||Map of the arctic coast, showing typical routes for the Northwest Passage, superimposed on charted median ice concentration (1971-2000) for September 3, where ice concentration ranges from less than 1/10 to 9+/10. The map shows that a potential, southern shipping route through the Northwest Passage is almost feasible based on these concentrations, and will become more viable with further warming.

||Graph of annual contribution to Canadian, North West Territories and Nunavut GDP (2001 - 2020) of the Tibbitt to Contwoyto Winter Road and associated projects. North West Territories were the greatest contributor, Nunavut a very minor contributor and the rest of Canada a small contributor. Total average contributions were approximately 1000$ with an increase to an average of 2000$ from 2005 to 2012.
||Flow chart showing how warmer winters and warmer and drier summers over the late 20th century led to overwintering of beetles, enabling of spruce bark betters to complete life cycle in 1 year and a decreased ability of white spruce to resist insect attack due to drought stress. Combined, these factors caused spruce bark beetle populations to reach epidemic levels in the southwest Yukon, which then led to widespread mortality of spruce trees. This tree mortality affected ecosystem function and structure, increased fire hazards and changed economic activities. Overall, this culminated in impacts on forest management, for both ecosystem functioning and community stability and benefits. The source of this Figure is Ogden, 2006.
||this graph shows the % distribution of 15 harvested organisms in Nunavut between 1996 and 2001. These organisms include land animals (e.g., caribou, fox), birds (e.g., snow goose, elder duck) and fish (e.g., arctic char, lake trout). The key message of the graph is that Arctic Char represents 45% of the harvest, while each of the other 14 organisms account for less than 10% each.
