Climate change is affecting both the quality and quantity of our water. Warmer temperatures can increase rain, snowfall, and moisture, which affect water levels and increase the chance of flooding, erosion, and severe weather events.
Droughts may be more common in areas that often endure dry spells. Shared water sources such as reservoirs, rivers, and groundwater for wells are in danger of running dry.
Droughts can significantly impact agriculture, recreation and tourism, energy production, and transportation. Hotter summers would increase water use for irrigation, directly changing the water table and reducing wetlands.
Environmental Impacts on Water
Canada's freshwater ecosystems are at risk because of climate change. Significant river flows can be affected, and extreme weather events can contribute to more water or not enough water moving over the land. Climate change can reduce the flow in major rivers by as much as 20% this century.
