|a 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 response to these climate perturbations can help
evaluate ice-sheet sensitivity to climate change. Here, we report the widespread advance of
Laurentide Ice Sheet outlet glaciers and independent mountain glaciers on Baffin Island,
Arctic Canada, in response to the 8.2-ka event and show that mountain glaciers during the
8.2-ka event were larger than their YD predecessors. In contrast to the wintertime bias of
YD cooling, we suggest that cooling during the 8.2-ka event was more evenly distributed
across the seasons. |
