Highly venomous spiders native to Chile remain a worry for workers at a firm in Sandviken, near Gävle, several years after they were first discovered.

Engineers caution that residents wanting to clear their own roofs face greater risk of hurting themselves or damaging roofs than from a collapse.

Researchers found that the seismic waves get amplified as they bounce back and forth off the sides and bottom of the sedimentary basin near Minto. So people in the flats perceive the earthquakes as bigger than they actually are and it’s all about the reverberation.

Ice lies thick on the Yenisey River as nuclear-powered icebreaker "Sibir" escorts a cargo ship to the remote terminal applied by oil company Rosneft

There’s an old saying that captures the essence of subsistence harvesting: “When the tide is out, the table is set.” Clams, mussels and other food are available for the person. Climate change has impacted subsistence in the ocean and on the land. Community members share observations on changes.

Russian and American scientists have been cut off from collaborating for a year, and Arctic research is suffering.

Old Tjikko is 9500 years old, one of the oldest fir tree in the world.

The petition is the latest step in a long effort to better protect oil spill responders from a range of long- and short-term health problems suffered after BP’s Deepwater Horizon oil disaster in 2010 and other spills.

A new report predicts there will be almost no narwhal left in an area off the northeastern coast of Baffin Island this summer and says shipping traffic from the nearby Mary River iron ore mine is to blame. The mine's operator says it leaves out key information.

Trudeau orders takedown of unidentified object in Canada airspace.

The pack killed all the black-tailed deer on the island and another established pack back on the mainland was preventing their return. Scientists assumed they would die off from starvation.

Researchers at Memorial University, Ocean Networks Canada and the University of Victoria found the urchins, living as deep as 400 metres below, were expanding their populations into shallower water at an average rate of 3.5 metres per year as ocean warming reduces oxygen levels and food sources at lower depths.

The huge sea stars, which help conserve kelp beds by eating sea urchins, have been devastated by a wasting disease that is linked by scientists to climate change.

A polar bear that killed a young mother and her baby last month in western Alaska was likely an older animal in poor physical condition.

In coming decades, the ocean conditions that triggered the snow crab crash and harvest closure are expected to be common.

Atmospheric rivers, those long, powerful streams of moisture in the sky, are becoming more frequent in the Arctic, and they’re helping to drive dramatic shrinking of the Arctic’s sea ice cover.

Harmful algal blooms will become a more common feature of a warming Arctic. Last summer, a massive bloom was detected off the coast of Western Alaska, almost by chance, when scientists sailing through the Bering Strait and Chukchi Sea found worryingly high levels of Alexandrium catenella.

Research shows Beavers are relatively new to the Seward Peninsula and push farther north as climate change occurs.

We (Norway) need to build solar power, at a pace we have not seen before, according to the Energy Commission. And the industry believes a 33-fold increase in seven years is realistic.

East Finnmark region was 4 to 5 degrees warmer than normal in January.
