Retreat of glaciers since 1850 <=SEP=> 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 . Studied by glaciologists , the temporal coincidence of glacier retreat with the measured increase of atmospheric greenhouse gases is often cited as an evidentiary underpinning of global warming . Mid-latitude mountain ranges such as the Himalayas , Alps , Rocky Mountains , Cascade Range , 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 .   Glacier mass balance is the key determinant of the health of a glacier . If the amount of frozen precipitation in the accumulation zone exceeds the quantity of glacial ice lost due to melting or in the ablation zone a glacier will advance ; if the accumulation is less than the ablation , the glacier will retreat . Glaciers in retreat will have negative mass balances , and if they do not find an equilibrium between accumulation and ablation , will eventually disappear .   The Little Ice Age was a period from about 1550 to 1850 when the world experienced relatively cooler temperatures compared to the present . Subsequently , until about 1940 , glaciers around the world retreated as the climate warmed substantially . Glacial retreat slowed and even reversed temporarily , in many cases , between 1950 and 1980 as global temperatures cooled slightly . Since 1980 , a significant global warming has led to glacier retreat becoming increasingly rapid and ubiquitous , so much so that some glaciers have disappeared altogether , and the existences of many of the remaining glaciers are threatened . In locations such as the Andes of South America and Himalayas in Asia , the demise of glaciers in these regions has the potential to affect water supplies in those areas .   The retreat of mountain glaciers , notably in western North America , Asia , the Alps and tropical and subtropical regions of South America , Africa and Indonesia , provide evidence for the rise in global temperatures since the late 19th century . The acceleration of the rate of retreat since 1995 of key outlet glaciers of the Greenland and West Antarctic ice sheets may foreshadow a rise in sea level , which would affect coastal regions .

Mount Kenya <=SEP=> Mount Kenya is the highest mountain in Kenya and the second-highest in Africa , after Kilimanjaro . The highest peaks of the mountain are Batian ( 5199 m ) , Nelion ( 5188 m ) and Point Lenana ( 4985 m ) . Mount Kenya is located in central Kenya , the heart of Kenya , about 16.5 km south of the equator , around 150 km north-northeast of the capital Nairobi . Mount Kenya is the source of the name of the Republic of Kenya .   Mount Kenya is a stratovolcano created approximately 3 million years after the opening of the East African rift .  Before glaciation , it was 7000 m high . It was covered by an ice cap for thousands of years . This has resulted in very eroded slopes and numerous valleys radiating from the centre . There are currently 11 small glaciers . The forested slopes are an important source of water for much of Kenya .   There are several vegetation bands from the base to the summit . The lower slopes are covered by different types of forest . Many alpine species are endemic to Mount Kenya , such as the giant lobelias and senecios and a local subspecies of rock hyrax . An area of 715 km2 around the centre of the mountain was designated a National Park  and listed as a UNESCO World Heritage Site in 1997 . The park receives over 16,000 visitors per year .

Mount Kilimanjaro <=SEP=> Mount Kilimanjaro ( -LSB- pronˌkɪlɪmənˈdʒɑːroʊ -RSB- ) , with its three volcanic cones , `` Kibo '' , `` Mawenzi '' , and `` Shira '' , is a dormant volcano in Tanzania . It is the highest mountain in Africa , and rises approximately 4900 m from its base to 5895 m above sea level.The first persons proven to have reached the summit of the mountain were Hans Meyer , and Ludwig Purtscheller in 1889 . The mountain is part of the Kilimanjaro National Park and is a major climbing destination . The mountain has been the subject of many scientific studies because of its shrinking glaciers and disappearing ice fields .
