A new study links rapid deoxygenation in the Gulf of St. Lawrence to two powerful currents: the Gulf Stream and the Labrador Current.

Commercial salmon fisheries in Washington, Oregon, and California are eligible for a portion of $20 million in disaster assistance after federal officials determined fishery failures occurred.

For millennia, ecosystems in Greenland and throughout the Arctic have been regulated by seasonal changes that govern the greening of vegetation and the migration and reproduction of animals. But a rapidly warming climate and disappearing sea ice are upending that finely tuned balance.

Mass die-offs and breeding failures, now ongoing for years, have marine biologists worried that this is a new normal caused by climate change.

From Longyearbyen to Kiribati, Bangladesh and California. Author Teresa Grøtan has collected young people's everyday life with climate change in the book "Before the Island Sink."

'Shocking' decline of Arctic skua revealed in study. Conservation scientists say a lack of food is behind the drop in the UK population.

The Western New York landscape is now strewn with dead and dying Ash trees. The evidence of the Ash Borer's destruction is crystal clear, and our environment may never be the same.

ALBANY - After years of trying to slow a voracious Chinese beetle that is decimating ash trees, state environmental officials are waving the white flag: The Department of Environmental Conservation dropped a logging quarantine, and said it might be time to cut healthy trees still uninfested. In a brief notice posted online Wednesday, the DEC repealed logging restrictions that had failed to contain the spread of the emerald ash borer (EAB) by limiting shipments of ash. The state created the quarantine in 2015 to slow the insect, which is a shiny green beetle about the size of a penny. The borer likely will ultimately bring about the end of the state's 700 million ash trees - down from earlier estimates of 900 million ash trees before the beetles' arrival - and forever change an industry that uses ash to produce bats for major league baseball.

An increase in carbon emissions are showing up not only in the air, but also in water. Now researchers and shellfish farmers are teaming up to see how marine plants can help stave off the effects of ocean acidification. Special correspondent Jes Burns of Oregon Public Broadcasting reports.

Creamy jasmine wildflowers once common in the Colorado high country may be vanishing as climate change brings warmer and drier conditions.

On a remote Alaskan sandbar, under the watchful eye of a devoted scientist for more than four decades, climate change is forcing a colony of seabirds into a real-time race: evolve or go extinct.

Only 1,123 adult winter Chinook salmon, once one of the biggest salmon runs on the Sacramento River and its tributaries, returned to the Sacramento Valley in 2017, according to a report sent to the Pacific Fishery Management Council (PFMC) by the...

Habitat of the endangered Vancouver Island marmot is disappearing as the warming climate allows trees to grow higher up mountainsides, turning alpine meadows into forest. Adam Taylor, executive . . .

Climate change has warmed the waters east of Tasmania at four times the speed of the global average. But the heatwave of the southern summer of 2015/2016 was something exceptional, damaging fisheries and bringing new species to the island. It's a sign of things to come, say the researchers examining these events.

Keeping tabs on capelin — from the shores of the Atlantic ocean to the world wide web.

An assistant professor at the University of Alaska–Fairbanks suspects that changes seen in the auklet population on Little Diomede may be related to changes in climate.

Since June 7, 2017, elevated North Atlantic right whale (Eubalaena glacialis) mortalities have been documented, primarily in Canada and were declared an Unusual Mortality Event.  In 2017, there was a total of 17 confirmed dead stranded whales (12 in Canada; 5 in the United States) and in 2018, three whales stranded in the United States. In 2019, two whales have stranded in Canada.

The whales seem to have died from starvation and washed up on shore from California to Alaska

These big, blubbery beasts are sensitive souls that dislike being disturbed by people. Unfortunately for them, warming Arctic temperatures are bringing more shipping and tourism to their home waters.

Guyana’s fish production has suffered a significant decline partly due to the adverse impact of sargassum seaweed, local and regional fishery experts said.
