North Atlantic late-Pleistocene climate (60,000 to 11,650 years ago) was characterized by abrupt and extreme millennial-duration oscillations known as Dansgaard-Oeschger (D-O) events. However, during the Last Glacial Maximum (LGM) 23,000 to 19,000 calendar years ago (23 to 19 ka), no D-O events are...
