Regional Mean Sea-Level Rise Scenarios for the Canadian Coasts

Description

Just as the global mean sea level has risen over the past century, so have regional mean sea levels in many coastal areas of Canada, increasing the frequency, magnitude and duration of coastal flooding associated with storms. Existing estimates of future sea-level rise (SLR) vary widely, and variations in regional estimates may be even greater. Given these uncertainties, future potential SLR scenarios are useful to support decision-making related to the design and maintenance of coastal infrastructure under a changing climate.

This project will develop four regional mean SLR scenarios (lowest, intermediate-low, intermediate-high, and highest) for Canada's Atlantic, Pacific and Arctic coasts. The availability of these scenarios, and summary tables, will strengthen the ability of coastal communities as well as Fisheries and Oceans Canada to manage infrastructure in a way that recognizes and adapts to the flood risks associated with sea-level changes.
