L'agence japonaise avertit des "journées cruellement chaudes" avec une température de plus de 40 degrés.

Japan's meteorological agency has issued a stark warning about the increasing frequency of "cruely hot days," defined as periods when temperatures exceed 40 degrees Celsius (104 Fahrenheit). The term, introduced this year by the Japan Meteorological Agency (JMA), aims to raise awareness about the dangers posed by extreme heat. On Wednesday, large parts of the country faced dangerously high temperatures, with several regions recording readings above the new threshold. Emergency officials described the conditions as a potential disaster, citing at least 14 deaths linked to heat-related illnesses in the previous week. The JMA reported that three major urban centers exceeded the 40-degree mark on Tuesday, marking these days as "kokushobi", a phrase translating directly to "cruelly hot day." These areas included Nagoya, a key economic hub in central Japan, and neighborhoods surrounding Tokyo in the eastern part of the country. Temperatures in these locations approached or surpassed the critical level, prompting widespread concern among local authorities and residents alike. Across the nation, heatstroke alerts have been activated in 41 of Japan’s 47 prefectures. This extensive coverage underscores the severity of the current weather pattern and highlights the need for heightened vigilance. While the JMA has not implemented any formal response measures under the new terminology, the alerts serve as a call to action for the public, particularly for vulnerable groups such as the elderly population, who are more susceptible to heat-related health issues. Emergency services have noted a rise in cases of heat exhaustion and dehydration, with some hospitals reporting increased admissions during the recent heatwave. Local governments have urged citizens to remain indoors during peak hours, ensure adequate hydration, and check on neighbors, especially those living alone. Public cooling centers have been opened in several municipalities to provide relief to those affected by the extreme conditions. The introduction of the "cruelly hot days" designation reflects growing concerns over climate change and its impact on Japan’s weather patterns. Over the past decade, there has been a noticeable increase in the number of days exceeding 35 degrees Celsius, with experts attributing this trend to rising global temperatures. The JMA’s decision to introduce a specific term for such conditions marks a shift toward more proactive communication strategies aimed at protecting public health. As the summer progresses, officials expect similar or even higher temperatures, potentially leading to further strain on healthcare systems and infrastructure. With the majority of the country already under heatstroke alerts, the focus remains on preventing additional casualties and ensuring community resilience against future heatwaves. The situation continues to evolve, with ongoing monitoring of temperature trends and public health responses.
