Arctic Temperatures in 2019 Second Warmest Ever Recorded

The NOAA report found that the average North Pole temperature from October 2018 to September 2019 was 1.9 degrees Celsius higher than the 1981-2010 average. Scientists have dubbed the warming phenomenon Arctic amplification.

Disappearing Arctic sea ice

This visual representation of the ice age clearly shows how the quantity of older and thicker ice has changed between 1984 and 2016 and how the arctic sea ice is disappearing dramatically.

Satellite Images Show Vast Swathes of the Arctic On Fire

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. 

Widespread permafrost degradation seen in high Arctic terrain

Rapid changes in terrain are taking place in Canada's high Arctic polar deserts due to increases in summer air temperatures.

'No doubt' temperatures in Arctic will rise 3.5C by 2050, says UN

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.

The Arctic's Melting Permafrost Is Now Leaking Acid

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.

'Archived' heat has reached deep into the Arctic interior

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.

Strongest sea ice in the Arctic breaks for the first time

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.

Tiny Satellites to Make Crucial Arctic Climate Measurements For the First Time

A new NASA-led experiment measured a key component of the Arctic’s energy balance from space for the very first time.

Arctic warmer than much of Europe is a worrying sign of climate change

As frigid air sweeps across Europe, the Arctic itself is seeing an unprecedented warm spell.

Has the Arctic Finally Reached a Tipping Point?

The recent wave of mild, humid air and its attendant impacts is disturbing. But this is the fourth winter where we’ve seen a veritable heat wave rack the Arctic.

Melting Arctic Permafrost Could Release Millions of Gallons of Mercury

The tundra of Eurasia and North America contains twice as much mercury as the rest of the world combined.

Winter cold extremes linked to high-altitude polar vortex weakening

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.

UN Launches Polar Weather Study to Prepare for Radical Climate Shifts

The World Meteorological Organization will scrutinize Arctic and Antarctic to minimize risks linked to rapid climate change.
