
absolutely dated oxygen isotope records from stalagmites in
northern Borneo that reflect changes in west Pacific warm pool
