Key Findings The Canadian North has experienced some of the most significant warming on the planet. From 1948 to 2014, the Arctic Tundra region warmed by 2°C, while the Arctic Mountains and Fjords region of Nunavut experienced a temperature increase of 1.6°C. The greatest warming (2.6°C) occurred in the Mackenzie District. These changes have considerable impacts on the people, land, ecosystems, and infrastructure. Permafrost degradation poses both immediate and future risks to northern transportation infrastructure. Warming temperatures have increased the vulnerability of roads, railways, and airport taxiways and runways to risks associated with ground settlement, slope instability, and buckling. Continued warming will further degrade permafrost, with implications for transportation safety, system efficiency, community services, and maintenance budgets in the North. Changes to the regional climate have reduced the operating windows and load capacities of some winter roads in recent years, in some cases resulting in costly adjustments. Winter roads serve as a key seasonal component of some territories' transportation infrastructure (particularly in the Northwest Territories) and are critical for community re-supply. While operating windows have always been variable from year to year, recent increases in surface temperature have shortened the operating season for some winter roads. This has resulted in the need for alternative, and often more costly, methods of shipping, such as air transportation. The climatic changes that are opening up northern marine waters to exploration and shipping are also making these activities more difficult. Increasing temperatures have led to a rapid decrease in sea ice extent, and reduced volumes of multi-year sea ice. While these changes are slowly opening up waterways to new navigational routes, the increased mobility of summer sea ice, as well as increased coastal erosion and storm surge flooding, present ongoing difficulties for shipping, exploration, and associated coastal infrastructure. While many adaptation techniques can be used to maintain roads, rail, and airport taxiways and runways on permafrost rich soil, some can be cost-prohibitive. Several practices rely on the availability of specialized equipment and materials, which can be expensive to transport to northern locations.
Summary(Plain Language Summary, not published)
This report presents the current state of knowledge about climate risks to the Canadian transportation sector, and identifies existing or potential adaptation practices. The report includes six regional chapters and one urban chapter which reflect the different climate change impacts, vulnerabilities and opportunities across Canada. Adaptation approaches are discussed and case studies highlight adaptation actions and practices. A synthesis chapter brings together the report's key findings. Co-led by Transport Canada and Natural Resources Canada, the development of this report synthesized over 700 publications and involved 42 lead and contributing authors, and over 228 expert reviewers.
