Geological fingerprint suggests rapid glacier retreat

At the end of the last ice age, geological fingerprints recorded in ocean sediments suggests glacier retreat of 50 meters a day, 18 km a year. For comparison the fastest retreating glaciers in Antarctica today are the Pope, and the Smith glacier system, retreating about 2.9 km a year. https://climatestate.com/2020/08/03/geological-fingerprint-suggest-rapid-glacier-retreat/
