A Low-Latitude Framework for Climate Variability Over the Last 60,000 Years

Caption

A new high-resolution and precisely dated Asian composite cave record covers past 60,000 years. 
The record's precise chronology provides benchmarks for calibrating and correlating global climate variability. 
The monsoon dynamics were coupled with the Atlantic Meridional Overturning Circulation instead of ice volume. 
The most prominent millennial cycle is ~4.5-ka, close to precession cycles, implying an external forcing. 
Multidecadal-centennial climate variations in periodicity and amplitude changed from glacial to interglacial.
