| Abstract | The Palliser Triangle is the driest portion of the Canadian Prairies, and one of the most climatically sensitive regions in Canada. The potential biophysical impacts of future climate changes are
addressed in the Palliser Triangle Global Change Project through an improved understanding of Holocene climate and hydrological changes, and associated landscape response.
Water availability, particularly in relation to groundwater fluctuations,
is the single most important factor controlling regional environmental change. Three major intervals are defined for the Holocene, reflecting climate, hydrological, and human factors, and geomorphic activity during those intervals is assessed.
Projections of future geological impacts must be based on a thorough understanding of hydrological and geomorphic system dynamics, including the importance of thresholds and antecedent conditions. Systems that are still responding to past major
disturbances are unlikely to show a predictable response to climate change. Significant response and relaxation times in many systems indicate that some climate impacts will not be immediately apparent, but may have considerable long-term
consequences. |
