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 .

Glacier <=SEP=> A glacier ( -LSB- pronˈɡleɪʃər -RSB- or -LSB- ˈɡlæsiə -RSB- ) is a persistent body of dense ice that is constantly moving under its own weight ; it forms where the accumulation of snow exceeds its ablation ( melting and sublimation ) over many years , often centuries . Glaciers slowly deform and flow due to stresses induced by their weight , creating crevasses , seracs , and other distinguishing features . They also abrade rock and debris from their substrate to create landforms such as cirques and moraines . Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water .   On Earth , 99 % of glacial ice is contained within vast ice sheets in the polar regions , but glaciers may be found in mountain ranges on every continent except Australia , and on a few high-latitude oceanic islands . Between 35 ° N and 35 ° S , glaciers occur only in the Himalayas , Andes , Rocky Mountains , a few high mountains in East Africa , Mexico , New Guinea and on Zard Kuh in Iran . Glaciers cover about 10 percent of Earth 's land surface . Continental glaciers cover nearly 5 e6sqmi or about 98 percent of Antarctica 's 5.1 e6sqmi , with an average thickness of 7,000 ft. Greenland and Patagonia also have huge expanses of continental glaciers .   Glacial ice is the largest reservoir of fresh water on Earth . Many glaciers from temperate , alpine and seasonal polar climates store water as ice during the colder seasons and release it later in the form of meltwater as warmer summer temperatures cause the glacier to melt , creating a water source that is especially important for plants , animals and human uses when other sources may be scant . Within high altitude and Antarctic environments , the seasonal temperature difference is often not sufficient to release meltwater .   Because glacial mass is affected by long-term climatic changes , e.g. , precipitation , mean temperature , and cloud cover , glacial mass changes are considered among the most sensitive indicators of climate change and are a major source of variations in sea level .   A large piece of compressed ice , or a glacier , appears blue as large quantities of water appear blue . This is because water molecules absorb other colors more efficiently than blue . The other reason for the blue color of glaciers is the lack of air bubbles . Air bubbles , which give a white color to ice , are squeezed out by pressure increasing the density of the created ice .

Greenland <=SEP=> Greenland ( -LSB- ˈɡriːnlənd -RSB- Kalaallit Nunaat -LSB- kaˈlaːɬit ˈnunaːt -RSB- Grønland -LSB- ˈɡ̊ʁɶnˌlanˀ -RSB- ) is an autonomous constituent country within the Kingdom of Denmark between the Arctic and Atlantic Oceans , east of the Canadian Arctic Archipelago . Though physiographically a part of the continent of North America , Greenland has been politically and culturally associated with Europe ( specifically Norway and Denmark , the colonial powers , as well as the nearby island of Iceland ) for more than a millennium . The majority of its residents are Inuit , whose ancestors began migrating from the Canadian mainland in the 13th century , gradually settling across the island .   Greenland is the world 's largest island ( Australia , although larger , is generally considered to be a continental landmass rather than an island ) . Three-quarters of Greenland is covered by the only permanent ice sheet outside Antarctica . With a population of about 56,480 ( 2013 ) , it is the least densely populated country in the world . The Arctic Umiaq Line ferry acts as a lifeline for western Greenland , connecting the various cities and settlements .   Greenland has been inhabited off and on for at least the last 4,500 years by Arctic peoples whose forebears migrated there from what is now Canada . Norsemen settled the uninhabited southern part of Greenland beginning in the 10th century , and Inuit peoples arrived in the 13th century . The Norse colonies disappeared in the late 15th century . Soon after their demise , beginning in 1499 , the Portuguese briefly explored and claimed the island , naming it Terra do Lavrador ( later applied to Labrador in Canada ) . In the early 18th century , Scandinavian explorers reached Greenland again . To strengthen trading and power , Denmark-Norway affirmed sovereignty over the island .   Denmark -- Norway claimed Greenland for centuries . Greenland was settled by Vikings ( of Norwegian origin ) more than a thousand years ago , who had previously settled Iceland to escape persecution from the King of Norway and his central government . Vikings set sail from Greenland and Iceland , encountering North America nearly 500 years before Columbus reached the Caribbean islands . They attempted to colonize land . Though under continuous influence of Norway and Norwegians , Greenland was not formally under the Norwegian crown until 1262 . The Kingdom of Norway was extensive and a military power until the mid-14th century . Norway was dramatically hit with a larger death toll than Denmark by the Black Death , forcing Norway to accept a union in which the central government , university and other fundamental institutions were located in Copenhagen . Thus , the two kingdoms ' resources were directed at creating Copenhagen . Norway became the weaker part and lost sovereignty over Greenland in 1814 when the union was dissolved . Greenland became a Danish colony in 1814 , and was made a part of the Danish Realm in 1953 under the Constitution of Denmark .   In 1973 , Greenland joined the European Economic Community with Denmark . However , in a referendum in 1982 , a majority of the population voted for Greenland to withdraw from the EEC which was effected in 1985 . Greenland contains the world 's largest and most northernly national park , Northeast Greenland National Park ( Kalaallit Nunaanni nuna eqqissisimatitaq ) . Established in 1974 and expanded to its present size in 1988 , it protects 972001 km2 of the interior and northeastern coast of Greenland and is bigger than all but twenty-nine countries in the world . Greenland is divided into four municipalities - Sermersooq , Kujalleq , Qaasuitsup , and Qeqqata .   In 1979 , Denmark had granted home rule to Greenland , and in 2008 , Greenlanders voted in favour of the Self-Government Act , which transferred more power from the Danish royal government to the local Greenlandic government . Under the new structure , in effect since 21 June 2009 , Greenland can gradually assume responsibility for policing , judicial system , company law , accounting , and auditing ; mineral resource activities ; aviation ; law of legal capacity , family law and succession law ; aliens and border controls ; the working environment ; and financial regulation and supervision , while the Danish government retains control of foreign affairs and defence . It also retains control of monetary policy , providing an initial annual subsidy of DKK 3.4 billion , which is planned to diminish gradually over time . Greenland expects to grow its economy based on increased income from the extraction of natural resources . The capital , Nuuk , held the 2016 Arctic Winter Games . At 70 % , Greenland has one of the highest shares of renewable energy in the world , mostly coming from hydropower .

Greenland ice sheet <=SEP=> The Greenland ice sheet ( Grønlands indlandsis , Sermersuaq ) is a vast body of ice covering 1710000 km ² , roughly 80 % of the surface of Greenland .   It is the second largest ice body in the world , after the Antarctic ice sheet . The ice sheet is almost 2400 km long in a north-south direction , and its greatest width is 1100 km at a latitude of 77 ° N , near its northern margin . The mean altitude of the ice is 2135 m . The thickness is generally more than 2 km and over 3 km at its thickest point . It is not the only ice mass of Greenland -- isolated glaciers and small ice caps cover between 76000 and around the periphery . If the entire 2850000 km3 of ice were to melt , it would lead to a global sea level rise of 7.2 m . The Greenland Ice Sheet is sometimes referred to under the term inland ice , or its Danish equivalent , indlandsis . It is also sometimes referred to as an ice cap .
