| Title |
Mount Kilimanjaro's Vanishing Snow Cap (WMS) |
| Abstract |
During the last few decades, the permanent snow and ice on the summit of Mount Kilimanjaro has almost completely disappeared, at the rate of about a foot and a half of glacial ice lost per year. This loss is primarily due to increasing average annual temperatures in the region, and scientists are speculating that the glaciers could be completely gone from Kilimanjaro by the year 2015. This ice cap formed more than 11,000 years ago, and 80% of the ice fields have been lost in only the last century. The shrinkage is illustrated here in Landsat images from 1993, 2000, and 2002, with the 1993 image showing a significant ice cap and the more recent images showing only small glaciers and snow regions remaining. |

Jakobshavn Glacial Floe
| Title |
Jakobshavn Glacial Floe |
| Abstract |
Jakobshavn Isbrae holds the record as Greenland's fastest moving glacier and major contributor to the mass balance of the continental ice sheet. Starting in late 2000, following a period of slowing down in the mid 1990s, the glacier showed significant acceleration and nearly doubled its discharge of ice. |

Jakobshavn Glacier Calving Front Recession from 1850 to 2006 |
| Abstract |
Jakobshavn Isbrae is located on the west coast of Greenland at Latitude 69 N. The ice front, where the glacier calves into the sea, receded more than 40 km between 1850 and 2006. Between 1850 and 1964 the ice front retreated at a steady rate of about 0.3 km/yr, after which it occupied approximately the same location until 2001, when the ice front began to recede again, but far more rapidly at about 3 km/yr. After 2004, the glacier began retreating up its two main tributaries: one to the north, and a more rapid one to the southeast. These changes are important for many reasons. As more ice moves from glaciers on land into the ocean, it causes a rise in sea level. Jakobshavn Isbrae is Greenland's largest outlet glacier, draining 6.5 percent of Greenland's ice sheet area. The ice stream's speed-up and near-doubling of the ice flow from land into the ocean has increased the rate of sea level rise by about .06 millimeters (about .002 inches) per year, or roughly 4 percent of the 20th century rate of sea level increase. |
