Arctic wildfire emissions in June and July alone outranked annual figures since 2003, data shows.

Terrifying Arctic greenhouse gas levels continue

The Arctic is expected to have ice-free summers sometime within the next 30 years, largely impacting the state of existing permafrost.

Unlike the Antarctic ozone hole that develops annually during austral spring (September, October, and November), Arctic ozone levels usually stay well above the ozone hole threshold. The Arctic stratospheric vortex is typically too warm for polar stratospheric clouds to form, which are a key ingredient in severe ozone depletion processes. Much stronger planetary wave activity occurs in the Northern Hemisphere than in the Southern Hemisphere, which generates stronger dynamical heating to warm the stratospheric Arctic vortex. Despite this, polar meteorologists reported a record-breaking Arctic "ozone hole" during spring 2020, prompting a research inquiry into what caused this unusual phenomenon.

An Antarctic ice shelf that has existed for thousands of years is about to shed a 1,000-foot-thick (300-metre) block of ice that's roughly the size of Delaware.

Murray Brewster, National Post/Canadian Press, January 11, 2015 OTTAWA — The Canadian military has been routinely deploying a counter-intelligence team to guard against possible spying, terrorism a…

An environmental activist is calling on the U.S. Fish and Wildlife Service to reconsider placing anchored rafts in the ocean as resting platforms for walruses.

"No one on Earth is immune to Arctic warming."

Melting ice in the Arctic allowed a gas tanker to sail through the Northern Sea Route in the middle of winter

Canada is not a proud northern nation. Its Arctic is undefended, undeveloped and socially fraught.

Every week, hundreds of flights on U.S. airlines pass through Russian airspace. Only a handful of these flights actually start or end in Russia. Most are between the U.S. and Asia or the Middle East, for which the fastest routes necessitate flying over the Arctic and across Russia’s vast Siberian tundra. The Russian Arctic and […]

Global Warming and the Gulf Stream

Average temperatures in Dikson were more than 5°C above normal this summer.

Arctic coasts are increasingly affected by erosion and flooding, owing to decreasing sea ice, thawing permafrost and rising sea levels. This Review examines the changes in Arctic coastal morphodynamics and discusses the broader impacts on Arctic systems.

Threats to walruses in the Arctic are in the spotlight again, as six environmental and conservation groups have filed a lawsuit against the U.S. Fish and Wildlife Service (FWS) challenging a rule that would allow oil companies to begin drilling in key walrus feeding areas in the Arctic’s Chukchi Sea by next year. Shell has […]

"It can burn, and burn, and burn."

Sea ice fell to its lowest extent on record for this time of year, while new studies find Arctic coastal ice may be receding 70-110% faster than thought, winter ice is failing to regrow fully, and last multi-year ice refuge is under assault.

Norway deploys radiation drones along its coast amidst nuclear emergency concernsFive Coast Guard ships are soon to carry drones with sensors capable of detecting radioactivity in case of a maritim…

The berg covers 1,270 sq km - nearly 490 square miles - but its break-off was expected.

Neil Swart never thought the data he collected in the Antarctic Ocean 13 years ago would lead to such a critical conclusion.

Temperatures are now so high at the north pole that scientists are contemplating radical schemes to avoid catastrophe

Several methane domes, some 500m wide, have been mapped on the Arctic Ocean floor. They may be signs of soon-to-happen methane expulsions that have previously created massive craters in a near-by area.

An ice cap in the high Arctic has lost what British scientists say is a significant amount of ice in an unusually short time. Ice caps and glaciers such as this one in Svalbard account for about a third of recent global sea level rise. Photo credit: Woodwalker via Wikimedia Commons It has thinned by […]

Satellite imagery shows hundreds of glaciers shrinking as average annual temperature rises 3.6C in 70 years

Methane sources and sinks in the Arctic are poorly quantified. In particular, methane emissions from the Arctic Ocean and the potential sink capacity are still under debate. In this context sea ice impact on and the intense cycling of methane between sea ice and Polar surface water (PSW) becomes pivotal. We report on methane super- and under-saturation in PSW in the Eurasian Basin (EB), strongly linked to sea ice-ocean interactions. In the southern EB under-saturation in PSW is caused by both inflow of warm Atlantic water and short-time contact with sea ice. By comparison in the northern EB long-time sea ice-PSW contact triggered by freezing and melting events induces a methane excess. We reveal the Ttranspolar Drift Stream as crucial for methane transport and show that inter-annual shifts in sea ice drift patterns generate inter-annually patchy methane excess in PSW. Using backward trajectories combined with δ18O signatures of sea ice cores we determine the sea ice source regions to be in the Laptev Sea Polynyas and the off shelf regime in 2011 and 2015, respectively. We denote the Transpolar Drift regime as decisive for the fate of methane released on the Siberian shelves.

The British Antarctic Survey is pulling all staff out of the space-age Halley base in March because of a big crack in nearby ice.

Putin is calling the arctic a "top defense priority."

Degradation of the subsea permafrost in the East Siberian Arctic Shelf causing massive methane release - Natalia Shakhova interview

On the right summer day, a person can watch a massive lake disappear in a few hours, thanks to warming temperatures that increase the fissures in the ice.

Research suggests climate change is going to cause more damage to roads and other infrastructure in Canada's North than previously feared. The study has major implications for construction in the North.

A new international report shows that Arctic temperatures are rising higher and faster than expected, and the effects are already being felt around the world.

All of Moscow’s effort and attention, combined with Canada's neglect, has effectively turned the Arctic Ocean into Putin’s Lake.
