Caused by eating fish that has not been properly chilled, symptoms can last up to 48 hours and include severe headaches, palpitations, blurred vision and abdominal cramps.At least seven people fell ill between May and August. Between 2015-2018, there were only five.

Bull trout, which are technically char, mostly inhabit cold and pristine snow-melt-fed waters. Changes in water quality and temperatures challenge the future for this species in Alberta.

The last time it was this cold was in 1916, with a low temperature of -0.6°C.”

As climate change opens new regions to mosquitoes, Nepal suffers an outbreak of the painful viral disease that has sickened more than 9,000 people.

With hibernation fast approaching, a grizzly bear family is spotted searching for fish near the shores of Canada's Knight Inlet. They're emaciated, and wildlife observers worry might not make it through winter. The heartbreaking images highlight another victim of the climate crisis and the depleted salmon population.

Northern Harvest Sea Farms is busy cleaning pens of dead salmon, and the province's head aquaculture vet says higher-than-average water temperatures are to blame.

Returning to port with tons of algae in their trammel nets, with hardly any fish, has become a common drama for the men fishing in Spain's Southern coast. The same “catastrophe” is also threatening the marine biodiversity of the area and piling up on beaches.

The number of chinook salmon that reached the Whitehorse fish ladder this year hit a 40-year low, and it's not clear why. Just 282 chinook passed through the fish ladder this year, compared to 690 last year. "We did see some large pre-spawn mortality die-offs in a tributary of the Yukon River — the Koyukuk in Alaska. This was for summer chum, and not chinook — but we expect that that higher water temperature also affected the chinook migrating through."

"To grow tomatoes you need eight hours of sunlight each day. Not a problem. But you also need 3-4 months of warm temperatures between 55 and 75 degrees Fahrenheit. That's the problem."

Scripps Oceanography says rapid heating was caused by fair, hot weather

A new marine heat wave spreading across a portion of the Pacific Ocean off the coast of British Columbia resembles the infamous "blob" that disrupted marine life five years ago. 

August 29th was the latest date ever recorded for an over-25-degree day in Finnish Lapland.

Robert Prescott, of the Wellfleet Bay Wildlife Sanctuary, believes a warming trend allowed the turtles to delay their migration south.

After frost comes spring, but when it happens in mid-November plants get confused. That is not good news.

The skin lesion in the photo is likely caused by a stress-related bacterial infection – possibly trauma initiated. Probably common opportunistic bacteria in the environment such as motile Pseudomonas/Aeromonas Gram-negative organisms.

Bundle up, sit by the fire and warm your hot chocolate before reading this. It's only November 12 and one spot in the country has already picked up four and a half feet of snow! And that lucky (or maybe unlucky) winner is...

For 300 years, glacial runoff was the major water source for Kluane Lake, flowing in by way of the Slims River. But in May 2016, Kluane Lake levels dropped precipitously. The problem was a case of "river piracy" — incredibly rare, and hugely significant. The terminus or end of the Kaskawulsh glacier had receded enough that a glacial lake that fed the Slims River suddenly drained when the glacier outflow found a new direction to a new river.

With Halloween just over a week out, Fairbanks is looking at the potential of a third straight year with minimal snow cover, and a possible first ever green Halloween.

The blob is the popular name for a huge patch of warm water that has reached above normal temperatures in the Pacific Ocean.

A meteorologist says unseasonably warm weather in B.C. is once again causing a large area of the Pacific Ocean to heat up considerably, emulating a phenomenon from past years known as the “blob.”
