Water reservoirs created by damming rivers could have significant impacts on the world’s carbon cycle and climate system that aren’t being accounted for, a new study concludes.
The study, conducted by researchers at the University of Waterloo and the Université libre de Bruxelles, appears in Nature Communications. If found that man-made dam reservoirs trap nearly one-fifth of the organic carbon moving from land to ocean via the world’s rivers.
Just as many teenagers use cannabis every day as smoke cigarettes, according to a new report from the Propel Centre for Population Health Impact at the University of Waterloo.
The report, published yesterday as a supplement to Tobacco Use in Canada: Patterns and Trends, found that two per cent of Canadian students in Grades 7 to 12 – equivalent to more than 43,000 students – use marijuana every day. Daily smoking is similar at 1.8 per cent, according to the Canadian Student Tobacco, Alcohol and Drugs Survey.

Researchers at the Interdisciplinary Centre on Climate Change and the Partners for Action research network at the University of Waterloo surveyed 2,300 homeowners who live in communities that the Government of Canada’s Flood Damage Reduction Program designated as flood-risk areas.
