It's a rare sight in Vancouver's False Creek, but a pod of orcas was spotted swimming the city's most inner waterway on Wednesday.

The jury is still out on exactly what the cause is, but the unusually-coloured calf spotted near Nanaimo on Tuesday is already making waves.

It lost more than 40 per cent of its area in just two days at the end of July, researchers said on Thursday.

I've asked quite a few of the elders here if they had ever seen and none of them said they had ever seen it, said Skidegate Chief Councillor Bill Yovanovich, who took the photos Saturday on Lina Island. They show small bits of white shells arranged into what appears to be an intentional grid pattern that stretches at least a hundred metres along the beach.

Footage shot across the North Atlantic captured a stunning view of accumulating sea ice over Brighton, Newfoundland, but, according to researchers, also serves as stark reminder of the impact of climate change.

Up to 10 sperm whales have been stranded between Withernsea and Tunstall on the coast. Members of the coastguard and British Divers Marine Life Rescue (BDMLR) are on the beach, between Tunstall and Withernsea, near Hull.

A winter storm combined with a 20.7-foot high tide hammered the north shore of Kachemak Bay last Thursday.

Another Metro Vancouver beach has been closed to swimmers following concerns about bacteria.

A red tide bloom was found in multiple areas of coastal Collier County. Individuals with chronic respiratory problems should be cautious and stay away from this location, as red tide can affect breathing. Residents near the beaches are encouraged to close windows and run the air conditioners.

Thousands of Atlantic salmon have escaped into Pacific waters east of Victoria after a net pen was damaged. The company is blaming high tides, but the tides weren't unusual.

Large holes had developed by mid-August in the low-concentration ice in the Chukchi and Beaufort seas, according to National Snow and Ice Data Center.

Shorter periods of sea ice on Hudson Bay as a result of climate change translate into fewer polar bears in Churchill region.

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.
