The climate risks of greatest concern to transportation operators, provincial governments, and municipalities in Atlantic Canada are extreme weather events and storm
surges. Hurricanes, high winds, heavy precipitation, and extreme snowfall have resulted in costly damage and shipping disruptions for marine ports, delayed flights and ferry services and washed-out roads and railways. As storm frequency and intensity
increases, these impacts will likely continue to be severe.
While most actions to enhance the climate resilience of transportation systems have been taken in response to past impacts from extreme weather, future climate risks (such as sea level
rise) are increasingly spurring planning and investments. Coordinated partnerships and initiatives suggest Atlantic provinces are actively engaged in adaptation planning. Risk assessments and regional cost-benefit analyses, which include
transportation systems within their scope, will help inform future decision-making.
Transportation practitioners are accounting for projected climate changes in the planning and operation of some roads, bridges, railways, and marine ports in
Atlantic Canada, but actions related to airports are less well-documented. While this is reflective of the dominance of road and marine transportation in the region, significant research gaps exist regarding adaptation strategies for all modes.
number of strategies are being specifically used to enhance the resilience of transportation infrastructure to flood risks. These include constructing physical barriers (seawalls, breakwaters, and dykes), improving stormwater management (updating
design flows, enlarging culverts) and relocating and/or elevating infrastructure.
Regionally-focused weather- and climate-monitoring technologies are helping transportation operators identify and adapt to climate risks in Atlantic Canada. Examples
include SmartAtlantic monitoring buoys to inform extreme-weather preparedness and better understand changes in ocean climate, and the CoastaL Impact Visualization Environment (CLIVE) tool, which allows users to visualize changing coastlines in Prince
Edward Island. These technologies assist with risk assessment and help practitioners communicate the magnitude of short- and long-term impacts to decision-makers.
|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.
