# Global extreme heat impacts in summer 2026 > Live situation record from CLSTR: https://clstr.news/situations/global-extreme-heat-impacts-in-summer-2026 > Updated: 2026-09-19T23:22:29.000Z. Sources: 10. Developments: 2. Reports from Climate Central indicate that during the summer of 2026, over 1.5 billion people globally were exposed to at least one month of dangerous or “at-risk heat” due to human-induced climate change. In Europe, nearly nine out of ten residents faced hazardous temperatures. France recorded its hottest summer since 1900, with temperatures approximately 3.5°C above the 1991-2020 norm and 53 days of heatwaves. Asia saw high numbers of affected individuals, including 117 million in India. In Turkey, approximately 54.3 million people were exposed to dangerous temperatures for more than 30 days. The average resident in Turkey faced 32 additional days of risky heat that would not have occurred without climate change, with the city of Adana experiencing the highest increase at 40 additional days. Scientists attribute these extreme conditions, which have led to record wildfires and droughts, to the burning of fossil fuels. Kristina Dahl, Vice President of Science at Climate Central, described the findings as an “alarming global pattern” that pushes communities beyond safe physical limits. ## Timeline ### 2026-09-19: Climate change drove extreme heat for 1.5 billion people in summer 2026 A Climate Central study shows 1.5 billion people globally faced extreme heat in summer 2026 due to climate change, with significant impacts in Turkey and Europe. 3 sources. https://clstr.news/cluster/climate-change-drove-extreme-heat-for-15-billion-people-in-summer-2026 ### 2026-09-16: Climate Central report: 1.5 billion people affected by extreme heat Over 1.5 billion people faced dangerous heat for at least a month between June and August, driven by climate change and fossil fuel use, according to a new analysis by Climate Central. 7 sources. https://clstr.news/cluster/climate-central-report-15-billion-people-affected-by-extreme-heat --- Cite as: Global extreme heat impacts in summer 2026.
