Hot weather has engulfed a huge portion of the Arctic, from Alaska to Greenland to Siberia. Yet another symptom of an Arctic transitioning into a more volatile state as the planet warms.
Rapid changes in terrain are taking place in Canada's high Arctic polar deserts due to increases in summer air temperatures.
The research has found that even if the world were to cut emissions in line with the Paris agreement, winter temperatures in the Arctic would rise above 3.5 degrees Celsius by 2050 and 5.9 degrees Celsius by 2080.
Scientists that studied the Western Canada’s permafrost, which is more ice-and sediment-rich than others, discovered that this permafrost meltwater contains sulfuric acid.
Arctic sea ice isn't just threatened by the melting of ice around its edges, a new study has found: Warmer water that originated hundreds of miles away has penetrated deep into the interior of the Arctic.
The oldest and thickest sea ice in the Arctic zone north of Greenland is splitting in a never-before-seen event. For the second time this year, the frozen waters cracked open to reveal the sea beneath them.
A new NASA-led experiment measured a key component of the Arctic’s energy balance from space for the very first time.
As frigid air sweeps across Europe, the Arctic itself is seeing an unprecedented warm spell.
The tundra of Eurasia and North America contains twice as much mercury as the rest of the world combined.
When the strong winds that circle the Arctic slacken, cold polar air can escape and cause extreme winter chills in parts of the Northern hemisphere - a new study finds.
The World Meteorological Organization will scrutinize Arctic and Antarctic to minimize risks linked to rapid climate change.
