Scientists have said the algae is spreading faster than anything they have seen in the remote Northwestern Hawaiian Islands.

Towering crags and peaks of the Canadian Rocky Mountains have been getting steadily greener over the past century, according to a new study.

New study spotlights influenza virus that could wreak havoc if it adapts to humans.

Wild salmon have higher rates of the parasites when ocean fish farms are near, research shows

Climate change leads to longer growing seasons in the Arctic. A new study shows that predators like wolf spiders respond to the changing conditions and have been able to produce two clutches of offspring during the short Arctic summer. The greater number of spiders may influence the food chains in Greenland.

A group advocating for the conservation of wild Atlantic salmon says the number of adult salmon returning to North America rivers fell to near historic lows last year.

The world’s biggest reindeer population is up for big vaccination as regional authorities in the Yamal-Nenets Autonomous Okrug act to stave off outbreaks of anthrax.

Scientists discover Arctic wolf spiders are doubling their egg production due to warmer weather. At the Zackenberg Research Station in Greenland, the scientists observed wolf spider populations in the area between 1996 and 2014 and noticed the arachnids were laying many more eggs as the Arctic experienced warmer weather.

May 2020 was the hottest May on record, reported the Copernicus Climate Change Service on June 5. Their data shows that globally, last month was 0.63 C warmer than the average May from 1981-2010.

Jan Egil Bakkeby had to flee for his life when he suddenly heard it start to crack in the cabin. Soon after, he witnessed the entire building being washed up on water.

Scientists thought it was dead. But it’s heating water faster than the global average.

New temperature maps for the endless stretches of Russian Arctic lands bear witness of unprecedented warming.

Melting permafrost, land erosion, and heavy rains are causing these villages to flood and sink

It was a remarkably cold winter across the high Arctic, at least compared to the abnormally mild winters in many recent years, but the weather pattern has reversed this spring.

Winters are getting shorter and summers are getting longer, a new comparison shows. In most regions of the U.S. and Canada, summer is about 6-10% longer and winter is about 7-11% shorter. In Alaska, winters are about 30% shorter than they were just a lifetime ago.

Biologists have to figure out how to monitor salmon populations in rural communities without the danger of bringing the coronavirus into those communities.

Soil organic carbon (SOC) stored in permafrost across the high-latitude/altitude Northern Hemisphere represents an important potential carbon source under future warming. Here, we provide a comprehensive investigation on the spatiotemporal dynamics of SOC over the high-altitude Tibetan Plateau (TP), which has received less attention compared with the circum-Arctic region. The permafrost region covers ~42% of the entire TP and contains ~37.21 Pg perennially frozen SOC at the baseline period (2006–2015). With continuous warming, the active layer is projected to further deepen, resulting in ~1.86 ± 0.49 Pg and ~3.80 ± 0.76 Pg permafrost carbon thawing by 2100 under moderate and high representative concentration pathways (RCP4.5 and RCP8.5), respectively. This could largely offset the regional carbon sink and even potentially turn the region into a net carbon source. Our findings also highlight the importance of deep permafrost thawing that is generally ignored in current Earth system models.

Unhealthful air quality is plaguing the region.

A new scientific study published Monday found that global warming is fueling a destructive algal bloom that is disrupting fisheries in the Arabian sea.

How the beavers got to the Baldwin Peninsula, which is surrounded by salt water and extends north of the Arctic Circle, is anyone’s guess.
