An international team of experts brought together by ESA and NASA has produced the most accurate assessment, with the clearest evidence yet of Polar ice losses, from Antarctica and Greenland. Image credit: Ian Joughin, University of Washington
Blood Falls seeps from the end of the Taylor Glacier into Lake Bonney in the Antarctic. Scientists believe a buried saltwater reservoir is partly responsible for the discoloration, which is a form of reduced iron. The tent at left provides a sense of scale for just how big the phenomenon is. Photo by Peter Rejcek, courtesy of the National Science Foundation, Wikimedia Commons
This photo of the Hubbard Glacier in southeastern Alaska was taken from a cruise ship about an eighth of a mile (0.2 km) away. Stretching out to 76 mi (122 km) in length and 7 mi (11 km) in width, at its widest, Hubbard is the largest tidewater glacier in North America. Image credit: Vince DeFrancisci; Vince’s Web site
The Pamir Mountains in eastern Tajikistan, include some of the world’s highest peaks, soaring to heights of 7,300 meters (24,000 feet ). They are part of the “roof of the world”, home to thousands of glaciers. Among them is Fedchenko, which at 77 kilometers (47 miles) is the longest glacier outside of the Earth’s polar regions.

An iceberg, or ice island, twice the size of Manhattan has broken away from the Petermann Glacier in northern Greenland. Images from Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite show the island breaking off a tongue of ice that extends at the end of the glacier.
In the image you can see a meltwater pond nestled amid the rock-and-ice covered fringe of Greenland. Most of the surface of Greenland is covered with fresh water—about 2.6 million cubic kilometers of it. Yet that water is frozen, locked up in ice and snow.

The Columbia Glacier descends from an ice field 3,050 meters (10,000 feet) above sea level, down the flanks of the Chugach Mountains, and into a narrow inlet that leads into Prince William Sound in southeastern Alaska. It is one of the most rapidly changing glaciers in the world.
