[[Greenland]] is located between the [[Arctic Ocean]] and the North [[Atlantic Ocean]], northeast of [[Canada]] and northwest of [[Iceland]]. The territory comprises the [[island]] of Greenland—the [[List of islands by area|largest island in the world]]—and more than a hundred other smaller islands (see [[:Category:Islands of Greenland|alphabetic list]]). Greenland has a {{convert|1.2|km||sp=us|adj=mid|-long}} border with Canada on [[Hans Island]].<ref>{{Cite web |date=2022-06-14 |title=On tiny Hans Island, Denmark and Canada create world's newest land border |url=https://bigthink.com/strange-maps/hans-island-border/ |access-date=2023-07-07 |website=Big Think |language=en-US}}</ref> A sparse population is confined to small settlements along certain sectors of the coast.

The vegetation is generally sparse, with the only patch of forested land being found in [[Municipality of Nanortalik|Nanortalik Municipality]] in the extreme south near [[Cape Farewell, Greenland|Cape Farewell]].

The [[Polar climate|climate is arctic]] to [[Subarctic climate|subarctic]], with cool summers and cold winters. The terrain is mostly a flat but gradually sloping icecap that covers all land except for a narrow, mountainous, barren, rocky coast. The lowest elevation is [[sea level]] and the highest elevation is the summit of [[Gunnbjørn Fjeld]], the highest point in the [[Arctic]] at {{convert|3694|m|sp=us}}. The northernmost point of the island of Greenland is [[Cape Morris Jesup]], discovered by Admiral [[Robert Peary]] in 1900. [[Natural resource]]s include [[zinc]], [[lead]], [[iron]] ore, [[coal]], [[molybdenum]], [[gold]], [[platinum]], [[uranium]], [[hydropower]] and [[fish]].

Greenland's climate is a [[tundra climate]] on and near the coasts and an [[ice cap climate]] in inland areas. It typically has short, cool summers and long, moderately cold winters.

Due to [[Gulf Stream]] influences, Greenland's winter temperatures are very mild for its latitude. In [[Nuuk]], the capital, average winter temperatures are only {{cvt|-9|C|F}}.<ref name ="nuuk-climate">{{cite web|archive-url=https://web.archive.org/web/20190210040507/https://www.dmi.dk/fileadmin/user_upload/Rapporter/TR/2019/DMIRep18-19.pdf|archive-date=10 February 2019|url=https://www.dmi.dk/fileadmin/user_upload/Rapporter/TR/2019/DMIRep18-19.pdf|title=DMI Report 18–19: Climatological Standard Normals 1981–2010 Denmark, The Faroe Islands and Greenland Based on Data Published in DMI Reports 18–08, 18–04 and 18–05|publisher=[[Danish Meteorological Institute]]|access-date=10 February 2019}}</ref> In comparison, the average winter temperatures for [[Iqaluit]], [[Nunavut]], [[Canada]], are around {{cvt|-27|C|F}}.<ref name="iqaluit-climate">{{cite web|publisher=[[Environment Canada]]|url=http://climate.weather.gc.ca/climate_normals/results_1981_2010_e.html?stnID=1758|id=Climate ID: 2402590|title=Iqaluit A|work=Canadian Climate Normals 1981–2010|access-date=February 24, 2014|url-status=live|archive-url=https://web.archive.org/web/20170516193447/http://climate.weather.gc.ca/climate_normals/results_1981_2010_e.html?stnID=1758|archive-date=May 16, 2017 |date=31 October 2011}}</ref> Conversely, summer temperatures are very low, with an average high around {{cvt|10|C|F}}.<ref name="nuuk-climate" /> This is too low to sustain trees, and the land is treeless [[tundra]].

=== Climate change ===
The Greenland ice sheet is {{convert|3|km|mi|1|sp=us}} thick and broad enough to blanket an area the size of [[Mexico]]. The ice is so massive that its weight presses the bedrock of Greenland below sea level and is so all-concealing that not until recently did scientists discover [[Greenland's Grand Canyon]] or the possibility that Greenland might actually be three islands.<ref name="latimes2006-06-25">[https://www.latimes.com/archives/la-xpm-2006-jun-25-sci-greenland25-story.html "Greenland's Ice Sheet Is Slip-Sliding Away"], ''Los Angeles Times'', June 25, 2006</ref>

If the ice melted, the interior bedrock below sea level would be covered by water. It is not clear whether this water would be at sea level or a lake above sea level. If it would be at sea level it could connect to the sea at [[Ilulissat Icefjord]], in [[Baffin Bay]] and near [[Nordostrundingen]], creating three large islands.<ref>{{cite web|url=http://www.cejournal.net/?p=4225|title=Is the world's fastest-moving glacier set to speed up even more?|publisher=Center for Environmental Journalism|date=October 23, 2010|archive-url=https://web.archive.org/web/20111203051250/http://www.cejournal.net/?p=4225|archive-date=December 3, 2011}}</ref> But it is most likely that it would be a lake with one drain.

It is thought that before the [[Last Glacial Period|last Ice Age]], Greenland had mountainous edges and a lowland (and probably very dry) center which drained to the sea via one big river flowing out westwards, past where [[Disko Island]] is now.<ref>{{cite web|url=https://www.theneweuropean.co.uk/tag/arts-culture/|title=Arts and Culture Archives}}</ref>

There is concern about [[sea level rise]] caused by ice loss (melt and glaciers falling into the sea) on Greenland. Between 1997 and 2003 ice loss was {{convert|68|-|92|km3/a|cumi/a|0|abbr=on}}, compared to about {{convert|60|km3/a|cumi/a|abbr=on}} for 1993/4–1998/9. Half of the increase was from higher summer melting, with the rest caused by the movements of some glaciers exceeding the speeds needed to [[Glacier mass balance|balance upstream snow accumulation]].<ref>Krabill, W., et al., 2004, ''Greenland Ice Sheet: increased Coastal Thinning,'' Geophysical Research Letters, 31 L24402</ref> A complete loss of ice on Greenland would cause a sea level rise of as much as {{convert|6.40|m|ft|sp=us}}.

Researchers at [[NASA]]'s [[Jet Propulsion Laboratory]] and the [[University of Kansas]] reported in February 2006 that the glaciers are melting twice as fast as they were five years prior. By 2005, Greenland was beginning to lose more ice volume than anyone expected – an annual loss of up to {{convert|52|cumi|km3|0|disp=or}} per year, according to more recent satellite gravity measurements released by JPL. The increased ice loss may be partially offset by increased snow accumulation due to increased precipitation.

Between 1991 and 2006, monitoring of the weather at one location (Swiss Camp) found that the average winter temperature had risen almost {{convert|10|F-change|1|lk=on}}.

Recently, Greenland's three largest outlet glaciers have started moving faster, satellite data show. These are the [[Jacobshavn Glacier|Jacobshavn Isbræ]] at Ilulissat (Jacobshavn) on the western edge of Greenland, and the [[Kangerdlugssuaq Glacier|Kangerdlugssuaq]] and [[Helheim Glacier|Helheim]] glaciers on the eastern edge of Greenland. The two latter accelerated greatly during the years 2004–2005, but returned to pre-2004 velocities in 2006.<ref>{{cite journal|title=Rapid Changes in Ice Discharge from Greenland Outlet Glaciers|first1=Ian M.|last1=Howat|first2=Ian R.|last2=Joughin|first3=Ted A.|last3=Scambos|date=8 February 2007|journal=Science|volume=315|issue=5818|pages=1559–61|doi=10.1126/science.1138478|pmid=17289940|bibcode=2007Sci...315.1559H|citeseerx=10.1.1.395.1108|s2cid=27719836}}</ref> The accelerating ice flow has been accompanied by a dramatic increase in seismic activity. In March 2006, researchers at [[Harvard University]] and the [[Lamont–Doherty Earth Observatory]] at [[Columbia University]] reported that the glaciers now generate swarms of earthquakes up to magnitude 5.0.<ref name="latimes2006-06-25" />

The retreat of Greenland's ice is revealing islands that were thought to be part of the mainland. In September 2005 [[Dennis Schmitt]] discovered an island {{convert|400|mi|km|0}} north of the Arctic Circle in eastern Greenland which he named [[Uunartoq Qeqertaq]], [[Inuit language|Inuit]] for "warming island".<ref>[https://www.nytimes.com/2007/01/16/science/earth/16gree.html?ex=1326603600&en=b018c85a1b03d90f&ei=5090&partner=rssuserland&emc=rss "The Warming of Greenland"], ''New York Times'', January 16, 2007</ref>

=== Future projections ===
In the [[Arctic]], temperatures are rising faster than anywhere else in the world. Greenland is losing 200 billion tonnes of ice per year. Research suggests that this could increase the [[sea levels]]' rise by 30 centimeters by the end of the century. These projections have the possibility of changing as satellite data only dates back to 40 years ago. This means that researchers must view old photographs of [[glaciers]] and compare them to ones taken today to determine the future of Greenland's ice.<ref>[http://www.nature.com/news/180-000-forgotten-photos-reveal-the-future-of-greenland-s-ice-1.20335 "180,000 forgotten photos reveal the future of Greenland’s ice"], ''Nature'', July 27, 2016</ref>

== Topography ==
{{See also|List of mountain ranges of Greenland}}The ice sheet covering Greenland varies significantly in elevation across the landmass, rising dramatically between the coastline at sea level and the East-Central interior, where elevations reach {{convert|3200|m|sp=us}}.<ref>{{Cite web|url=https://earthobservatory.nasa.gov/images/5118/topography-of-greenland|title=Topography of Greenland|date=2004-12-26|website=earthobservatory.nasa.gov|language=en|access-date=2018-11-15}}</ref> The coastlines are rocky and predominantly barren with fjords.<ref name=":0">{{Cite web|url=https://www.worldatlas.com/webimage/countrys/namerica/greenland/glland.htm|title=Greenland Landforms and Land Statistics|website=www.worldatlas.com|language=en|access-date=2018-11-15}}</ref> Numerous small islands spread from the Central to Southern coastlines.<ref name=":0" />

Greenland's mountain ranges are partially or completely buried by ice. The highest mountains are in the Watkins Range, which runs along the eastern coast. Greenland's highest mountain is [[Gunnbjørn Fjeld|Gunnbjorn Fjeld]] with a height of {{convert|3700|m|0|sp=us}}.<ref name=":0" />

Scientists discovered an asteroid [[impact crater]] in the northwestern region of Greenland, buried underneath the ice sheet. At a size larger than [[Washington, D.C.]], it is the first impact crater found beneath one of Earth's ice sheets.<ref>{{Cite news|url=https://www.nytimes.com/2018/11/14/science/greenland-ice-crater.html |archive-url=https://ghostarchive.org/archive/20220102/https://www.nytimes.com/2018/11/14/science/greenland-ice-crater.html |archive-date=2022-01-02 |url-access=limited |url-status=live|title=Ice Age Asteroid Crater Discovered Beneath Greenland Glacier|work=The New York Times |date=14 November 2018 |access-date=2018-11-15|language=en |last1=Fleur |first1=Nicholas St }}{{cbignore}}</ref>

==Extreme points==
This is a list of the extreme points of [[Greenland]], the points that are farther north, south, east or west than any other location.

===Territory of Greenland===

* Northernmost point — [[Kaffeklubben Island]] (83°40'N) – the [[Extreme points of Earth|northernmost]] permanent land in the world. There are also some shifting gravel bars that lie north of Kaffeklubben, the most northerly ever found being [[83-42]].
* Southernmost point — unnamed islet 2.3&nbsp;km south of [[Cape Farewell, Greenland|Cape Farewell]], [[Egger Island]] (59°44'N)
