Specifically, since the industrial revolution, carbon dioxide and other greenhouse gas emissions have raised temperatures, even higher in the poles, and as a result, glaciers are rapidly melting, calving off into the sea and retreating on land. The regions currently losing mass fastest are Arctic Canada North, Alaska, and glaciers around the periphery of the Greenland Ice Sheet. The GIF below is a series of Landsat images from 1986 to 2019. Trends for the four U.S. referenceglaciers are consistent with the retreat of glaciers observed throughout the western United States, Alaska, and other parts of the world. It flows through the Chugach Mountains to Prince William Sound. Because rocks of that age are rare, we don't know much about the intensity or global extent of this glaciation. Juneau Some scientists attribute this massive glacial retreat to the Industrial Revolution, which began around 1760. We dont know how many glaciers there were in 1948, Ben Marzeion, a climate scientist and professor at the University of Bremen, said.
