There has been little snowfall, temperatures are above normal and there is little to no sea ice on Alaska's northern coasts.

NOAA Fisheries' summer trawl survey shows Norton Sound red king crab are moving, Arctic cod numbers have dropped significantly, and Pacific cod are continuing to increase as the Northern Bering Sea ecosystem undergoes drastic change.

Japan's magnificent great purple emperor butterfly is at risk of dying out, a nationwide research pr

As sea ice in the Arctic decreases due to climate change, it’s opening the way for more than cruise ship travel. Scientists have found evidence that links the decline of sea ice to the emergence of a virus in Arctic marine mammals that has killed thousands of seals in European waters.

When scientists found that Alaska sea otters were exposed to a sometimes-deadly virus that plagues seals in the North Atlantic, they were puzzled. Phocine distemper virus had not been previously found in Alaska waters.

The fast-warming Sea of Okhotsk, wedged between Russia and Japan, is a cautionary tale of the far-reaching consequences when climate dominoes begin to fall.

For half a century, Taku had been the one known Alaskan glacier to withstand the effects of climate change – until now.

Thanks to stricter pollution laws, toxin levels have been dropping steadily in the Baltic. Concentrations of environmental toxins have dropped by as much as 80 percent.

In just a few years, 8 million native angasi oyster hatchlings have been placed in the waters off Victoria, South Australia, Queensland and Western Australia, on the recycled mollusc shells collected from restaurants. They've turned empty, sandy seabeds into thriving ecosystems.

When sea otters in Alaska were diagnosed with phocine distemper virus (PDV) in 2004, scientists were confused. The pathogen in the Morbillivirus genus that contains viruses like measles had then only been found in Europe and on the eastern coast of North America.

Regulations have lowered mercury emissions globally, but the risks to ocean ecosystems and human health may be getting worse.

As we rolled into November, scientists discovered last month was the warmest October on record globally.

The grey seal population has grown by an average of five percent annually since the turn of the millennium.

The animal die-offs offer the world a stark example of the perils of rising ocean temperatures, which already are upending parts of the Bering Sea ecosystem.

As wholesale prices skyrocket for Pacific flying squid amid a record low catch in Japan, processing companies in the "squid town" of Hakodate, Hokkaido, ar

Scientists devised a better way to calculate land elevations and their findings are dire: Far more cities will be inundated by climate change than previously thought.

Chukotka officials propose to classify polar bear sightings in populated areas as emergencies to mobilize resources for managing these situations.

Conservation groups are calling for the immediate closure of the herring fishery in the Strait of Georgia following the release of new federal government data showing a four-year population biomass decline of almost 60 per cent. “We’ve been systematically overfishing these stocks and the Gulf of Georgia fishery is the last one left,” Pacific Wild...
