A new study that suggests sockeye returns have dropped by three-quarters in the Skeena River over the last century should serve as a "wake-up call" for B.C., the lead researcher says.

Homer-area neighborhoods have been told to prepare for potential evacuation. The Sterling and Parks highways have been partially reopened — but expect delays.

Usually by August, peak fire season has passed. But fire and climate experts say conditions in Southcentral Alaska were nearly perfect for fire this weekend, from the sky to the dry forest floor.

A fire management official said more concrete information about the structures damaged by the fire will be available after emergency managers go in to survey the area on Tuesday.

After a decade or so of only about 20 reported cases annually, 2018 saw 43 cases detected on cattle and pig farms.

“Whenever a seismic boat goes past and we drop our gear, the fish aren’t there. Any fisherman, or fisherman worth their salt, will tell you there’s an impact. They’ve seen it first-hand.”

One theory is the pinks were traveling somewhere else to spawn, and taking a longer than usual route to avoid warming water.

Halifax-based scuba diver Lloyd Bond says in the last three years he's seen increasing numbers of butterfly fish, seahorses, cornet fish, trigger fish, puffer fish, and many other species not native to Canadian waters.

From the Koyukuk River, to the Kuskokwim, to Norton Sound, to Bristol Bay’s Igushik River, unusually warm temperatures across Alaska this summer led to die-offs of unspawned chum, sockeye and pink salmon. Warm waters also sometimes this summer acted as a “thermal block” — essentially a wall of heat salmon don’t swim past, delaying upriver migration.

Islanders are struggling to reconcile impact of global warming with traditional way of life.

What caused roughly 60,000 dead murres to wash ashore in Alaska? The answer to this could be very important to the murre (or turr) populations in the Atlantic.

An increasing number of marine researchers say the voracious eaters are thriving at the expense of higher-value sockeye salmon, seabirds and other species with whom their diet overlaps.

Two separate pods of pilot whales have gotten beached on Icelandic shores this summer, RÚV reports, leading experts to apprise locals of how best they can respond to such situations. Marine biologist Edda Elísabet Magnúsdóttir says that such beachings are becoming a yearly occurrence – an indirect result of warming ocean temperatures – and likely […]

For example, when looking at water in some areas around St. Lawrence Island, from 2010 to 2017, the bottom temperature went up by eight degrees Celsius (about 14° Fahrenheit).

Stop land damage and change food production to halt climate crisis, United Nations scientists warn in second IPCC report

Somewhere between the size of a sewer rat and a beaver, with a tail resembling that of an opossum and protruding, nacho cheese-colored teeth, the nutria is both impressively unattractive and highly destructive.

Average temperature for month amid Arctic heatwave was 58.1F (14.5C), nearly 1F above previous high set in July 2004

These tiny, black, thread-like pests dig into plants and like to hang about in gangs, which is why you see so many of them. It is as if they want to be as annoying as possible.

More than a month’s worth of rain has soaked parts of the state in just a few days, setting records.
