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.
