2026年全球正经历极端高温天气，多地气温屡创新高。新疆吐鲁番艾丁湖7月21日达到50.2℃，成为该年首个突破50℃的国家级气象站[1]。与此同时，重庆、新疆、四川等地7月气温创下自1961年有完整观测记录以来的新高[1]。中国东北地区受极端天气影响尤为显著，长春、沈阳、铁岭等多地夜间最低温接近30℃，打破观测史最高纪录[1]。全国共有40个国家级气象站日最高气温达到或突破历史极值[1]。
极端高温现象并非中国独有。国际上，意大利25座主要城市进入红色高温预警，美国拉斯维加斯气温一度达到46℃[1]。世界气象组织预测，2026年8月至10月全球几乎所有陆地区域气温将高于正常水平[1]。气象学家指出，超强厄尔尼诺现象加剧了全球变暖，并预测2026年可能成为人类有气象记录以来最热的年份之一，甚至可能超越2024年[1]。
A severe heat wave engulfed much of the world in 2026, with multiple regions experiencing unprecedented high temperatures. On July 21, the Ayding Lake weather station in Turpan, Xinjiang reached 50.2°C, marking the first national-level meteorological station in 2026 to break the 50°C threshold [1]. Chongqing, Xinjiang, and Sichuan all recorded their hottest July since comprehensive observations began in 1961 [1]. Across China, approximately 40 national weather stations registered daily maximum temperatures that matched or exceeded their historical records [1].
The northeastern regions of China also experienced extreme overnight conditions, with cities including Changchun, Shenyang, and Tieling recording nighttime lows approaching 30°C, shattering the highest temperatures ever documented in their observation histories [1]. Meanwhile, 25 major Italian cities entered red-alert heat warnings, and Las Vegas experienced temperatures reaching 46°C [1].
The World Meteorological Organization projected that from August through October 2026, nearly all land regions globally would see temperatures exceed normal levels [1]. According to meteorological experts, 2026 could become one of the hottest years in human recorded history, potentially surpassing 2024, with an intensifying super El Niño phenomenon exacerbating global warming [1].
