Melting glaciers will be a big problem, if indeed they aren’t already. An agreement between Switzerland and Italy used a glacier to define their border and it has retreated so much that part of Italy has now moved into Switzerland, taking a restaurant with it into the new jurisdiction. I read also of the shrinking Haig glacier between British Columbia and Alberta, retreating rapidly. This has led to a river changing course, away from B.C. and towards Calgary—a city very happy to get more water in late summer droughts. I was amused to read of a local expert Shawn Marshall, an ice ages and climate dynamics expert and geography professor at the University of Calgary. Given that ash from local forest fires blackens the surface of the glacier and enables it to warm faster it amused me when Shawn told CBC News "There's a lot to cry about," he said, adding the glacier's like an old friend. "It's where they'll scatter my ashes someday."
