NASA has published a time lapse video that recounts the history of Ice Age glaciers starting from 122,000 years ago. The animation is based on a new model of glacier movements and the response of the Earth’s land masses. The animation was created by scientists at the University of Toronto and NASA’s Jet Propulsion Laboratory.
According to an accompanying article, the model is helping scientists understand postglacial rebound, also known as glacial isostatic adjustment, which refers to the way land masses rebound when heavy glaciers melt and disappear from the surface. This factor is crucial in predicting the rise of sea level over time.
