Canada’s new climate assessment warns of at least 3.5 C of warming [1]
Canada’s latest federal climate assessment says the country will be about 2.7 C warmer than pre-industrial levels by 2050, close to twice the global average over that period. [1] Even if the world reaches net zero by 2050, the report says Canadian temperatures would rise to 3.5 C above pre-industrial levels before stabilizing around 2100, bringing decades of worsening wildfires, droughts, storms and extreme-weather damage.

The assessment strengthens the economic case for adaptation: Canadian Climate Institute analysis cited alongside the report estimates that every dollar invested in preparing infrastructure, communities and businesses for floods, heat and heavy rain can avoid up to $15 in losses. [1]
Key insights
- Environmental groups accused the Carney government of trying to bury the assessment after it was posted on a Thursday evening before the Labour Day weekend without the media briefings and ministerial availability used for the 2019 edition. [1]
- The federal environment department issued a news release saying the government remains committed to reaching net-zero emissions by 2050. [1]
- The eventual severity of warming remains sensitive to emissions: the report says cuts in Canada and abroad will help determine whether the country experiences more than 5 C of warming or about 3.5 C. [1]
