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.

Researchers have found a small piece of a "lost continent" buried underneath the lava on Mauritius.

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.
Inuits are less likely to develop cardiovascular disease and diabetes, despite their large fat intake.
A genetic study of Inuits in Greenland has shed light on how this population has adapted to eating a high-fat diet.
Gathering data at the calving front of the Ilulissat Glacier, Greenland.
To create accurate models that predict how ice sheets and oceans will react to changing climate, modelers need precise current data. One researcher heads to the ends of the earth to collect just that.

Loss of sea ice near Greenland and Iceland portend a colder future for Europe.
Rising sea levels are one of the clearest and most widespread manifestations of climate change.
Since 1993, satellites have been used as well as tidal gauges to monitor sea level. A new calibration of this satellite record now shows that the rise in sea level is gathering pace.
Any talk of a Scottish federation should be put on ice.
First the No victory in the Scottish referendum, now the debate about how much extra power should be extended north of the border. While the commission tasked with coming up with proposals prepares to…
It may already be too late to stop Antarctic ice sliding into the ocean.
Ice sheets respond slowly to changes in climate, because they are so massive that they themselves dominate the climate conditions over and around them. But once they start flowing faster towards the shore…
There is an enormous mass of ice beneath the Greenland ice sheet, which has melted and refrozen making the sheet ragged and…
The Greenland icecap will contribute more to rising seas than previously understood, thanks to exposure to warm waters. Using…
The receding edge of the Greenland ice sheet.
Warming in the Arctic has now reached the northernmost sections of the Greenland ice sheet. After a long period of stability (more than 25 years), we have found in a new study of the region that the northeast…
