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.
Severe spike in COVID-19 detected in Saskatoon wastewater
The COVID-19 viral load in Saskatoon's wastewater spiked by more than 400 per cent in one week, according to research from the University of Saskatchewan. Researchers from the university's Global Water Futures program have been analyzing wastewater samples from Saskatoon, North Battleford and Prince Albert for COVID-19 since summer 2020. The results can predict a rise or fall of COVID-19 diagnoses about a week in advance. Researchers say most people start shedding SARS-CoV-2, the virus that causes COVID-19, within 24 hours of being infected.
