Giant Viruses Are Infecting Algae in a Rare, Floating Lake in The Arctic

Researchers found "giant" viruses – several times larger than typical viruses – affecting microscopic algae just below the boundary between fresh water and salt water. 

Arctic sea ice isn't freezing in October for the first time

For the first time since records began, the main nursery of Arctic sea ice in Siberia has yet to start freezing in late October. The delayed annual freeze has been caused by extreme warmth. 

World's largest Arctic expedition returns with bad news

After 13 months of collecting data, history’s largest Arctic research expedition returned with grim news. “We witnessed how the Arctic Ocean is dying,” the mission leader said.

Coldest Northern Hemisphere Temperature Record

Nearly after 30 years, the World Meteorological Organization confirms that the Northern Hemisphere in Greenland has a minus minus 69.6 C. This new data provides a benchmark for understanding climate change.

Complete loss of Arctic sea-ice by 2035

High temperatures in the Arctic have puzzled scientists for decades. Now, a new study supports predictions that the Arctic could be free of sea ice by 2035.

Arctic Circle oil spill

An emergency was declared after 20,000 tonnes of diesel leaked into a river when a tank at a power plant near the city of Norilsk, Russia, collapsed at the end of May. The spill contaminated a 350 sq km area.

That Unusually Large Ozone Hole Has Closed Up Again

Earlier this year, most of the ozone around 18 km overhead had vanished completely. But now we can breathe a sigh of relief as its healed up again. However, it's hard to predict just how rising temperatures will affect it in future.

Sea Ice Will Be Gone in Arctic Summers by 2050

A new analysis of numerous climate models predicts the Arctic Ocean will become ice-free in the summer before the mid-point of this century – a startling forecast that persists even if we cut down atmospheric CO2 emissions.

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.
