For the second consecutive year, winter sea ice in the Arctic reached a level that matches the lowest peak observed since satellite monitoring began in 1979. On March 15, Arctic sea ice extent reached 5.52 million square miles (14.29 million square kilometers), very close to the 2025 peak of 5.53 million square miles (14.31 million […]

Patagonia Glacier retreat, Chile
Patagonia, Chile. Left: September 18, 1986. Right: August 5, 2002. The 1986 image shows the region prior to a major retreat of the glaciers. The 2002 image shows a retreat of nearly 10 kilometers (6.2 miles) of the glacier on the left side. The smaller glacier on the right has receded more than 2 kilometers (1.2 miles). In front of the smaller glacier, two ribbon lakes have formed behind the debris left by the glacier’s advance. Scientists and government managers are using satellite imagery like this to monitor the retreat of the glaciers and the impact on water bodies caused by the changes in the glaciers’ size and direction.
