欧洲正经历一场罕见的极端热浪。意大利全国27个主要城市同时发布最高级红色预警，这是该国年内首次全网络同时达到最高预警等级[1]。与此同时，奥地利在7月中旬于Bad Deutsch-Altenburg村测得41.2℃（106.2℉）的国家最高温度纪录[1]。多国气温普遍超过40℃（104℉）[1]。
这场热浪带来了严重的连锁危机。匈牙利核电站因多瑙河水位创历史新低被迫大幅减产，产能降至约10%[1]，布达佩斯当晚最低气温亦创纪录达28℃（82℉）[1]。法国东南部Var地区于7月20日起发生大火，烧毁超过60平方公里（23平方英里）林地，为该地区近几十年来最大规模火灾[1]。奥地利的干旱形势也十分严峻，从1月1日至6月30日期间的降水量比长期平均值低27%，部分东部地区仅获正常降水的一半[1]。
科学家警告称，此类极端事件因气候变暖而变得更加频繁和剧烈[1]。
A severe heat wave is sweeping across Europe, triggering unprecedented public health warnings and infrastructure crises across multiple nations. Italy has issued red alert warnings—the highest alert level—simultaneously for all 27 major cities nationwide for the first time this year, marking an extraordinary escalation in heat emergency response.[1] Austria has recorded its highest temperature on record at 41.2°C (106.2°F), measured in mid-July in the village of Bad Deutsch-Altenburg.[1] The extreme temperatures have exceeded 40°C (104°F) across numerous countries in the region.[1]
The heat wave is straining critical infrastructure and natural resources across Central Europe. Hungary's nuclear power plant has been forced to reduce output to approximately 10 percent of its regular capacity due to record-low water levels in the Danube River, which is hampering cooling operations.[1] Budapest experienced a record-breaking overnight low temperature of 28°C (82°F).[1] In France, a major wildfire that began on July 20 in the Var region of the southeast has consumed over 60 square kilometers (23 square miles), making it the largest fire in that area in recent decades.[1] Austria's drought conditions have been severe, with rainfall from January 1 to June 30 running 27 percent below long-term averages, with some eastern regions receiving only half their normal precipitation.[1] Scientists have warned that such extreme weather events are becoming more frequent and intense due to climate change.[1]
