Kristen Villebrun and Wendy Bush hoped they wouldn't have to pray for Chedoke Creek, but four years after they first raised alarm about the water's condition, they were part of an Indigenous full moon ceremony to do just that. About 50 people showed up near Princess Point on the dark and frigid Monday evening for the monthly ceremony, which was particularly special as it focused on Chedoke Creek. The body of water that runs into Cootes Paradise had about 24 billion litres of sewage and storm water runoff leak into it due to a gate being left open.
The ocean shelf off Labrador has hit record high temperatures this summer, according to the federal Department of Fisheries and Oceans. St. John's-based DFO research scientist Frederic Cyr told CBC News the summer of 2023 has been "pretty incredible" for the world ocean. "The entire North Atlantic reached record high temperatures," said Cyr — although it's still generally colder than the rest of the ocean, he added.
A watershed group on P.E.I. hopes it will be smoother swimming for salmon returning to spawn this fall, thanks to a new pilot project run in partnership with the Canadian Wildlife and the Atlantic Salmon federations. The Souris and Area Branch of the P.E.I. Wildlife Federation is leading the project, which builds on work that's already been done in Western Canada while adapting it to the unique conditions in the province.
Kamloops is implementing stricter water use regulations amid worsening drought conditions in the Thompson River, a situation one conservationist says is putting salmon habitat at risk. The new water conservation measures the municipality in B.C.'s Interior is putting in place include a ban on water sprinklers for lawn irrigation. However, watering is still permitted with handheld spring-loaded nozzles.
The water temperature off southern Florida has been about 38 C two days in a row: that's as hot as a hot tub, as hot as the maximum recommended heat for a baby's bath, and hotter than what's usually recommended for a pregnant woman. It's also, meteorologists say, possibly the hottest seawater ever measured.
A rare and fatal flesh-eating bacteria is slowly creeping up the eastern U.S. coast, and some experts warn that it could eventually find its way into Canada if climate change continues to heat our oceans and lakes. The bacteria Vibrio vulnificus is usually found in subtropical regions, like the Gulf Coast (in states like Florida and Texas), which is home to warm waters with low salt content. But a recent study published on March 23 in the Scientific Reports journal said that over the last few decades, there has been an increase in the bacteria in northern locations near New Jersey and Delaware.
Decades of logging activities near rivers in B.C.'s Interior are driving up the temperatures of coho salmon habitats and threatening the species' survival, according to a new study. The study by Simon Fraser University and Fisheries and Oceans Canada (DFO), published last month in the Canadian Journal of Fisheries and Aquatic Sciences, looked into 28 tributaries of the North Thompson River watershed from Kamloops to Valemount.
Ocean temperatures off Nova Scotia hit record highs last summer, eclipsing the record-breaking temperatures set in the Atlantic a decade earlier. "It's pretty alarming," said Fisheries and Oceans Canada research scientist Chantelle Layton. Layton is part of the DFO team analyzing results from the annual Atlantic Ocean monitoring program in eastern Canada. Canadian scientists are discussing the 2022 data this week.
Last year was the hottest on record for the ocean, an upward trend only expected to continue as it wreaks havoc on coastal communities and spurs irreversible losses to marine ecosystems. Ocean warming has cascading effects, melting polar ice and causing sea-level rise, marine heat waves and ocean acidification, the United Nations’ panel of climate experts made clear on Monday. Sea-level rise has doubled in the last three decades, reaching a record high in 2021, the Intergovernmental Panel on Climate Change (IPCC) reported. Rising seas, coupled with more extreme weather, are setting the stage for a perfect storm of flooding for coastal communities.
Three watershed groups on P.E.I. are planting trees in beaver meadows this summer, part of a new project to help deal with the impacts of climate change. In the Souris area, trees are being planted in a beaver meadow that is part of the Naufrage River system, created when beavers abandoned a dam there decades ago. The local watershed co-ordinator said not all Islanders will know the term "beaver meadow" but they likely would have seen them.
A sweltering heat wave in much of Western Canada in the last week of June had cascading effects on sea life, experts say. Scott Hinch, director of the Pacific salmon ecology and conservation laboratory at the University of British Columbia, said juvenile salmon such as sockeye, coho and chinook in fresh water would have been most affected by recent heat waves. “They’re going to be living in fresh water for one to two years and it’s that life history stage, that this particular heat wave and just climate change in fresh water in particular, is going to have some of its greatest effects,” he said in an interview.
