地球正经历前所未有的变暖危机，多项关键气候指标接连打破历史纪录 1。全球平均地表温度连续6天超过17.0°C，仅2023、2024及2026年突破此阈值 1。海表温度连续55天刷新日纪录，比此前7月26日纪录高0.14°C，超出1991至2020均值3.8个标准差 1。尼诺3.4区域海温比1991至2020均值高约2.3°C，连续58天刷新日纪录 1。CFSv2模型预测本次厄尔尼诺峰值尼诺3.4异常约4.3°C，远超1997至1998年2.8°C的历史纪录 1。1877年最强厄尔尼诺导致全球4000万人死于饥荒 1。2027年全年有较大概率比1850至1900年工业化前基线高出1.70°C 1。
地球能量失衡显示行星正以每秒约14颗广岛原子弹的速率吸热 1。2026年5月CERES数据显示地球能量失衡相当于每秒约14颗广岛原子弹，每日约120万颗，过去12个月累计约4.4亿颗 1。36个月滑动平均反照率从2003年2月的29.33%降至2026年5月的28.67%，损失约2.25% 1。截至7月26日，北极海冰范围历史第8低，南极第5低，全球合计第4低，低于1991至2020均值约2.1个标准差 1。极地海冰虽未破年度最低但长期前景严峻 1。PIOMAS北极海冰体积与厚度数据源被关闭 1。
The Earth is currently enduring an unprecedented warming crisis, with the global average surface temperature surpassing 17.0°C for six consecutive days, a threshold that has only been breached in 2023, 2024, and 2026 1. Projections indicate a high probability that the full year of 2027 will exceed the 1850-1900 pre-industrial baseline by 1.70°C 1. Oceanic temperatures are equally alarming, as sea surface temperatures have broken daily records for 55 consecutive days, exceeding the previous July 26 record by 0.14°C and sitting 3.8 standard deviations above the 1991-2020 average 1.
In the Niño 3.4 region, sea temperatures are approximately 2.3°C above the 1991-2020 average, marking 58 consecutive days of new daily records 1. The CFSv2 model forecasts that the peak Niño 3.4 anomaly for the current El Niño will reach roughly 4.3°C, vastly outstripping the historical record of 2.8°C established during the 1997-1998 event 1. To provide historical context, the most powerful El Niño in 1877 triggered a global famine that resulted in 40 million deaths 1.
Planetary energy imbalance data from CERES in May 2026 reveals that the Earth is absorbing heat at a rate equivalent to about 14 Hiroshima atomic bombs per second, totaling approximately 1.2 million daily and roughly 440 million over the past 12 months 1. This crisis is compounded by a declining albedo, with the 36-month rolling average falling from 29.33% in February 2003 to 28.67% in May 2026, reflecting a loss of about 2.25% 1. As of July 26, the Arctic sea ice extent ranks as the eighth lowest on record, the Antarctic is the fifth lowest, and the global combined total is the fourth lowest, all falling approximately 2.1 standard deviations below the 1991-2020 average 1. Furthermore, the data source for PIOMAS Arctic sea ice volume and thickness has been closed 1.
