A 1992 to 1998 observation of the Chacaltaya Glacier in Bolivia and Antizana Glacier in Ecuador indicate that between 0.6 m (2.0 ft) and 1.9 m (6.2 ft) of ice was lost per year on each glacier. Figures for Chacaltaya show a loss of 67% of its volume and 40% of its thickness over the same period.
Fragments of Larsen B ice shelf lingered until 2005. Radiocarbon dating has been used to date the start of glacial retreat on Alexander Island 18,000 years ago. [1] The outermost locations like Marguerite Bay were fully deglaciated 12,000 years ago and the further inland locations continued deglaciating for an additional 3,000 years. [1]
The Red Eagle Glacier in Montana, following a century of retreat, has dropped below the threshold of an active glacier and become a mere glacieret. [6] Shepard Glacier in Glacier National Park converted to a glacieret in 2009. [7] There are many glacierets on Mount Kenya, ranging from surface areas of 0.01 to 0.09 km 2. [8] The last glacier of ...
Athabasca Glacier. Canada. One of North America’s most-visited glaciers is also one of its most vulnerable. Athabasca, in Alberta’s Jasper National Park, is retreating about 16 feet every year ...
EIS imagery has appeared in time-lapse videos displayed in the terminal at Denver International Airport; in media productions such as the 2009 NOVA Extreme Ice documentary on PBS; [1] and is the focus of the feature-length film Chasing Ice, directed by Jeff Orlowski, [2] which premiered at the Sundance film festival in Utah on January 23, 2012.

While no glaciers disappeared between 1980 and 1990, the 25 years after 1990 showed 35 glaciers had disappeared. In total, the glacier area has decreased by 45% compared to 1980.

The "Doomsday Glacier," roughly the size of the state of Florida, is one of the largest glaciers in the world. Scientists predict that its collapse could contribute to 65 centimeters, or roughly ...
