Melting glacier creates a new island in Alaska

A melting glacier in southeastern Alaska has birthed a brand-new island in the middle of a growing lake, according to recent images captured by NASA satellites.

The 2-square-mile island is a small mountain known as Prow Knob, which was once surrounded by a frozen expanse known as the Alsek Glacier. As the glacier thawed and retreated , meltwater flooded the region.

This summer, satellites observed Prow Knob as it was finally stranded as a lone landmass within the expanding Alsek Lake.

This type of transformation is a hallmark of climate change , as rising temperatures and melting ice reshape coastlines around the world and sometimes alter landscapes in dramatic ways .

NASA’s Landsat 5 satellite snapped images of Prow Knob in July 1984, showing that part of the mountain’s western
