Here, we present four absolutely dated, overlapping stalagmite oxygen isotopic records from northern Borneo that span most of the last glacial cycle. The records suggest that northern Borneo's hydroclimate shifted in phase with precessional forcing but was only weakly affected by glacial-interglacial changes in global climate boundary conditions. Regional convection likely decreased during Heinrich events, but other Northern Hemisphere abrupt climate change events are notably absent. The new records suggest that the deep tropical Pacific hydroclimate variability may have played an important role in shaping the global response to the largest abrupt climate change events. STUDY NOTES: Oxygen stable isotope records (d18O) from four stalagmites collected in three different caves in Gunung Mulu National Park, Northern Borneo, Malaysia (4º06'N, 114º50'E). Chronologies were established by 238U-234U-230Th dating. Stalagmite SC02 and SC03 were collected from Secret Cave in Gunung Mulu, BA02 from Bukit Assam in Gunung Buda, and SCH02 from Snail Shell Cave in Gunung Buda.
