When Hurricane Irma ravaged the Caribbean island of Barbuda, the storm left it uninhabitable." And, now, for the first time in 300 years, no one lives there.

HEALY, ALASKA—Bitter winters still dominate life in the Alaskan interior, but a practiced eye can spot the signs of a warming climate, particularly in the ground. Beneath the rolling fields of tussock scattered just north of the Alaska Range, what was once permanently frozen is starting to thaw. The impacts could ripple across the planet.

Record numbers of the potentially-fatal Portuguese man o' war have washed up on the Cornish coast, according to conservationists.

Atlantic salmon, believed to be part of a cohort that escaped from a U.S.-based fish farm on Aug. 19, are being hauled in by anglers fishing out of French Creek on mid-Vancouver Island. Cameron Whe…

A new study of the marine invertebrates living in the seas around Antarctica reveals there will be more 'losers' than 'winners' over the next century as the Antarctic seafloor warms. The results are published in the journal Nature Climate Change this week.

For centuries, marine species have moved around either by hitching ride on the hulls of ships or as stowaways in ballast water. In many instances, species have been deliberately introduced for aquaculture or other commercial purposes.

It's unclear how many Atlantic salmon escaped from the pen. The Lummi Nation says tribal fishermen have removed 20,000 from the Puget Sound. Washington state officials says Cooke Aquaculture has recovered 120,000 fish from the pen and that more are still inside.

Several factors have conspired to make Hurricane Harvey so destructive in Texas, and warming temperatures are likely part of the problem.

Study calculates energy Harvey took from the ocean, shows human role.

The £234 million ($300 million) Christophe de Margerie (pictured) completed the journey from Hammerfest in Norway to Boryeong in South Korea in just 19 days.

The remnants of Harvey re-intensified into a hurricane on Thursday, and it may become a major hurricane by Friday.

Biologist Jackie Hilderling says four years of decline in B.C.'s sea star population is due to climate change warming local waters and making the animals susceptible to sea star-associated densovirus.

Officials blame the failure of a pen near Washington's Cypress Island on high tides caused by the eclipse, but that is being questioned. Fishing boats are scrambling to catch as many as possible.

A fish farm was destroyed after the Atlantic salmon escape, with Cooke Aquaculture calling it a “salvage operation.” Scientists debunked the statement from Cooke that “exceptionally high tides and currents coinciding with this week’s solar eclipse” caused the damage.

Local Indigenous community says the invasive species could devastate fishing industry in the area

New footage released to DeSmog Canada shows deformed and disfigured salmon at two salmon farms on the B.C. coast — just as British Columbia reels from news of the escape of up to 305,000 Atlantic farmed salmon from a Washington salmon pen. Wild salmon advocate and fisheries biologist Alexandra Morton said she was shocked by the footage. “I was shocked and frankly disgusted,” Morton told DeSmog Canada. “These fish have open sores, sea lice, blisters all over their skin and a disturbing number of them are going blind.” Morton said the footage also gives an indication of what is now travelling through Pacific waters after the escape of potentially hundreds of thousands of farmed Atlantic salmon in the San Juan Islands just east of Victoria. Atlantic salmon are considered invasive in Pacific waters.

Did Monday's eclipse play a role in a huge Atlantic salmon spill from a fish farm in the San Juans? The company says yes. The Washington Department of Fish and Wildlife is urging the public to catch as many of the fish as possible, with no limit on size or number. The fish are about 10 pounds each. No one will know how many escaped until harvesting is completed.
