Alaska's Melting Glaciers Form New Island, Satellite Images Capture the Change
A new island has formed in Alaska after the Alsek Glacier retreated over 40 years, surrounding a rocky mound called Prow Knob with meltwater, a process accelerated by global warming. Satellite images from 1984 to 2025 show the glacier's retreat and the growth of Alsek Lake, highlighting the impact of climate change on landscape and sea levels.
