Atmospheric convection over the west Pacific warm pool — an area of warm water in the western tropical Pacific Ocean — is a major source of heat and moisture to extra-tropical regions, so this process may have played an important role in global climate change in the past. This role remained uncertain, because of a lack of well dated, high-resolution climate records from this region. Now we have the missing data, in the form of an oxygen isotope record from three cave stalagmites from northern Borneo, reflecting changes in tropical Pacific hydrology on millennial timescales over the past 27,000 years. The records indicate that the tropical Pacific hydrological cycle is sensitive to high-latitude climate processes in both the Northern and Southern Hemispheres, as well as to external radiative forcing, and that it may have played an important role in abrupt climate change events.
