The Anthropocene is defined by marked acceleration in human-induced perturbations to the Earth system. Anthropogenic emissions of CO and other greenhouse gases to the atmosphere and attendant changes to the global carbon cycle are among the most profound and pervasive of these perturbations. Determining the magnitude, nature and pace of these carbon cycle changes is crucial for understanding the future climate that ecosystems and humanity will experience and need to respond to. This special issue illustrates the value of radiocarbon as a tool to shed important light on the nature, magnitude and pace of carbon cycle change. This article is part of the Theo Murphy meeting issue 'Radiocarbon in the Anthropocene'.
人类世的定义是人类对地球系统的扰动显著加速。人为向大气排放一氧化碳和其他温室气体以及随之而来的全球碳循环变化是这些扰动中最深刻和最普遍的。确定这些碳循环变化的幅度、性质和速度对于理解生态系统和人类将经历并需要应对的未来气候至关重要。本期特刊阐述了放射性碳作为一种工具的价值，它有助于深入了解碳循环变化的性质、幅度和速度。本文是西奥·墨菲会议特刊“人类世中的放射性碳”的一部分。
