世界气象组织：2025年二氧化碳等主要温室气体浓度创历史新高，影响将持续数百年
世界气象组织（WMO）发布的最新《温室气体公报》显示，2025年地球大气中二氧化碳等主要温室气体浓度升至有观测记录以来的最高水平。世界气象组织指出，温室气体一旦进入大气可存留很长时间，其造成的增暖影响将持续数百年。
在主要温室气体中，二氧化碳存留时间最长、作用最大，人类活动尤其是化石燃料的燃烧是其浓度持续上升的主因；甲烷、一氧化二氮等其他主要温室气体浓度同样居高不下。大气中温室气体增多意味着地球系统捕获的热量继续增加，与全球平均气温上升、海平面上升及极端天气事件增多密切相关。
世界气象组织每年发布《温室气体公报》，汇总其全球大气监测网各观测站的数据，为各国气候政策与联合国气候谈判提供科学依据。该组织多次表示，当前各国的减排步伐与《巴黎协定》目标之间仍有明显差距。
WMO: Carbon Dioxide and Other Key Greenhouse Gases Hit Record Highs in 2025, Effects to Last for Centuries
The World Meteorological Organization (WMO), in its latest Greenhouse Gas Bulletin, reports that concentrations of carbon dioxide and other key greenhouse gases in Earth's atmosphere rose to the highest levels on record in 2025. The agency notes that once emitted, greenhouse gases remain in the atmosphere for a long time, and the warming they cause will last for centuries.
Carbon dioxide is the longest-lived and most significant of the major greenhouse gases, and human activity — above all the burning of fossil fuels — is the main driver of its continued rise. Concentrations of methane, nitrous oxide and other key gases also remain elevated. Higher concentrations mean Earth's system traps more heat, closely linked to rising global average temperatures, sea-level rise and more frequent extreme weather events.
The WMO publishes the Greenhouse Gas Bulletin every year, compiling data from its Global Atmosphere Watch network to provide a scientific basis for climate policy and UN climate negotiations. The agency has repeatedly said that countries' current pace of emissions cuts still falls well short of the goals of the Paris Agreement.
