Glacier extent during the Younger Dryas and 8.2-ka event on Baffin Island, Arctic Canada
Greenland ice cores reveal that mean annual temperatures during the Younger Dryas (YD) cold interval—about 12.9 to 11.7 thousand years ago (ka)—and the ~150-year-long cold reversal that occurred 8.2 thousand years ago were ~15° and 3° to 4°C colder than today, respectively. Reconstructing ice-sheet...
