Abstract: A sea change in climate A critical question regarding millennial-scale climate variability during the last glacial–interglacial transition is whether the ocean or the atmosphere triggered abrupt climate changes. Specifically, either reorganization of the ocean's thermohaline circulation, or changes in tropical atmosphere–ocean dynamics similar to the present-day El Niño Southern Oscillation pattern could be involved. A high-resolution reconstruction of sea-surface temperatures in the equatorial Pacific over the past 30,000 years points to the oceans as the trigger for change, at least during the events known as Heinrich event 1 and the Younger Dryas.
