Credner Glacier
Credner Glacier is on Mount Kilimanjaro in Tanzania, on the northwest slope of the peak and is a remnant of an icecap which once crowned the top of Mount Kilimanjaro. The glacier is situated at an elevation of between . Credner Glacier is one of the largest glaciers on the mountain and descends from the Northern Ice Field. Credner is rapidly retreating due to its high exposure point on the northwest slope of Mount Kilimanjaro. A report published in 2013 indicated that in another decade the glacier may no longer exist.

Mount Kilimanjaro
Mount Kilimanjaro () is a dormant volcano in Tanzania. It has three volcanic cones: Kibo, Mawenzi, and Shira. It is the highest mountain in Africa and the highest free-standing mountain above sea level in the world: above sea level and about above its plateau base. It is the highest volcano in Africa and the Eastern Hemisphere. Kilimanjaro is the fourth most topographically prominent peak on Earth. It is part of Kilimanjaro National Park and is a major hiking and climbing destination. Because of its shrinking glaciers and ice fields, which are projected to disappear between 2025 and 2035, it has been the subject of many scientific studies. Toponymy The origin of the name Kilimanjaro is not known, but a number of theories exist. European explorers had adopted the name by 1860 and reported that Kilimanjaro was the mountain's Kiswahili name. The 1907 edition of ''The Nuttall Encyclopædia'' also records the name of the mountain as Kilima-Njaro. Johann Ludwig Krapf ...

Tanzania
Tanzania (; ), officially the United Republic of Tanzania ( sw, Jamhuri ya Muungano wa Tanzania), is a country in East Africa within the African Great Lakes region. It borders Uganda to the north; Kenya to the northeast; Comoro Islands and the Indian Ocean to the east; Mozambique and Malawi to the south; Zambia to the southwest; and Rwanda, Burundi, and the Democratic Republic of the Congo to the west. Mount Kilimanjaro, Africa's highest mountain, is in northeastern Tanzania. According to the United Nations, Tanzania has a population of million, making it the most populous country located entirely south of the equator. Many important hominid fossils have been found in Tanzania, such as 6-million-year-old Pliocene hominid fossils. The genus Australopithecus ranged across Africa between 4 and 2 million years ago, and the oldest remains of the genus ''Homo'' are found near Lake Olduvai. Following the rise of '' Homo erectus'' 1.8 million years ago, humanity spread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Cap
In glaciology, an ice cap is a mass of ice that covers less than of land area (usually covering a highland area). Larger ice masses covering more than are termed ice sheets. Description Ice caps are not constrained by topographical features (i.e., they will lie over the top of mountains). By contrast, ice masses of similar size that ''are'' constrained by topographical features are known as ice fields. The ''dome'' of an ice cap is usually centred on the highest point of a massif. Ice flows away from this high point (the ice divide) towards the ice cap's periphery. Ice caps have significant effects on the geomorphology of the area that they occupy. Plastic moulding, gouging and other glacial erosional features become present upon the glacier's retreat. Many lakes, such as the Great Lakes in North America, as well as numerous valleys have been formed by glacial action over hundreds of thousands of years. On Earth, there are about of total ice mass.

Northern Ice Field (Mount Kilimanjaro)
The Northern Ice Field is near the summit of Mount Kilimanjaro in Tanzania, on the west slope of the peak. The Northern Ice Field and Eastern Ice Fields were connected to the Southern Ice Field and formed part of a continuous body of glacial ice atop Mount Kilimanjaro when first scientifically examined in 1912. By 1962 the Southern Ice Field separated from the Northern Ice Field and then by 1975 the Eastern Ice Field did as well. In 1912, the glaciated areas atop Mount Kilimanjaro covered ; by 2011 this had been reduced to , an 85 percent loss. At one time, ice flowing off the Northern Ice Field fed numerous glaciers, including, north to south, the Credner, Drygalski, Great Penck and Little Penck Glaciers. The Northern Ice Field is the largest body of ice remaining on Mount Kilimanjaro, with an area of , when measured in 2007. During the exceptionally cold period known as the Younger Dryas, which occurred approximately 12,800 and 11,500 years BP (between 10,800 and ...

Retreat Of Glaciers Since 1850
The retreat of glaciers since 1850 affects the availability of fresh water for irrigation and domestic use, mountain recreation, animals and plants that depend on glacier-melt, and, in the longer term, the level of the oceans. Deglaciation occurs naturally at the end of ice ages, but glaciologists find the current glacier retreat is accelerated by the measured increase of atmospheric greenhouse gases—an effect of climate change. Mid-latitude mountain ranges such as the Himalayas, Rockies, Alps, Cascades, Southern Alps, and the southern Andes, as well as isolated tropical summits such as Mount Kilimanjaro in Africa, are showing some of the largest proportionate glacial losses. Excluding peripheral glaciers of ice sheets, the total cumulated global glacial losses over the 26 year period from 1993–2018 were likely 5500 gigatons, or 210 gigatons per yr.Fox-Kemper, B., H.T.

List Of Glaciers In Africa
Africa, specifically East Africa, has contained glacial regions, possibly as far back as the last glacial maximum 10,000 to 15,000 years ago. Seasonal snow does exist on the highest peaks of East Africa as well as in the Drakensberg Range of South Africa, the Stormberg Mountains, and the Atlas Mountains in Morocco. Currently, the only remaining glaciers on the continent exist on Mount Kilimanjaro, Mount Kenya, and the Rwenzori.
