Rethinking Anthropogenic CO₂: The Role of Natural Feedbacks, Adaptive Sinks, and Paleoclimate Perspectives

This preprint explores the current understanding of anthropogenic carbon dioxide (CO₂) contributions within the broader Earth system. While human activity remains the dominant driver of recent CO₂ increases, this work highlights the importance of integrating natural carbon sinks, biological feedbacks, and paleoclimate analogs—such as the Eocene epoch—into climate assessment. Key components include: • The role of rapid phytoplankton adaptation in marine carbon regulation • The underappreciated influence of permafrost carbon feedbacks • The scale of natural versus anthropogenic CO₂ fluxes • Lessons from deep-time climate systems This article is intended as a perspective and does not contradict mainstream climate science, but rather complements it by offering a system-level synthesis. This is a non-peer-reviewed preprint shared to encourage open scientific dialogue.
