Greenland and Denmark have a complicated history, but the connection runs deeper than economic convenience.
The coast of Greenland is not for sale.
The USA has a long colonial history – as does Denmark. The USA has even tried to buy Greenland before. But this time, Greenland isn't Denmark's to sell.
Most of Greenland is covered by Arctic ice.

In 1867, the US bought Alaska from Tsar Alexander II for a tidy sum of $7.2 million. Trump probably wouldn't be able to get that kind of bargain for Greenland.
Smoke from wildfires in Siberia drifts east toward Canada and the U.S. on July 30, 2019.
A researcher based in Fairbanks, Alaska, links 2019's record-breaking wildfires in far northern regions of the world to climate change, and describes what it's like as zones near her city burn.

Greenland's ice made headlines in June, as warm weather made for unseasonably widespread melting. And though this summer is still unfolding, the human fingerprint on Greenland's ice can't be denied.
A small boat in the Illulissat Icefjord is dwarfed by the icebergs that have calved from the floating tongue of Greenland’s largest glacier, Jacobshavn Isbrae.
Sea levels could rise by two metres by 2100, sparking a refugee crisis unlike anything the world has ever seen.
A new climate model combines data on ice loss from both polar regions for the first time.
Climate scientist predict that the combined effect of ice loss in Greenland and Antarctica will be more extreme weather, with impacts on agriculture, infrastructure and human life itself.
An ice-sheet in Greenland’s Inglefield Land is hiding the Hiawatha crater.

Meteorite impacts have fundamentally shaped the history of our planet.
The general health of Greenlandic children is now as good as that of their European peers – perhaps even better.
Scientists on Arctic sea ice in the Chukchi Sea, surrounded by melt ponds, July 4, 2010.
Climate change is transforming the Arctic, with impacts on the rest of the planet. A geographer explains why he once doubted that human actions were causing such shifts, and what changed his mind.

With all eyes on China's intentions in the Arctic, Singapore is flying under the radar. But the tiny Asian nation is also pursuing its own interests in the Arctic.

In what came to be known as the Thule incident, an American bomber crashed in Greenland, spreading radioactive wreckage across 3 square miles of a frozen fjord. Denmark was not happy.

The ice sheet is melting and permafrost is thawing. What's happening in Greenland will speed up climate change across the world.
Water mass enters the ocean from glaciers such as this along the Greenland coast.
Greenland's ice is largely responsible for the accelerating pace of sea-level rise. A new analysis shows that, while Greenland accounted for just 5% of the rise in 1993, that figure rose to 25% by 2014.
Mauritius beachfront view with volcanic mountains. The basaltic lavas constituting these mountains formed no older than 9 million years ago.

Researchers have found a small piece of a "lost continent" buried underneath the lava on Mauritius.
From Norway with love.
An object lesson in seasonal geopolitics.
The crew of scientists prepare to put the drill stem into the Greenland ice sheet to probe water flows about a half of a mile below.
A glaciologist develops a lightweight method for probing the depths of Greenland's ice sheet to answer a crucial question: How fast is it melting?
If life survived on Earth 3.7 billion years ago, why not elsewhere in the solar system?
Scientists say they've found fossils showing life existed on Earth 3.7 billion years ago. How good is the evidence? And what does it mean for the search for life elsewhere in our solar system?
Glaciers have been a major contributor to sea-level rise.
Could sea levels really rise by several metres this century. Probably not, although this century's greenhouse emissions could potentially set the stage for large rises in centuries to come.
We still don’t know enough about questions such as where the tipping points are for Arctic ice melt.

The Paris agreement has given us some solid targets to aim for in terms of limiting global warming. But that in turn begs a whole range of new scientific questions.
