摘要:

气候变化增加了极端天气气候事件发生的范围、频率和强度,带来巨大的经济损失。尽管现有归因研究量化了人类活动导致的气候变化对极端事件发生概率的贡献,但气候变化对极端事件经济损失的贡献尚不明确,难以有效支撑适应政策的制定。文中基于极端事件归因研究的最新进展及多区域投入产出模型,全面核算了我国各省极端事件的直接和间接经济损失,对损失进行归因分析,并识别了重点适应部门和地区。研究发现,在中国极端事件造成的直接经济损失中,约有27%(约798亿元)可归因于人类活动导致的气候变化。这部分归因损失经由经济系统传导和放大,进一步造成了约911亿元的间接经济损失。其中,制造业和农业是最主要的承灾部门,未受直接影响的金融房地产、批发零售以及商务服务业也受到较大损失。

Abstract:

Climate change has amplified the range, frequency, and intensity of extreme weather events, leading to substantial economic losses. While existing attribution studies have quantified the role of anthropogenic climate change in increasing the probability of such events, its contribution to the resulting economic losses remains poorly understood. This knowledge gap hinders the development of effective adaptation policies. Based on the latest advances in extreme event attribution research, a multi-regional input-output model was employed to evaluate both direct and indirect economic losses from extreme events across China’s provinces. The portion of these losses attributable to climate change was quantified and key adaptation priorities were identified by sector and region. Findings indicate that extreme events attributed to anthropogenic climate change result in average annual direct and indirect losses of approximately CNY 80 billion and CNY 91 billion yuan, respectively, accounting for around 27% of disaster-related losses. The manufacturing and agriculture sectors are identified as the most affected, while industries such as finance, real estate, wholesale and retail, and business services, though not directly impacted, also incur significant losses.

Key words: Extreme weather and climate events, Loss and damage, Impact attribution, Climate change adaptation, Multi-regional input-output model
