A recent analysis revealed that Canadians faced an increase in “risky heat” days this summer, attributed to climate change. The study conducted by Climate Central, a non-profit organization, found that on average, Canadians had 13 additional days of extreme heat between June and August. These “risky heat” days are defined as temperatures exceeding 90% of local temperatures recorded between 1991 and 2020.
Globally, the report highlighted that over 955 million individuals experienced 30 or more days of “risky heat” due to climate change. The impact varied among different regions, with cities like Vancouver and Windsor, Ont., having different thresholds for extreme heat days. Kristina Dahl, the vice-president of science at Climate Central, emphasized that higher temperatures pose health risks, particularly for vulnerable populations like older adults.
The summer also witnessed deadly heat waves in Canada and Europe, leading to tragic consequences. The study linked these extreme heat events to indirect risks such as wildfire smoke, which can result in air pollution and premature deaths. Canada experienced its second-worst wildfire season this year, causing significant health impacts.
Notably, Environment Canada’s rapid analysis revealed that climate change made extreme heat waves in Canada more likely. The study found that certain heat waves were twice or even ten times more probable due to climate change. Experts warn that if emissions are not reduced promptly, the consequences of climate change will continue to escalate, affecting communities, ecosystems, and economies worldwide.
As temperatures rise globally, experts stress the urgency of taking immediate action to mitigate the impacts of climate change. They advocate for measures such as improving access to air conditioning, implementing policies to protect outdoor workers from extreme heat, and providing community support for those at risk. Ultimately, the report underscores the pressing need to reduce fossil fuel emissions to safeguard the planet and its inhabitants from the escalating effects of climate change.
