A recent report highlights that Canadians need to prepare for a future with temperatures 5 degrees Celsius higher due to human-induced climate change. The second edition of the Canada’s Changing Climate Report underscores the significant impact of burning fossil fuels on the planet’s warming. Released by the federal government, the report examines potential scenarios based on global emission levels and climate commitments.
According to the report, if current climate policies persist globally, Canada is projected to experience a substantial temperature rise by 2081-2100, with some regions like Nunavut potentially seeing over 10 degrees Celsius of warming in winter. The report predicts a drastic loss of over 75% of glaciers in western Canada and a high probability of the central Arctic Ocean being ice-free in most Septembers.
Southern Canada, where the majority of the population resides, faces challenges too. The report warns of prolonged and intensified summer droughts, along with an increased frequency of flash flooding and atmospheric rivers. It also notes the lengthening of the fire season across the country.
The report emphasizes that if countries maintain their current climate policies, Canada’s average temperature could rise by 5 degrees Celsius. However, with a concerted effort to reduce greenhouse gas emissions and achieve net-zero by 2075, the projected warming could be limited to 3.5 degrees Celsius.
While the report paints a concerning picture, the Canadian Climate Institute asserts that the projected 5-degree warming is not inevitable. By taking immediate action to cut emissions globally, the institute believes that Canada can mitigate the worst impacts of climate change. Each degree of warming avoided could save lives, protect communities, and save billions of dollars for the Canadian economy.
In response to the report, a climate advocacy group called for stronger emission reduction measures, linking recent extreme weather events like Toronto’s flash flooding to climate change. Canada’s environment minister reiterated the country’s commitment to reducing emissions and achieving net-zero by 2050, emphasizing the urgency of addressing climate change while ensuring energy security and industrial sustainability.
