A deadly wildfire burned more than 2,000 buildings in the Hawaiian town of Lahaina on Maui in August and left behind piles of toxic debris.

As ocean temperatures trend warmer than average, green crab larvae dispersed in ocean currents from more southern latitudes will find more suitable habitat along the Alaska coast. Recently, adult green crabs have been detected in Skidegate Inlet on Haida Gwaii, British Columbia, and larval crabs have been found in Prince Rupert, both less than 100 miles south of Ketchikan.

The seabirds are struggling because of climate-linked ecosystem shifts — which can affect the supply and the timing of available food — as well as a harmful algal bloom and a viral outbreak in the region, she said. And their peril jeopardizes the human communities, as well: "Birds are essential to our region — they are nutritionally and economically essential," said Sheffield.

Scientists determine geese died due to exhaustion and salt-poisoning. More birds end up dying because of the long flights they undertake, in extreme conditions.

Special report: Ocean warming has put at risk the historic Alaska crab fishery. After a dismal summer survey, state biologists slashed this year’s harvest of snow crab by nearly 90% from 2021 levels.

It causes legs to fall off and, ultimately, results in disintegration of the animals’ bodies. Climate change may be behind that disease, as the arrival of Pacific marine heat waves coincided with the disease outbreak, according to federal biologists.The sea star, with a range from Baja California to the Aleutians, would be the first sea star with an Endangered Species Act listing.

The chief of the U.N. nuclear agency will visit Japan next week to meet with officials and see final preparations for the release of treated radioactive wastewater from the damaged Fukushima nuclear plant into the Pacific Ocean.

The company says it's the first in the world to convert a full fleet to run on the most environmentally friendly fuel available.

Weakened wind patterns likely spurred the wave of extreme ocean heat that swept the North Pacific last summer, according to new research led by the University of Colorado Boulder and the Scripps Institution of Oceanography at the University of California San Diego. The marine heat wave, named the "Blob 2.0" after 2013's "Blob"; likely damaged marine ecosystems and hurt coastal fisheries. Waters off the U.S. West Coast were a record-breaking 4.5 degrees F (2.5 degrees C) above normal, the authors found.

Cars and houses submerged in water, commuters wading through buses knee-high in floods, and homeowners counting the cost of destroyed properties.

Researchers now are uncertain when and to what extent the ice may return, and have scrambled to better understand the consequences of back-to-back years of its loss.

State officials said that king salmon runs are not showing signs of improvement and that conservative measures are needed to ensure future fishing opportunities.

The endangered population continues to slip and calf numbers are few, but no single factor has been identified as the cause.

Twenty-two sea lions have been found dead on beaches in California, with many more found sick.

Researchers are predicting low fish runs in the Norton Sound and Northern Bering Sea region again next year, according to research biologist Jim Murphy.

Experts say a wasting disease epidemic has decimated about 95% of the sunflower sea star population from Alaska’s Aleutian Islands to Mexico’s Baja California peninsula. Without sea stars to keep them in check, sea urchins are causing a troubling decline in kelp forests that provide food and shelter.

The Arctic Encounter Symposium (AES) held its 2023 event, bringing together policymakers, industry leaders, military leaders and other experts to discuss the leading issues in Arctic policy, innovation and development. The event allowed attendees to hear from several Alaska Natives about their experiences in a rapidly changing climate and ecosystem.

The Northern Bering Sea showed signs of ecological recovery in 2023, with improved conditions for zooplankton and fish despite ongoing challenges from climate change and variable sea ice patterns.
