Résumé du colloque

Using the two climatic change scenarios by the Canadian Climate Centre, an attempt has been made, using snowcover suitability percentiles, to estimate the resilience and sensitivity of downhill skiing in the Laurentians to the suggested changes in temperature and precipitation. The scenarios suggest an average winter temperature increase in the range of 0 to 16% for precipitation and 7.6 to 9.3°F (4.2 to 5.2°C) for temperature. These changes could possibly result in a reduction of the marginally reliable and reliable ski seasons at the Laurentians by 41 to 91% respectively. It would appear then that downhill skiing in the Laurentians has reasonable resilience to the suggested conditions of one scenario but not the other. In addition, the sensitivity analyses indicate that the ski season length in this part of Canada is little affected until the average winter temperature increases by 5°F (2.8°C).
