A recent report highlights a potential 5-degree Celsius increase in temperatures for Canadians in the future due to climate change. The second edition of the Canada’s Changing Climate Report emphasizes the impact of human activities, particularly the burning of fossil fuels, on the environment. The federal government released a summary of the report’s conclusions, which indicate that Canada’s climate future depends on global efforts to fulfill climate commitments.
Nathan Gillett, a research scientist with Environment and Climate Change Canada and one of the report’s authors, emphasizes the importance of future emissions in determining temperature stability. The report forecasts intensified warming in Canada if current climate policies persist, leading to significant changes in the country’s climate conditions.
The report predicts a 5-degree Celsius increase in temperatures by 2081 to 2100, with winter temperatures in Nunavut potentially exceeding 10 degrees Celsius. Glaciers in western Canada are expected to lose over 75% of their ice, and there is a high likelihood of the central Arctic Ocean being ice-free during most Septembers.
Southern Canada is expected to face challenges such as longer and more intense summer droughts, increased frequency of flash flooding, and atmospheric river events. The report also warns of a lengthening fire season across Canada and projects a potential 6.9-degree Celsius temperature increase if countries abandon climate policies.
However, if global efforts successfully reduce greenhouse gas emissions and achieve net-zero around 2075, Canada’s climate may stabilize with an average temperature increase of 3.5 degrees Celsius. The Canadian Climate Institute stresses that the future is not predetermined and that mitigation efforts can influence the severity of warming.
The institute emphasizes that cutting emissions globally will have a significant impact on the extent of temperature rise and its consequences for Canadians. Every degree of warming that is avoided can save lives, protect communities, and prevent economic losses. Climate advocacy groups urge immediate action to reduce emissions, citing recent extreme weather events as evidence of the urgent need to address climate change. Canada’s commitment to reducing emissions and achieving net-zero by 2050 remains a priority.
