Summary This chapter provides an assessment of observed and projected changes in the Canadian cryosphere. This updates a review conducted as part of the 2007/2008 International Polar Year and a previous overview of Canada’s changing climate, as well as complementing recent assessments of the global and Arctic cryosphere. When appropriate, the longest available datasets of continuous surface measurements from observation sites are provided (for example, glacier mass balance, permafrost temperature). Otherwise, validated datasets from remote sensing andland surface models are utilized to provide information for large areas (for example, sea ice concentration,snow cover fraction, lake ice cover). The historical periods vary between components of the cryosphere, depending on the available data, but extend from at least 1981 to present. Projected changes to the cryosphereare based on state-of-the-art climate model simulations from the fifth phase of the Coupled Model Intercomparison Project (CMIP5)
Local Relevance NWT snow and ice are being greatly affected by climate change
