Extreme heat breaks temperature records in central and eastern Europe

Record-breaking temperatures have been registered across central and eastern Europe, with Slovakia reporting a high of 42C (108F) in Dolné Plachtince, while Austria and Hungary also exceeded their previous temperature records. The extreme conditions have triggered widespread disruptions to critical infrastructure and prompted urgent responses from regional authorities.

Poland’s power generation capacity has been significantly impacted by the heat wave, as two major coal-fired power plants were forced offline due to critically low water levels in the Vistula River affecting cooling systems. The closures removed approximately 1.3GW from the nation’s power supply. Polish Prime Minister Donald Tusk issued guidance to employers regarding workplace safety measures, recommending the provision of air conditioning and cold water for workers. Hungary’s leader reported that one turbine at the Paks nuclear power station would return to operation, though electricity conservation remained necessary during peak heat conditions.

The broader humanitarian and environmental consequences of the extreme weather have become apparent. Germany has experienced an estimated 11,900 heat-related deaths during the summer according to the Robert Koch Institute. Climate activists demonstrated outside Germany’s chancellery, drawing connections between fossil fuel reliance and the public health crisis. Environmental organizations have characterized the situation as emblematic of how energy infrastructure dependent on carbon-intensive sources increasingly faces threats from the climate conditions it contributes to generating.

Wildfire activity has intensified across the region, with approximately 500,000 hectares burned across the European Union since the year began, concentrated primarily in Spain and France. Ukraine has experienced an additional 292,000 hectares of fire damage. Fire weather conditions—encompassing heat, dryness, and wind patterns—have exceeded previous records by substantial margins, with Austria experiencing more than double the previous record severity and Slovakia recording conditions 32% worse than historical norms for this period.

Scientific analysis from the World Weather Attribution consortium attributed the heat and drought patterns partly to global warming, determining that climate change increased the likelihood of such conditions by at least twenty-fold in Spain and double in France during the preceding month.
