For three days this month, 7 billion tonnes of rain fell across Greenland — the largest amount since records began in 1950. It’s also the first time since then that rain, not snow, fell on Greenland’s highest peak.

Hundreds of thousands of people have been left without power, after Storm Fiona hit Canada's coastline. Parts of three provinces experienced torrential rain and winds of up to 160km/h (99mph), with trees and powerlines felled and houses washed into the sea.

Unusual amounts of multiyear ice in the Laptev and Siberian Sea could lead to difficult summer navigation along parts of Russia’s Northern Sea Route this summer, says the country’s Arctic and Antarctic Research Institute.

'Unprecedented numbers' of pink salmon were seen in 2017 and the fish have been spotted again this year.

The peer-reviewed research published this week in the Public Library of Science suggests that 99% of the orcas studied had photographic evidence of skin lesions. Researchers evaluated photos from nearly 20,000 orca sightings from 2004 to 2016, finding that lesions — often gray patches and gray targets on the orcas' skin — generally became more prevalent over time.

The southern resident killer whales who returned to their traditional summer feeding grounds in the Salish Sea on Tuesday and Wednesday after a long absence have apparently left again, and although most of the members of J-, K- and L-Pods appeared to be healthy, at least one may be close to starvation.

Last summer while scoping for marine invasive species we found the invasive colonial tunicate, Didemnum vexillum also know as marine vomit.

This early in spring, the season usually only starts, but the weather patterns have been changing, and so has been the harvest time, Donovan said.

Researchers from the Coral Reef Ecology Lab at the Hawai'i Institute of Marine Biology documented the third global bleaching event as it occurred from 2014 to 2016 at the Hanauma Bay Nature Preserve (HBNP) on the island of O'ahu, Hawai'i. Their findings, published in the international journal PeerJ, show that temperature is by far the most influential factor in coral bleaching at this well-managed location where corals, fish, and all other organisms are protected.

New data show the population of baby lobsters off New England is below average, raising concerns about the size of future commercial hauls of the valuable crustaceans as waters warm.

The lobster population along the Norwegian coast is much worse off than first thought. New research shows a huge decline.

Summer commercial Dungeness crabbing was well below average in Lynn Canal, with fishermen hauling in an estimated 105,000 pounds this year compared

They are brightly coloured, beautiful and hungry — tropical fish and sea urchins are thriving in southern waters warmed by climate change. But now they are devastating kelp forests already knocked around by marine heatwaves.   

Gusts of up to 85mph were recorded in parts of Scotland as Storm Malik swept across the country.

Shellfish growers in Willapa Bay in southwest Washington, the self-styled "Oyster Capital of the World," are alarmed by an invasion of potentially destructive nonnative European green crabs. Some are asking for an all-out trapping offensive to corral the invasive species.

FISH production is being affected by climate change. Acting director of fisheries Nerissa Lucky said this was due to high sea water temperatures. CANARI technical officer Dr Ainka Granderson also said climate change posed a challenge for coastal communities in Trinidad and Tobago.Those communities are affected by the effects of extreme weather, coastal erosion, sea level rise, sargassum and coral bleaching.
