A scorching heatwave is currently wreaking havoc across southern Europe and parts of Germany, as temperatures continue to soar to record highs. The upcoming wave of heat from the Sahara is expected to push temperatures even higher in certain regions of Italy this weekend. The city of Athens is particularly affected, with nighttime temperatures not expected to drop below 25°C (77°F) for the next 15 days. In an effort to seek relief, many residents are flocking to nearby beaches as early as 6 a.m. Delivery services have been halted between midday and 5 p.m., and even the iconic Acropolis will be closed during this period. The severity of the heat has even resulted in some tourists requiring first aid at the ancient site.
The European Space Agency has issued a warning, predicting that the region's all-time high temperature of 48.8°C (119.8°F) could potentially be surpassed this month in Sicily and Sardinia, two Italian islands. This continuous occurrence of extreme weather is a consequence of climate change, which is increasing the frequency of such events in the Northern Hemisphere. The World Meteorological Organization stresses the urgent need to reduce greenhouse gas emissions, as these extreme weather events are significantly impacting human health, ecosystems, economies, agriculture, energy systems, and water supplies. Petteri Taalas, the Secretary-General of the WMO, emphasizes the necessity for society to adapt to this new normal.
A recent study revealed that last year's summer heatwaves in Europe resulted in over 60,000 deaths. Unfortunately, many countries in the region are ill-prepared and poorly adapted to handle the consequences of global warming. Most homes are designed to provide warmth during cold weather, thus lacking the necessary infrastructure to deal with intense heat. As the Cerberus anticyclone dissipates, a new heatwave named Charon, after the ferryman in Greek mythology who transported souls to the underworld, is set to intensify temperatures across parts of Italy.
Consequently, heat warnings have been issued for various cities in Italy. The transport Minister, Matteo Salvini, has made an executive order to intervene in a strike by train workers, citing the heatwave as the reason. The strike, which began on Thursday, has been reduced from 24 hours to 12 hours. Furthermore, the Iberian Peninsula, particularly Madrid, is experiencing sweltering heat, approaching the record temperature of 42.7°C (108.9°F) set in August 2021. The Spanish capital is forecast to reach 42.1°C (107.8°F) on July 18.
Meanwhile, Berlin is bracing for temperatures above 35°C (95°F) on Saturday, which would be the hottest day of the year so far. The heatwave is not only affecting the transport system but also putting pressure on energy systems. Electricite de France SA has announced a reduction in production at one of its nuclear reactors due to the limited amount of water that can be discharged into the Rhone River. Cooling the reactors with water is necessary before releasing it into the river, as overheating the waterway poses a threat to fish and other wildlife. Similarly, Hungary's Paks nuclear plant has reduced output due to the rising temperature of the Danube River, which is used for cooling purposes.
The extreme weather conditions are also warming seas in the Northern Hemisphere, putting marine life at risk of extinction and increasing the likelihood of invasive species that could harm fisheries. The WMO predicts that parts of the Mediterranean will exceed 30°C (86°F) in the coming days, mirroring reports of record-breaking temperatures off the coast of Florida.
Interestingly, while the majority of Europe is faced with extreme heat, the United Kingdom and the Nordics are experiencing relatively cooler temperatures for this time of year. Oslo is expected to dip to 8°C (46.4°F) on July 19, while London will have lows of 11°C (51.8°F) on Tuesday. Nevertheless, yellow wind warnings have been issued for Friday and Saturday in various parts of the UK as a result of low-pressure systems affecting the country.
