Canada's 2025 Heat Waves Linked to Human-caused Climate Change | AI News Digest
In a notable development attracting worldwide attention, Canada faced a series of intense heat waves in 2025, with a significant portion of these events attributed to climate change driven by human activities, according to Environment and Climate Change Canada (ECCC). Researchers employed a newly launched rapid extreme weather attribution system to assess the ten most severe heat waves recorded in July and August. Their findings indicated that nine of these heat events were considerably more likely to occur as a result of climate change. By comparing current climate patterns to those from pre-industrial times, the analysis highlighted that such extreme temperatures would have been highly unusual without human influence. Particularly striking was a heat wave affecting Atlantic Canada, which was found to be at least ten times more probable due to climate change. This ongoing investigation emphasizes the rising frequency and severity of extreme weather phenomena linked to human-induced factors.
