世界气象组织表示，2025年温室气体浓度创下历史新高，二氧化碳浓度达到426.8ppm，为工业化前水平的153%。
Greenhouse gas levels hit record highs in 2025, with carbon dioxide at 426.8 ppm, or 153% of pre-industrial levels, the WMO said.
甲烷、一氧化二氮和六氟化硫也创下历史新高，世界气象组织警告称，这些气体将继续吸收更多热量，并加剧极端天气。
Methane, nitrous oxide and SF6 also reached record highs, and the WMO warned these gases will keep trapping more heat and worsening extreme weather.
世界气象组织预计，由于化石燃料燃烧和强烈的厄尔尼诺现象，2026年二氧化碳浓度将再次上升。
The WMO expects CO2 to rise again in 2026 because of fossil fuel burning and a powerful El Nino.
AI生成 日内瓦——世界气象组织在10月27日发布的一份报告中表示，2025年大气中的温室气体浓度达到前所未有的高水平，可能进一步使地球升温，并导致更多极端气候事件。
AI generated GENEVA – Greenhouse gas levels in the atmosphere reached unprecedented highs in 2025, potentially further warming the planet and leading to more extreme climate events, the World Meteorological Organization (WMO) said in a report on Oct 27.
报告称，2025年全球大气二氧化碳平均浓度达到426.8ppm，约为1750年工业化前水平的153%。该浓度较上一年上升2.8ppm，年度增幅超过过去十年的平均水平。
The global average concentration of atmospheric carbon dioxide reached 426.8 parts per million (ppm) in 2025, about 153% of the 1750 pre-industrial level, the report said. The level rose by 2.8 ppm from the previous year, a bigger annual increase than the average over the past decade.
其他重要温室气体——甲烷和一氧化二氮——的浓度在2025年也创下历史新高，分别为工业化前水平的267%和126%。该报告衡量的是大气中累积的气体总量，而非年度新增排放量。
Concentrations of other important greenhouse gases – methane and nitrous oxide – reached record highs in 2025, standing at 267% and 126% of pre-industrial levels, respectively. The report measures the amount of gas that accumulates in the atmosphere, not new annual emissions.
世界气象组织将与11月在土耳其安塔利亚举行的COP31联合国气候大会上的谈判代表分享这些发现，并警告称，强烈的厄尔尼诺现象可能在2026年将浓度推得更高。
The WMO will share the findings with negotiators at the COP31 UN climate conference in Antalya, Turkey, in November, and warned that a powerful El Nino could push concentrations higher in 2026.
“每增加一百万分之一都很重要，因为它会吸收更多热量。实际上，我们正在让海洋和大气超负荷运转，”世界气象组织副秘书长科·巴雷特说。
“Every additional part per million matters because it traps additional heat. In effect, we are supercharging the ocean and the atmosphere,” WMO deputy secretary-general Ko Barrett said.
“这意味着热浪、热带气旋和暴雨正在以超出我们历史基线所准备的速度加剧。”2026年，包括欧洲在内的世界部分地区出现了酷热的夏季气温，亚洲和其他地区也发生了毁灭性的洪水。
“That means that heatwaves, tropical cyclones, and rainstorms are intensifying faster than our historical baselines prepared us for.”In 2026, parts of the world including Europe saw scorching summer temperatures, as well as devastating floods in Asia and elsewhere.
厄尔尼诺可能加剧这一问题。世界气象组织表示，由于化石燃料燃烧和强厄尔尼诺现象的出现，预计2026年二氧化碳浓度将进一步上升，厄尔尼诺将导致天气更加干燥，使碳汇吸收排放更加困难。
El Nino likely to add to the problem The WMO said it expected carbon dioxide concentrations to rise further in 2026 due to fossil fuel burning and the onset of a powerful El Nino, which will cause drier weather and make it harder for carbon sinks to absorb emissions.
世界气象组织还对六氟化硫（SF6）表示担忧。六氟化硫是一种广泛用于电气设备的温室气体，该组织称其2025年的增幅创下历史新高。六氟化硫的全球变暖潜能值超过二氧化碳的2.4万倍，并且可在大气中存留1000年以上。
The WMO also raised concern about sulfur hexafluoride, or SF6, a greenhouse gas widely used in electrical equipment, saying its increase in 2025 was a record high. The global warming potential of SF6 is more than 24,000 times that of carbon dioxide and it can remain in the atmosphere for more than 1,000 years.
该机构还指出，氢浓度在上升，2010年至2024年间上升了5.3%。尽管氢不是温室气体，但用于生产、运输和储存氢的基础设施一旦泄漏，会影响大气化学过程，并间接导致气候变暖。利用可再生电力生产的氢可用作交通运输的低碳燃料。
The agency also pointed to rising hydrogen concentrations, which increased 5.3% between 2010 and 2024. Although hydrogen is not a greenhouse gas, leaks from infrastructure used to produce, transport and store it can affect atmospheric chemistry and indirectly contribute to warming. Hydrogen produced using renewable electricity can be used as a low-carbon fuel for transport.
世界气象组织表示，氢泄漏和六氟化硫的长期持久性都可能削弱全球能源转型带来的一些气候效益。
The WMO said both hydrogen leakage and the long persistence of SF6 could undermine some of the climate benefits of the global energy transition.
巴雷特说：“能源转型是必要且值得欢迎的，但与每一次转型一样，必须以明智的方式进行，并以环境观测为依据。”
“The energy transition is essential and welcome, but as with every transition, it has to be done in a smart way and informed by environmental observations,” Barrett said.
