Book Description
The Palliser Triangle of south-west Saskatchewan and south-east Alberta is characterized by a variable climate, strong annual moisture deficit, and recurrent drought. Geomorphic systems in such environments are often sensitive to even minor changes in climate. This report considers four geomorphic systems in the Triangle (eolian, fluvial, mass wasting, and soil redistribution) and the ways they are likely to be affected by four climate change scenarios (warmer and drier, warmer and wetter, cooler and drier, and cooler and wetter), with the focus on the first scenario as being the most likely for the southern prairie region. The report begins with an overview of the Triangle's geological setting and its climate, vegetation, and soils. It then discusses the four geomorphic systems, and concludes with a qualitative discussion of the potential impacts of the climate change scenarios on each system and related human activities such as agriculture.
