Overview
- By mid‑August, a string of five heatwaves pushed July to be the hottest on record globally, a NOAA finding that followed repeated Western European temperature records reported by NASA and Copernicus.
- Provisional monitoring from EuroMomo and national tallies put excess summer deaths at roughly 30,000 or more across Europe, with Germany reporting about 14,000 heat‑linked fatalities.
- The heat and drought sharply raised electricity demand while reducing hydropower and forcing some nuclear and thermal plants to cut output because rivers were too warm or too low for cooling.
- Solar generation rose about 17 percent on heatwave days and helped meet daytime demand, but early evening price spikes showed the grid’s need for more battery storage to carry solar power into the night.
- Widespread wildfires, record‑low rivers and emergency government actions — from mass evacuations in France to interventions on the Danube — are prompting calls for faster adaptation, grid flexibility and investment in storage.
