The ice age sea, more than 120 metres lower, never came near its floor, and no ice ever reached it. What changed was the water above it: at the ice age peak the surface was about 1.5 to 4 °C colder than today, and it warmed back mostly between about 17,000 and 7,000 years ago.", "source": "Lambeck et al. 2014, PNAS 111:15296; Lhardy et al. 2021, Climate of the Past 17:1139; Méheust et al. 2018, arktos 4:1; Tierney et al. 2020, Nature 584:569; Osman et al. 2021, Nature 599:239"},
