Periods of large igneous province (LIP) magmatism have shaped Earth’s biological and climatic history, causing major climatic shifts and biological reorganizations. The vegetation response to LIP-induced perturbations may affect the efficiency of the carbon-climate regulation system and the post-LIP climate evolution. Using an eco-evolutionary vegetation model, we demonstrate here that the vegetation’s climate adaptation capacity, through biological evolution and geographic dispersal, is a major determinant of the severity and longevity of LIP-induced hyperthermals and can promote the emergence of a new climatic steady state. Proxy-based temperature reconstructions of the Permian-Triassic, Triassic-Jurassic, and Paleocene-Eocene hyperthermals match the modeled trajectories of bioclimatic disturbance and recovery. We conclude that biological vegetation dynamics shape the multimillion-year Earth system response to sudden carbon degassing and global warming episodes.

生物地理气候敏感性控制地球系统对大型火成岩省碳脱气的响应


大火成岩省（LIP）岩浆作用时期塑造了地球的生物和气候历史，导致重大的气候变化和生物重组。植被对 LIP 引起的扰动的响应可能会影响碳气候调节系统的效率和 LIP 后的气候演变。使用生态进化植被模型，我们在这里证明植被通过生物进化和地理扩散的气候适应能力是LIP引起的高温的严重程度和寿命的主要决定因素，并且可以促进新的气候稳定状态的出现。二叠纪-三叠纪、三叠纪-侏罗纪和古新世-始新世高温热带的基于代理的温度重建与生物气候扰动和恢复的建模轨迹相匹配。我们得出的结论是，生物植被动态塑造了数百万年的地球系统对突然的碳脱气和全球变暖事件的反应。
