Scientists are studying the Last Interglacial period—a warm phase between ice ages roughly 125,000 years ago—to understand how ice sheets retreated and sea levels rose when global temperatures climbed. New climate models and paleoclimate evidence reveal how ocean heat transport and competing ice dynamics shaped coastlines during that epoch, offering insights into future warming scenarios.
·Ross Ice Shelf and West Antarctic Ice Sheet were significantly diminished during Last Interglacial warming
·Greenland ice sheet experienced substantial retreat and regrowth cycles during the warm period
·Southern Ocean heat transport played a key role in amplifying interglacial warming patterns
·Reef growth episodes were driven by competing effects of polar ice sheets on sea level changes
·Glacial–interglacial and millennial climate signals have distinct origins traceable in atmospheric dust records
