Extreme Heat Could Make Parts of the Planet Uninhabitable, Study Warns

Douglas McIntyre, Editor-in-Chief at Climate Crisis 24/7, discusses new Harvard research showing that humans may not survive prolonged exposure to extreme heat—specifically temperatures around 107°F. The study suggests some areas of the world may become uninhabitable within the next few decades, raising urgent questions about climate migration and global preparedness. McIntyre highlights the severe implications for densely populated cities, where millions may be trapped without the means to relocate or cool themselves.
