Piki kač na velikih višinah: na Mount Everestu se je pojavila nova nevarnost

Europe has been gripped by an unprecedented heatwave that has pushed temperatures to record levels and brought about significant consequences beyond just breaking thermometers. The extreme weather pattern, which began at the end of June and continues into early July, has transformed daily life across much of the continent. Roads have softened under the relentless sun, train tracks have buckled due to thermal stress, hospitals are overwhelmed, schools have closed, and cities have turned their shadows into public assets. This heatwave is not merely another summer anomaly—it is a small-scale crisis with far-reaching implications for health, infrastructure, and the economy.

Across Central Europe, new temperature records were set almost daily. In Germany, the town of Coschen (Neißemünde-Coschen) in Brandenburg recorded 41.7 degrees Celsius, marking the highest temperature ever measured in the country since records began. Poland's city of Słubice reached 40.5 degrees Celsius, surpassing a century-old national record. In the Czech Republic, Doksany near Prague saw temperatures climb to approximately 41.9 degrees Celsius, while Hungary’s Budakalász recorded 40.7 degrees Celsius. These preliminary readings highlight a growing trend—what was once considered exceptional is now becoming increasingly common and widespread.

Slovenia, too, experienced its share of extreme heat. According to preliminary data from the Slovenian Environment Agency (ARSO), several meteorological stations exceeded their previous June temperature records. In Podnanos, the temperature reached 37.5 degrees Celsius, while Litija recorded 37.1 degrees, and Bežigrad in Ljubljana hit 36.9 degrees. At Ljubljana Airport, the temperature climbed to 34.7 degrees, and in Postojna, it reached 34.3 degrees. The heat persists into the following week, with high-level warnings issued for large parts of the country due to the intense thermal load.

The health impact of this heatwave has been severe. According to the World Health Organization (WHO), over 1,300 excess deaths have been recorded in Europe since June 21, linked to the extreme temperatures. WHO Director-General Tedros Adhanom Ghebreyesus referred to heat stress as a “silent killer” and warned that European homes, schools, and workplaces were not built to withstand such conditions. According to estimates from the German Meteorological Service, more than 380 million people in Europe have been exposed to temperatures above 30 degrees Celsius.

France has seen some of the most dramatic statistics. Between June 24 and 27, French health authorities noted nearly 1,000 additional deaths compared to normal expectations during this period. The largest increase was among individuals aged 65 and older, and there has also been a rise in deaths occurring at home. The heatwave has also led to tragic drownings, with multiple incidents reported in rivers, lakes, and ponds where people sought relief without proper supervision.

Beyond health concerns, the economic repercussions are substantial. High temperatures affect productivity and safety on outdoor work sites, particularly in construction, utilities, agriculture, delivery, and logistics. Urban areas face challenges as asphalt, concrete surfaces, and railway infrastructure become compromised. In Germany, problems arose in Leipzig's tram system, where the asphalt and sealing material on tracks began softening due to the heat, threatening safe travel. Some rail operators advised against non-essential travel, while electricity networks struggled with increased demand for cooling.

In agriculture, the heat brings higher rates of evaporation, faster soil drying, plant and animal stress, and an increased risk of wildfires. Italian authorities have raised concerns about low river water levels, while France and other countries are also grappling with similar issues. The cumulative effect of these factors underscores the multifaceted nature of the crisis, affecting both human health and the broader ecosystem.

The long-term implications of rising temperatures are evident even before the current heatwave. Slovenia’s climate has already warmed by approximately two degrees Celsius compared to mid-last century, with noticeable changes in all seasons. There are fewer days of severe cold, reducing the need for heating but increasing the demand for cooling, which leads to higher electricity consumption and greater strain on power grids. Households unable to afford effective cooling systems are especially vulnerable.

As the heatwave continues, the focus remains on mitigating its immediate effects and preparing for future occurrences. The WHO emphasizes the importance of preparedness, prevention, and stronger responses within healthcare systems. European countries are being urged to implement action plans to protect public health from extreme heat. With climate change accelerating the frequency and intensity of such events, the challenge ahead is clear: adapting to a world where extreme heat is no longer a rare occurrence but a recurring threat.
