About 120kya Northwest Greenland was 8C warmer than today and lost about 400km (about 20%) of its thickness. "In a 2013 study published in Nature, 133 researchers analyzed a Greenland ice core from the Eemian interglacial. They concluded that during this geological period, roughly 130,000–115,000 years ago, the GIS (Greenland Ice Sheet) was 8 degrees C warmer than today. This resulted in a thickness decrease of the northwest Greenland ice sheet by 400 ± 250 metres, reaching surface elevations 122,000 years ago of 130 ± 300 metres lower than at present." https://en.wikipedia.org/wiki/Greenland_ice_sheet#Observation_and_research_since_2010 https://en.wikipedia.org/wiki/Greenland_ice_sheet#Observatio...
