On August 14, 2021, temperatures rose above freezing on the summit of Greenland, fueling a rain event that dumped 7 billion tons of water—the heaviest since records began in 1950.

Entomologists confirm the report of the world's largest hornet — a worrisome invasive species that originates from East Asia and Japan — by a person in a rural area near the Canadian border.

These prolonged above-normal temperatures required the City of Cranbrook to increase water restrictions to levels not generally experienced by the community. Additionally, during this time (personal experience), the water was discoloured and had an odor, forcing bottled water to ensure safe drinking.

A handful of fires burning east of Humboldt continued to grow overnight with minimal containment, bringing air quality and travel impacts. Parts of State Route 36 have reopened to controlled traffic. Overall hot, dry conditions are expected to complicate fire suppression efforts.

A decades-long decline in salmon in the Yukon River has reached a crisis this year, forcing harvest closures and prompting emergency shipments of salmon from other regions of Alaska to river residents who are otherwise facing food shortages.

The wildfire has now grown to 565 square kilometres in size.

The village is losing ground three times faster than it was 10 years ago, according to studies of Napakiak’s erosion. During high tide, the river is only 64 feet from the high-schoolers’ original classroom and gets closer by the day.

At this time of year, the geese are moulting — and therefore unable to fly — so they congregate near ponds to avoid the Arctic fox (Vulpes lagopus), which is reluctant to jump into the water.

Poaching and climate change might be the reasons why more than 1,200 migrating animals did not make it across the wide Arctic waterway.

Unusual high water all summer in Noatak, causing massive erosion towards the airport and old buried landfill, exposing old trash into the river.

Red currant leaf consumption by something was observed by my supervisor while walking along a salmon stream.

About 10% of our catch during dip net fishing at mouth of Kenai River was harboring these worms.

Parts of Interior and Southcentral Alaska will see poor air quality as a result of wildfires this week, the Alaska Department of Environmental Conservation warned on Tuesday.
