(Phys.org)—A trio of researchers with the University of Regina and University of Western Ontario, both in Canada, has found that a history of drought in the areas that feed the Athabasca River indicates that droughts are likely in the future, perhaps putting oilsands mining in jeopardy. In their paper published in Proceedings of the National Academy of Sciences, David Sauchyn, Jeannine-Marie St-Jacques, and Brian Luckman describe their study of tree rings in the area and what doing so revealed about the history of rainfall there.
