厄尔尼诺现象或使香港损失3000亿美元并缩短预期寿命:研究

一项由香港和新加坡大学联合开展的研究显示,厄尔尼诺现象可能在21世纪给香港造成高达3000亿美元的经济损失。该研究还发现,1982-83年和1997-98年两次强烈厄尔尼诺事件期间出生的香港人预期寿命可能缩短五至七个月。这项发表在《自然气候变化》杂志上的研究强调,厄尔尼诺不仅是短期天气异常,而是健康和经济损失的持久驱动力。

新加坡南洋理工大学与香港城市大学合作开展的研究分析了10个太平洋沿岸高收入国家和地区超过60年的死亡记录和经济数据。这些地区包括香港、新加坡、日本、澳大利亚、加拿大、南韩、美国、智利、台湾等地。研究发现,厄尔尼诺引发的极端天气事件对公共健康和经济造成持久影响,而非短暂异常。

具体而言,1982-83年厄尔尼诺事件导致预期寿命损失0.5年,而1997-98年事件则为0.4年。这相当于该研究覆盖的所有国家和地区在1982-83年群体经济损失达2.6万亿美元,在1997-98年群体则达4.7万亿美元。对于香港,该现象在21世纪可能造成3000亿美元的经济损失。

研究负责人之一、本杰明·霍顿(Benjamin Horton)等学者强调,厄尔尼诺是“健康和经济损失的持久驱动力”。另一位研究者德鲁巴焦蒂·萨曼塔博士(Dr Dhrubajyoti Samanta)指出,这种气候模式涉及太平洋变暖,会放大极端天气的影响。香港天文台等机构也出现在相关关键词中,但研究未具体提及其数据贡献。

这项研究提醒,面对气候变化,太平洋沿岸地区需加强应对厄尔尼诺的准备,以减轻其长期健康和经济负担。

Super Typhoon Uwan battered northern Philippines in November 2025, causing 25 deaths and displacing over 1.4 million people. The UN praised the country's preparedness but warned of more frequent powerful storms due to the climate crisis. At COP30, delegates discussed the urgent need for adaptation funding.

A new study reveals that El Niño weather events contributed to famines across Europe between 1500 and 1800, triggering some and prolonging others. Researchers found strong associations in central Europe and broader price impacts continent-wide. Modern agriculture, however, mitigates such risks today.

世界气象组织报告称,未来三个月出现弱拉尼娜影响天气和气候模式的概率为55%。尽管它对全球气温有暂时冷却作用,但许多地区仍预计将出现高于正常水平的温暖。这一评估源于2025年11月中旬观察到的边缘拉尼娜条件。

The Extraordinary El Niño Lottery Draw 2026, held on January 6 in Madrid, has distributed 770 million euros in prizes, with the first prize of 200,000 euros per ticket falling on number 06703, widely distributed across Spain. This draw, coinciding with Epiphany, has brought joy to localities affected by the DANA floods in Valencia and to Galician schoolchildren funding a trip. The second and third prizes have gone to 45875 and 32615, respectively.

A new analysis in Geophysical Research Letters shows Earth warming at ~0.36°C per decade since 2014—about double the prior rate of 0.18°C per decade—with 98% confidence after accounting for natural factors. Led by Stefan Rahmstorf, the study warns the Paris Agreement's 1.5°C limit could be breached by 2028, amid debates over short-term trends and data uncertainties.

A new analysis reveals that most studies on coastal vulnerability have underestimated current sea levels by an average of 24 to 27 centimetres because they overlooked key oceanographic factors. This methodological blind spot means that flooding and erosion risks will materialize sooner than previously projected, potentially affecting millions more people by 2100. Researchers from Wageningen University highlight the need for better integration of sea-level data in climate impact assessments.
