Extreme Ice Survey

Since 2007, the Extreme Ice Survey (EIS) has told the story of a planet in flux. With innovative methodology that combines time-lapse imagery with cutting-edge science, EIS is making the world's most extensive ground-based photographic glacier study. More than 500,000 photographs reveal the extraordinary ongoing retreat of glaciers and ice sheets due to climate change, providing scientists with vital insight on glacier dynamics. EIS has installed 34 time-lapse cameras at 18 glaciers in Greenland, Iceland, Nepal, Alaska, and the Rocky Mountains and conducts annual or bi-annual repeat photography in Iceland, British Columbia, the Alps, and Bolivia. The EIS team has been the subject of a PBS documentary, a National Geographic book, and numerous magazine and newspaper articles. In addition, EIS has been spreading the word about how the world's shrinking glaciers are a manifestation of climate change through public talks, a touring exhibition, displays in public venues including Denver International Airport, appearances before Congress, and multimedia presentations at scientific and policy making conferences.

Icebergs 200 feet tall, formerly part of the Greenland Ice Sheet, float into the North Atlantic Ocean, raising sea levels as they melt.

As the Arctic gets warmer, more meltwater flows out to sea, carving enormous canyons like this one.
