Thermal coupling of the Indo-Pacific warm pool and Southern Ocean over the past 30,000 years
The mechanism of the last deglacial global warming is key for future climate. Here, the authors shed light on the pivotal role of the thermal coupling between the western Pacific warm pool and the Southern Ocean. The role of the tropical Pacific Ocean and its linkages to the southern hemisphere duri...

Here we explore the evolution of Pacific horizontal and vertical thermal gradients over the past 30 kyr by compiling 340 sea surface and 7 subsurface temperature records, as well as one new ocean heat content record. Our records reveal that La Nina-like conditions dominated during the deglaciation as a result of the more intense warming in the western Pacific warm pool.
