Nova Scotia, like many regions worldwide, is facing the impacts of climate change. A recent report from the provincial government has highlighted a new primary risk and areas within the province that will encounter increased challenges or benefits in the years ahead.
The updated climate change risk assessment, released by the province in late December, builds upon the initial assessment from 2022. Utilizing the latest climate data available, the report examines risks projected for the 2050s and 2080s.
In addition to existing threats such as heatwaves and diseases transmitted by insects, the latest assessment identifies a new significant risk for the province in the 2050s: diminished water quality. The report warns that heavier rainfall and rising temperatures could compromise surface water quality, potentially leading to health and safety concerns. It mentions the potential proliferation of blue-green algae in lakes as an example.
The severe drought experienced in Nova Scotia during the hot, dry summer and fall underscored water-related issues, including drought conditions, heightened wildfire risks, and challenges for firefighting efforts. Previous assessments had already predicted a shift towards more rain and less snow in the region in the upcoming years.
The report categorizes climate risks into five main themes – disaster resilience, human health, environment, infrastructure, and economy and workers. It emphasizes the importance of understanding these risks to support adaptation strategies effectively. For instance, suggestions include constructing infrastructure in less flood-prone areas and planting more trees to mitigate heat-related risks.
The latest assessment also explores how different parts of the province will be impacted by climate change. Six counties, including Cape Breton, Colchester, Cumberland, Halifax, Hants, and Pictou, are expected to face heightened climate risks by the 2050s due to various factors. Conversely, counties like Hants, Annapolis, Guysborough, Kings, and Queens might experience some benefits from climate change, such as extended tourism seasons and reduced infrastructure damage from freeze-thaw cycles.
The report aims to assist communities, first responders, and municipalities in adapting to climate risks by providing tailored insights for each region. The next risk assessment is scheduled for 2030, coinciding with the province’s legal obligation to generate 80% of its electricity from renewable sources and cease the use of coal-fired power plants for electricity generation.
In conclusion, Nova Scotia’s commitment to addressing climate risks and fostering resilience is crucial as the province navigates the challenges of a changing climate landscape.
