For years, Greenland has been painted as a frozen, empty white blob on the map. Yet scientists, military planners and mining companies now view it as one of the most dynamic and strategically sensitive places on Earth, both for its changing climate and its hidden resources.
Greenland, the giant island that refuses to fit the stereotype
Greenland is huge: more than two million square kilometres, making it the largest island on the planet. Around 81% of that is covered by ice, a vast white shield that can reach three kilometres thick.
Greenland is not a single sheet of lifeless ice. Almost one fifth of the island is ice-free land, roughly the size of three quarters of France.
Those ice-free zones hug the coasts, especially in the south and along parts of the west and east. They form a belt of tundra with grasses, moss, and low shrubs. In summer, sheep graze there, a few hardy horses roam, and locals complain less about snow and more about clouds of flies and mosquitoes.
Walk through Nuuk, the capital, in late June and you see something that clashes with the “eternal winter” cliché: green slopes, colourful houses, children on bikes and, on the warmest days, people in T-shirts.
Myth 1: Greenland is entirely frozen, all year round
The numbers are stark but misleading. Ice dominates, yet the remaining land area is far from marginal. These coastal strips are where almost all 56,000 or so residents live, work and travel between small settlements and fishing grounds.
The hidden landscapes under the ice-line
South Greenland in particular looks surprisingly familiar to visitors from Scotland, Norway or northern Canada. Rocky hills, patches of green, and small fjords give space for:
- Sheep farming in sheltered valleys
- Small vegetable plots during the short summer
- Hiking routes across tundra and low mountains
- Scientific stations monitoring the ice sheet edge
These relatively mild coastal areas are the reason Greenland has always been more than an ice desert, from the days of the Norse settlers to today’s modern fishing towns.
Myth 2: it is always brutally cold in Greenland
There is no escaping it: large parts of Greenland are intensely cold. In winter, interior temperatures can plunge below -50°C. The World Meteorological Organization recognises a reading of -69.6°C in December 1991 as the lowest temperature ever observed in the Northern Hemisphere.

Yet that headline figure hides another truth. The southern tip of Greenland lies farther south than Iceland. That lower latitude, combined with coastal influences, makes summers there surprisingly gentle by Arctic standards.
Summer afternoons between 15°C and 20°C are not rare in southern Greenland, and some locations have broken 30°C.
Nuuk recorded 24°C on 9 June 2016, a striking contrast with its usual June afternoon average of around 8°C. In Ivittuut, in the southwest, the summer afternoon average is about 12°C. On 23 June 1915, Ivittuut hit 30.1°C, a national heat record that still stands and sits about 18°C above the June norm.
When Greenland heats up fast
These spikes in warmth are linked to particular weather patterns. A strong southerly airflow can drag warmer air masses up towards the island. If the skies are clear, the high-angle summer sun can warm bare ground quickly in the ice-free areas.
For visitors who pack only heavy polar gear, those days can be a shock. Locals know they might need a winter jacket in the morning and a light shirt by afternoon.
Myth 3: no trees can grow in Greenland
Greenland is not a place of tall, dense forests, but it is not entirely treeless either. Along parts of the coast, pockets of woodland survive and even expand.
You can find native species such as junipers, alders, willows and birches, often growing low and twisted by wind. On top of that, foresters and researchers have introduced pines, spruces, poplars and other hardy species in experimental plots and small plantations.
Over just 30 years, the area covered by vegetation in Greenland is estimated to have more than doubled, from about 34,000 to nearly 87,500 square kilometres.
Those figures, from researchers at the University of Leeds, show how quickly a warming climate can transform polar landscapes. Shrubs push farther north and higher up slopes, grasses colonise new ground, and what used to be bare gravel can turn patchily green.
Greenland becoming green again
Palaeoclimate records suggest Greenland was once much greener thousands of years ago, before the ice reached its current extent. Rising temperatures are nudging it back in that direction, though this “greening” comes with serious consequences: thawing permafrost, unstable slopes and faster meltwater flows from the ice sheet.
Myth 4: the ice makes most of Greenland uninhabitable
That claim is only partly true. The thick interior ice sheet does block roads and farming. No one lives permanently on top of the central ice dome, and large areas remain logistically inaccessible.
Yet settlements exist far beyond the milder south. Even in the far north, places like Qaanaaq, with only a few hundred inhabitants, keep going despite winter mornings between -25°C and -40°C from October to May. Communities depend on hunting, fishing and careful planning around sea ice conditions.
The coasts also host a string of former and current military installations, from American air bases to radar sites, taking advantage of Greenland’s strategic position between North America and Eurasia.
As the ice sheet retreats, more land, more sea routes and more mineral-rich rocks are exposed, drawing intense interest from major powers.
Since 1985, Greenland has lost roughly 5,000 square kilometres of ice area, equivalent to about a billion tonnes of ice. That retreat feeds global sea-level rise but also opens passages for ships and access to potential deposits of rare earth elements, uranium, and other valuable minerals.
New opportunities, new threats
Industry and governments see prospects in:
- Longer shipping seasons through Arctic waters
- New mining projects on ice-free ground
- Expanded fishing zones as ecosystems shift
- Tourism focused on glaciers, wildlife and Northern Lights
At the same time, the island faces growing hazards. Beyond fierce winds and blizzards, scientists are documenting an increase in so-called “glacial earthquakes”. These are seismic events triggered by sudden movements of large ice masses, such as the collapse of a glacier front or a rapid sliding event at its base.
Such events can damage infrastructure, disrupt ports and pose risks to mines and research stations built too close to unstable ice fronts.
What makes Greenland’s climate so unusual?
Greenland sits partly within the Arctic Circle, straddling the North Atlantic and the Arctic Ocean. Its latitude means extreme contrasts between summer light and winter darkness, which strongly shapes temperature, sea ice and wildlife cycles.
The thick ice sheet itself helps drive weather. It acts like a cold dome, influencing wind patterns, storm tracks and cloud formation. Coastal areas feel the competing pull of that cold interior and relatively milder ocean air, leading to sharp local differences over short distances.
Climate models show that as global greenhouse gas emissions rise, the balance across Greenland shifts. Warmer air and ocean water attack the edges of the ice sheet, while snowfall patterns on top of the ice change. That combination affects how quickly the ice shrinks, and how much fresh water flows into the surrounding seas.
Key terms that reshape how we think about Greenland
Several basic scientific concepts help clarify what is happening on the island:
| Term | Short explanation |
|---|---|
| Latitude | Distance from the equator. Higher latitude means less direct sunlight and colder average temperatures. |
| Climate | Long-term patterns of temperature, rain, wind and other conditions, not just daily weather. |
| Permafrost | Ground that stays frozen for at least two consecutive years. Thawing can destabilise buildings and roads. |
| Ice sheet | A mass of land ice larger than 50,000 km². Greenland’s ice sheet is the second largest on Earth. |
When these pieces interact, they create feedback loops. Darker ground exposed by melting ice absorbs more sunlight, which leads to further local warming. Expanding vegetation can lock away some carbon, yet thawing permafrost may release greenhouse gases, including methane, into the atmosphere.
What this changing climate means for the rest of us
Greenland’s climate is not just a curiosity for polar scientists. If the island’s ice sheet were to melt entirely, global sea level would rise by around seven metres. No serious model predicts that within this century, but partial melt already contributes millimetres to the rise measured along coasts from Florida to Bangladesh.
More subtle shifts also matter. Freshwater from melting ice can affect ocean circulation, including the Atlantic currents that help keep western Europe relatively mild. Changes in sea ice and snow cover can alter how much heat the Arctic sends south, influencing storm tracks over North America and Europe.
For travellers, Greenland offers a rare mix: one of the coldest places on Earth, where a summer hike in a green valley can sit just a few hours’ boat ride from a glacier that records ancient atmospheres in trapped bubbles of ice. For policymakers, the island is a test case of how quickly the planet’s frozen regions can transform once long-held climate assumptions prove wrong.
