A recent study has revealed the severe ecological consequences of the 2021 heat dome in North America, with over 75% of wildlife species studied being negatively affected. Published in Nature Ecology and Evolution, the research highlights the widespread damage caused by this extreme weather event, driven by climate change. Temperatures soared above 50°C (122°F) across the western United States and Canada, leading to a nearly 400% increase in wildfire activity, which devastated habitats and endangered countless animals.
