 "past": {"account": "The past. The Cocos plate is almost all deep ocean, and no ice reached it in the last 30,000 years. At the ice age peak, about 20,000 years ago, the sea stood more than 120 metres lower, so Cocos Island, its only land, was about eight times its present size, and the sea surface was about 1.5 to 3 degrees colder than today. The water warmed slowly as the ice sheets melted, and the rising sea drowned most of the island’s shelf between about 16,000 and 10,000 years ago.", "source": "Méheust et al. 2018, arktos 4:1; Lhardy et al. 2021, Climate of the Past 17:1139; Orvis and Horn 2000, Quaternary Research 54:24; Lambeck et al. 2014, PNAS 111:15296; Lizano 2001, Revista de Biología Tropical 49 (Suppl. 2):163; Rincón-Martínez and Leduc 2012, PANGAEA; Benway et al. 2006, Paleoceanography 21"},
