A severe heat wave has gripped Europe, prompting Italy to place all its major cities on the highest heat alert. The extreme weather has pushed temperatures above 40 degrees Celsius (104 Fahrenheit) in several countries, prompting health warnings for millions of people. Across Europe, authorities are grappling with the consequences of extreme heat, including health alerts, record temperatures, drought-related disruptions, and wildfires.
The current heat wave has exposed vulnerabilities in public health systems, power generation, transportation networks, and tourism infrastructure, forcing governments and businesses to adapt to more frequent periods of extreme weather. Italy’s Health Ministry placed all 27 cities monitored under its national heat surveillance system on red alert, signaling a health risk for the entire population. Authorities urged residents and tourists to avoid direct sunlight during the hottest hours of the day, remain indoors where possible, and drink plenty of water.
Austria broke its national temperature record, with the mercury reaching 41.2 C (106.2 F) in the village of Bad Deutsch-Altenburg near the Slovak border. The country is also facing severe drought, with rainfall from January 1 through June 30 being 27% below the long-term average nationwide. Climatologist Alexander Orlik said some parts of the country had not experienced such dry conditions since 1885.
The heat wave has also affected other European countries, including Hungary, where prolonged drought and record-low water levels on the Danube River have severely affected the country’s only nuclear power plant. The plant’s operators have reduced output to about 10% of normal production, prompting the government to introduce emergency conservation measures. In Germany, concerns are growing over the impact of drought on transportation and industry as water levels on the Rhine and other rivers continue to fall.
France remains on high wildfire alert, with firefighters maintaining a large presence in the Var region after authorities said a major wildfire there was no longer spreading but remained capable of reigniting. The blaze has burned more than 60 square kilometers (23 square miles), making it the largest recorded in the region in recent decades. The heat wave has also reached its peak across the Balkans, with temperatures nearing 40 C (104 F) and authorities battling drought and wildfires.
Scientists and officials warn that such events are becoming more frequent and intense as the climate warms. Climate change drives more extreme summers, with prolonged heat, drought, and wildfire conditions increasingly becoming defining features of summer. Governments and businesses are being forced to adapt to more frequent periods of extreme weather, and environmental groups are urging authorities to focus on making rivers more resilient to climate change.
