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.
Much of Alberta and Saskatchewan relies on water from melting snow in the Rocky Mountains for replenishment of waterways in the summer. But John Pomeroy — director of the University of Saskatchewan's Coldwater Laboratory in Canmore, Alta. — told CBC that this past winter provided one of the lowest snowpacks he's seen. The snow also melted about six weeks earlier than anticipated, fuelled by the unseasonably warm weather.
Snow-wise, it hasn't been a great year in the Rocky Mountains, says Canmore-based water expert John Pomeroy. "[The snowpack] is in the lowest quarter to lowest 10 per cent of all years measured over the last half century in the Kananaskis-Banff region," said Pomeroy, who is Canada Research Chair in Water Resources and Climate Change at the University of Saskatchewan. "It's definitely a low snow year."
This winter brought a healthy snowpack to many mountain peaks in North America. California experienced record snow, at times burying communities and ski hills and in Canada, skiers and snowboarders enjoyed the powder this season, with British Columbia experiencing a flush of late-season snow putting snowpacks right around normal. But despite this snowy winter in the mountains, climate change is taking its toll on our slopes.
Virtually every snowflake that falls on Fortress Mountain in the Kananaskis region is recorded and watched. "We're in a time when we get extreme weather and a changing climate," said John Pomeroy, director of the University of Saskatchewan's Centre for Hydrology. "We try to follow every drop of water, every flake of snow, and see where it's going." The Centre for Hydrology's Coldwater laboratory is made up of stations with instruments placed on the ridges, glaciers, valleys, and creeks in the Alberta Rockies.
The United Nations General Assembly has adopted a resolution to declare 2025 the International Year of Glaciers' Preservation — a concept Coldwater Lab director John Pomeroy says is rooted close to home in Canmore, Alta. The declaration is something researchers in Canada hope will help wake up the world that it needs to change course. More than symbolic, it's a year when scientists will release findings and share climate models and projections linked to the disappearance of glaciers, and conferences will raise the profile of this issue.
John Pomeroy, director of the Global Water Futures program at the University of Saskatchewan is delivering virtual talks on glacier preservation and water issues in the circumpolar North to delegates at the COP27 climate summit. He spoke with Postmedia ahead of his second lecture, set to be delivered Wednesday. Q: What are some key points from your talks? A: Warming is proceeding faster in the mountains than other parts of the world. Glaciers are retreating, snowpacks are melting earlier in the year. We’re also getting extremely high temperatures, such as in 2021, and massive forest fires in areas as well as flash-flooding coming form heavy rainfall at times. All these are occurring at once, which is making it very challenging.
A Canadian professor is warning many of the iconic glaciers in the Canadian Rockies will be gone in the coming decades due to climate change. John Pomeroy is the Canada research chair in water resources and climate change at the University of Saskatchewan. He says the state of the glaciers in the Canadian Rockies is "dire right now." "We've lost hundreds of them already, just over the last few decades, and we'll be losing most of the rest over this century - including over most peoples' lifetimes."
Farmers and other producers in southwest Saskatchewan are experiencing dry fall weather. The lack of rain in some areas is causing "moderate to severe on-site water shortages," according to the latest provincial crop report. "It's just setting us up again for a questionable start for next spring," Garner Deobald, the president of the Saskatchewan Stock Growers Association, said. Deobald said most places have seen below average snowfall for the last three or four years. He said the Ministry of Agriculture needs to monitor water quality.
Four research centres at the University of Saskatchewan are getting nearly $170 million in funding, and the work done at one centre is necessary for understanding and addressing a water crisis in Canada, its director says. "Water problems we are facing in Canada seems to be getting more severe. Costs of droughts and floods have reached about $40 billion since the turn of the century. It was just one or two billion before that in Canadian history," John Pomeroy, director at Global Water Futures Observatories, said in an interview.
Days after a glacier collapse in the Italian Alps, search and rescue teams are still finding victims. On Wednesday, Reuters reported the death count had risen to nine after the bodies of two more people were found. Three are still missing, with several more injured in the disaster. Italy's prime minister linked the tragedy to environmental factors as parts of the country experienced record-breaking temperatures during a summer heat wave.
A drive through the Canadian Rockies will treat you to views of blue mountain lakes, wildlife and, of course, glaciers. But with our changing climate and warming winters, glaciers are receding at an alarming rate in Canada and around the world. Globally that will impact sea levels while here on the Prairies, the loss of our Rocky Mountain glaciers will affect our freshwater supply. “We’re past the tipping point for the glaciers in the Canadian Rockies,” says John Pomeroy, professor and Canada Research Chair in water resources and climate change at the University of Saskatchewan.
If it seems like the water level on the Bow River is lower than normal this winter, you're right, and the possible implications could be serious, says a top water scientist. The Bow River's flow level is in the lowest quarter of all observations in the 125 years that the Water Survey of Canada has measured the river, according to researcher John Pomeroy, who is based in Canmore, Alta. He is the Canada Research Chair in Water Resources and Climate Change at the University of Saskatchewan.
Drought is impacting the agriculture sector across Canada but the brunt of the dry weather is being felt in Manitoba and Saskatchewan, where moisture levels have been low since last fall. Moisture levels have improved in B.C. and Alberta, where there’s been more precipitation and snowpack. Ontario has received about half of the precipitation expected at this time of the year.
Alberta's plan to allow for open-pit coal mining in the Rocky Mountains could be a serious threat to Saskatchewan's water supply, says the director of the Global Water Futures Project at the University of Saskatchewan. "For a water scientist to see this happening, it's just an abomination to have these types of developments suggested in the headwaters of the rivers that supply drinking water and the economy for most of Saskatchewan," John Pomeroy told CBC's Blue Sky. Last spring, the Alberta government revoked a 1976 policy that blocked open-pit coal mining on the eastern slopes and peaks of the Rockies.
Spotty research and inconsistent monitoring have made it impossible to evaluate the health of most Canadian watersheds, a study has found. “It’s still largely unknown,” said Elizabeth Hendricks of the World Wildlife Fund, which has just released its second evaluation of the condition of Canada’s freshwater environments. Hendricks said the report points to the need for standardized, national water monitoring done by local communities.
A new University of Saskatchewan smartphone app will help farmers and communities identify hotspots of nutrient contamination in freshwaters and possibly predict where algae blooms — slimy, plant-like green organisms that hinder water quality — are likely to grow. “Tracking how and where agricultural nutrients, which help crops grow, may be washed away with rainfalls and snowmelt is a major concern for both researchers and the public, and that’s where our app comes in,” said Environment and Climate Change Canada scientist Diogo Costa.
