Climate change increases health risks with extreme summer heat and wildfires

Rising temperatures and wildfires fueled by climate change are posing significant health risks across Canada, with humid conditions exacerbating the effects.

Shannon Waters and Emma McIntosh report for The Narwhal.

In short:

Eastern Canada experienced a heat dome in June 2024, with temperatures feeling as high as 40°C due to humidity.
High humidity complicates the body's ability to cool down, increasing the risk of heat-related illnesses.
Prolonged exposure to extreme heat and wildfire smoke can worsen respiratory and cardiovascular conditions.

Key quote:

"Some people may not be in the habit of protecting themselves from heat, given that this is early in the season. It’s still really important to prepare, particularly for people that may require assistance."

— Peter Berry, Health Canada spokesperson

Why this matters:

Rising temperatures and increased frequency of heat domes, driven by climate change, heighten the health risks of extreme heat and poor air quality.
