在青藏高原记录地球大气变化 在青藏高原海拔3816米的瓦里关山顶，欧亚大陆腹地唯一的大陆型全球大气本底站——瓦里关全球大气 本底站已连续运行30多年。这里产生的长期序列观测数据及"瓦里关曲线"，被持续纳入世界气象组织温 室气体公报，成为刻画全球气候变化趋势的重要科学依据。 2025年9月，习近平主席在联合国气候变化峰会上发表视频致辞时强调，应对气候变化是一项紧迫而长 期的任务。让我们积极行动起来，推动实现人与自然和谐共生的美好愿景，守护好我们共同的地球家 园！ 立高原、望全球，观风云、惠世界。2026年2月1日起，《青海省瓦里关全球大气本底站保护若干规定》 将正式施行，这意味着，瓦里关站的科学价值获得了地方法规层面的系统保障。从填补观测空白到记录 绿色低碳转型之路，在高山之巅，瓦里关站见证了我国参与全球气候治理的主动担当。 这是瓦里 依托30多年不间断观测，瓦里关站积累了连续、长期的大气二氧化碳浓度观测数据。据此绘制而成的变 化曲线——"瓦里关曲线"，反映了大气二氧化碳月平均浓度的长期变化，与美国夏威夷冒纳罗亚全球大 气本底站的观测结果高度一致。 两处全球大气本底站，一个代表欧亚大陆腹地，一个代表太平洋海洋型 ...

Core Insights - The China Meteorological Administration released the "China Greenhouse Gas Bulletin (2024)", which is a key decision-making product for addressing climate change and aligns with the World Meteorological Organization's global bulletin [1] Group 1: Greenhouse Gas Concentrations - In 2024, the annual average concentration of carbon dioxide at the Wuliang Station reached 424.9 ppm, an increase of 3.5 ppm from 2023, which is consistent with the global average [1] - The annual average concentrations of methane and nitrous oxide were recorded at 2003 ppb and 338.4 ppb, respectively, slightly above the global average [1] Group 2: Carbon Emissions - Human-induced carbon emissions in China are projected to increase by approximately 0.6% in 2024 compared to 2023, a significant reduction from the previous year's growth rate and lower than the global increase of 0.8% [1] Group 3: Monitoring Network - Since the early 1990s, the China Meteorological Administration has conducted greenhouse gas observations at the Wuliang National Atmospheric Background Station, establishing a national monitoring network that includes 1 WMO global background station, 7 regional background stations, 11 pilot background stations, and over 120 greenhouse gas observation stations [1]
