摘要

全球人为变暖导致的海洋变暖和相关的脱氧现象正在影响海洋生态系统。本文介绍了 Fröb 等人最近在《地球的未来》(2024 年)上发表的一项研究的背景,并对其中的关键见解提出了自己的观点。作者通过最先进的地球系统模型,采用历史和高排放情景模拟,利用生态生理学框架,量化温度和氧气如何共同限制海洋生物分布,从而检测海洋栖息地生存能力的突然和持续变化。变化点分析用于客观检测潜在海洋栖息地十年至数十年平均状态的变化。他们观察到,能够为对缺氧有积极敏感性的生态生物类型提供生存栖息地的海洋体积有所减少。其中约有一半的减少是突然发生的,从而凸显了海洋生物应对不断变化的环境的能力所面临的潜在风险。

Towards a Less Habitable Ocean

Ocean warming and associated deoxygenation caused by anthropogenic global warming are impacting marine ecosystems. This article contextualizes and provides perspectives on key insights from a recently published study by Fröb et al. in Earth's Future (2024). The authors employ historical and high-emission scenario simulations through a state-of-the-art Earth system model to detect abrupt and persistent changes in the viability of marine habitats by leveraging an ecophysiological framework that quantifies how temperature and oxygen jointly limit the distribution of life in the ocean for a number of ecophysiotypes. A changepoint analysis is used to objectively detect shifts in decadal to multi-decadal mean states in potential marine habitats. They observe a decrease in the ocean volume capable of providing viable habitats for those ecophysiotypes with positive sensitivity to hypoxia. About half of these decreases occur abruptly, thus highlighting potential risks on the capacity of marine organisms to cope with a changing environment.
