An Arctic ozone hole? Not quite

Since the discovery of the Antarctic ozone hole, scientists, policymakers, and the public have wondered whether we might someday see a similarly extreme depletion of ozone over the Arctic.

Why Arctic ice is disappearing more rapidly than expected

A new study led by Lance Lesack, a Simon Fraser University geographer and Faculty of Environment professor, has discovered unexpected climate-driven changes in the mighty Mackenzie River’s ice breakup. This discovery may help resolve the complex puzzle underlying why Arctic ice is disappearing more rapidly than expected.  

The dynamics behind Arctic ecosystems

The climate – combined with the body size of the herbivores – is crucial for how the tundra’s ecosystem works. This is shown in new research, which is also the first step towards a general understanding of ecosystems on land.

Report: Arctic inland waters emit large amounts of carbon

Geoscientist Erik Lundin shows in his thesis that streams and lakes of Northern Sweden are hotspots for emissions of carbon dioxide and methane into the atmosphere.

Report: Arctic warmth unprecedented in 44,000 years

When the temperature rises on Baffin Island, in the Canadian high Arctic, ancient Polytrichum mosses, trapped beneath the ice for thousands of years, are exposed. Using radiocarbon dating, new research in Geophysical Research Letters has calculated the age of relic moss samples that have been exposed by modern Arctic warming.

High levels of molecular chlorine found in arctic atmosphere

Scientists studying the atmosphere above Barrow, Alaska, have discovered unprecedented levels of molecular chlorine in the air, a new study reports.

Arctic sea ice up from record low

Measurements from ESA’s CryoSat satellite show that the volume of Arctic sea ice has significantly increased this autumn.

Melting Arctic sea ice won't break records

The melting of sea ice in the Arctic is well on its way toward its annual "minimum," that time when the floating ice cap covers less of the Arctic Ocean than at any other period during the year.

Report: Cost of Arctic methane release could be "size of global economy"

Economic modelling shows that the methane emissions caused by shrinking sea ice from just one area of the Arctic could come with a global price tag of 60 trillion dollars - the size of the world economy in 2012.

Massive "greening" of the Arctic predicted by the NSF

The National Science Foundation (NSF) has concluded that rising temperatures will lead to a massive "greening" of the Arctic by mid-century, as a result of marked increases in plant cover.

Towards a drastically greener Arctic

Scientists are currently predicting that rising temperatures will lead to a massive "greening," or increase in plant cover, in the Arctic.

'Winnipeg moves to Minneapolis' as northern US warms

Northern latitudes are greening up, says a NASA-funded study, increasingly resembling the lusher latitudes of the south.

Global warming turned Sandy into superstorm

Last October's Superstorm Sandy was made far worse by the melting of Arctic sea ice, new research suggests.

Were camels originally an Arctic species?

Giant camels once roamed Canada's High Arctic - much further north than previously believed - and may have evolved their flat feet and humps as a result.

Yeti helps out polar explorers

If you need help in snow and ice, who better to ask for help than a yeti?

Ships could soon travel straight across North Pole

Within 50 years, ordinary ships will be able to negotiate shipping lanes through the Arctic Ocean during late summer, new UCLA research shows.

Arctic 'vicious circle' observed affecting greenhouse gases

The widespread decline in Arctic sea ice is causing big changes to the balance of greenhouse gases in the atmosphere, say researchers from Sweden's Lund University.

Sunlight ramps up CO2 production from permafrost

It appears that, when Arctic permafrost melts, it can release carbon dioxide gas into the atmosphere much faster than previously thought.

Arctic debuts Linux-powered XBMC system

Arctic has introduced a Linux-powered system specifically designed to run XBMC's popular Media Center app.

Solar geoengineering 'could be safe'

Solar geoengineering can be safely tailored to manage specific risks like the loss of Arctic sea ice, says a group of researchers keen to persuade the world that such techniques aren't necessarily a disaster waiting to happen.
