Fed up with unpredictable winter storms cancelling air flights, closing highways and dumping enormous amounts of precipitation? Too bad. Canadian scientists say get used to it.
In a major forthcoming report on Canada's changing climate, scientists warn of everything from increased severe storm activity in Atlantic Canada to hotter summers and poorer air quality in urban Ontario. British Columbia may face retreating glaciers and snow loss on its mountains, causing potential water shortages. The Prairie provinces will continue to struggle with drought, impacting agriculture rurally and potentially causing water rationing in urban areas.
The 500-page report is the work of 145 leading Canadian scientists. They've examined the current and future risks climate change presents coast to coast and what they have to say isn't comforting.
Perhaps one of the people least surprised by the wicked weekend weather is Norm Catto, a geographer at Memorial University in Newfoundland, and one of the climate report's lead authors. He says the intensity of weather events is increasing. When Hurricane Juan swept through Atlantic Canada in 2003, the storm surge didn't coincide with high tide. But next time it could and the level of the water could be 40 to 50 centimetres higher. Quentin Chiotti, a senior scientist with Pollution Probe in Toronto and another study author, echoed Mr. Catto's concern. In Ontario, for example, intense dumps of precipitation could lead to floods of the sort Toronto and Peterborough endured in 2005.
