Canada is usually considered to be a country with abundant freshwater, but in its western prairie provinces (WPP), an area 1/5 the size of Europe, freshwater is scarce. European settlement of the WPP did not begin until the late 19th and early 20th centuries. Fortuitously, the period since European settlement appears to have been the wettest century of the past two millennia. The frequent, long periods of drought that characterized earlier centuries of the past two millennia were largely absent in the 20th century. Here, we show that climate warming and human modifications to catchments have already significantly reduced the flows of major rivers of the WPP during the summer months, when human demand and in-stream flow needs are greatest. We predict that in the near future climate warming, via its effects on glaciers, snowpacks, and evaporation, will combine with cyclic drought and rapidly increasing human activity in the WPP to cause a crisis in water quantity and quality with far-reaching implications.

Climate change is at the forefront of public consciousness today. Political initiatives to combat the social and economic effects of changing climate will affect the lives of everyone. Media reports often portray climate scenarios and the range of uncertainty accompanying predictions. How does a reader approach the science behind the headlines? The goal of this book is to explain climate change science by examining the recent Ice Age history so spectacularly exposed in the Canadian Rocky Mountains landscape. Local and global sources of paleoclimate information are combined with dating techniques to unravel the glacial history of the Rockies over the last 30,000 years. The illustrated road log guide can be used by the armchair reader or the traveller to visit the landscape features essential to the interpretation. The Burgess Shale Geoscience Foundation is a non-profit charitable organization dedicated to increasing public understanding of the geosciences. Its teaching themes demonstrate the use of physics, biology, chemistry and mathematics in solving science questions and problems. The diverse program includes public lectures, teacher workshops, school programs and guided hikes. The Foundation conducts educational hikes to the Burgess Shale soft-bodied fossil deposit and the Mt. Stephen trilobite beds, both UNESCO World Heritage sites in Yoho National Park.
