Dr. David Sauchyn is Research Professor at the Prairie Adaptation Research Collaborative (PARC) at the University of Regina. Dave’s main research interests are the climate and hydrology of the past millennium in Canada’s western interior and how knowledge of the past can inform scenarios of future climate and water supplies. He is Director of the University of Regina Tree-Ring Laboratory; Dave and his students have collected old wood from across the western boreal and montane forests for the reconstruction of western Canada’s climate and hydrology. Dave is a co-investigator in a five-year multi-disciplinary study of adaptation to climate change in northern Chile and the Canadian plains. He participated in the expert review of the Fourth Assessment Report of the Intergovernmental Panel on Climate Change and was a lead author of the Canada’s National Assessment of Climate Change released in March 2008. Dave has been an invited expert witness on climate change in the Canadian Senate and House of Commons, and at forums hosted by provincial premiers and environment ministers.
