European heatwave curtails cheese output, fuels wildfires, strains Italy's grid
A June 2026 heatwave swept across Europe, with temperatures soaring to about 40 °C. In Italy's Parmigiano Reggiano region, cows produced up to 10 % less milk, cutting cheese yields and raising costs for farms and warehouses. The sector, worth roughly €4.5 billion annually, relies heavily on the United States as its top buyer.
The extreme heat also ignited wildfires in France and Spain, destroying homes in rural French villages and threatening the historic vineyards of Bordeaux with lingering “zombie fires.” A separate blaze near a nuclear plant in Suffolk, United Kingdom, kept operators on high alert.
Rome responded by unveiling a new heat‑health operational plan that adds green public spaces, water fountains, climate shelters and measures to bolster grid resilience. Yet the peak electricity demand hit 2.1 GW, triggering localized blackouts and highlighting limited spare capacity in Italy's power system.
