Human-induced climate change “contributed substantially” to the atmospheric river and ensuing floods that devastated B.C. last year, a new study by Environment Canada scientists confirms, warning Canadians to brace for more of the same. “The chance this kind of flood will happen has increased by 100 to 300 per cent due to human influence,” Xuebin Zhang, a senior research scientist with Environment and Climate Change Canada, told Canada’s National Observer.
Tree planting can reduce flood risk, say wildlife and watershed groups
Simon Mitchell of the World Wildlife Fund and Natalie Deseta of the Nashwaak Watershed Association say planting trees, shrubs and grasses along the river and its tributaries can help reduce the risk of bad flooding in spring and from extreme rain events. "When we're thinking about flooding," said Mitchell, "our biggest issue is the frequency and intensity at which these events come." Mitchell is a habitat specialist who studies the St. John River and a vice president with the Canadian WWF based in the Nackawic area.
