Europe's June 2026 heatwave killed at least 12,000 people excess of normal — confirmed by France24 analysis and reporting from Euronews, NYT, and Politico across nine countries. Climate scientists confirmed the heatwave would have been virtually impossible without fossil fuel emissions, linking the deaths directly to climate change. The post's prediction that this will worsen with continued emissions reflects mainstream climate modeling, though exact severity and timeline remain uncertain — the core causal link between emissions and heatwave mortality is scientifically established.
