Crutzen (1974) and Crutzen and Ehhalt (1977) presented two key papers in Ambio that in Ambioexemplify how science first revealed to humankind the potential for damage to our ozone shield in the Anthropocene. Crutzen's (1974) review is a sweeping summary of the risks to the ozone layer from supersonic aircraft, chlorofluorocarbons, as well as nuclear weapons testing and nuclear war. Crutzen and Ehhalt (1977) described how the nitrous oxide produced from fertilizers could pose another threat to the stability of the stratospheric ozone layer. The two papers are part of a body of influential scientific work that led to the pioneering Montreal Protocol to Protect the Earth's Ozone Layer to phase out production of chlorofluorocarbons (in 1987), as well as national decisions that slowed or stopped production of supersonic planes (in the 1970s). They remain guideposts today for ongoing international negotiations regarding reducing emissions from fertilizer and limiting nuclear testing.
克鲁岑（1974）和克鲁岑和埃哈尔特（1977）在《AMBIO》杂志上发表了两篇重要论文，这些论文首次向人类揭示了在人类世，我们的臭氧层可能受到破坏的潜在风险。克鲁岑（1974）的综述全面概述了超音速飞机、氯氟烃以及核武器试验和核战争对臭氧层的危害。克鲁岑和埃哈尔特（1977）描述了肥料产生的一氧化二氮如何对平流层臭氧层的稳定性构成另一种威胁。这两篇论文是一系列有影响力的科学工作的一部分，这些工作促成了开创性的《蒙特利尔议定书》，以逐步淘汰氯氟烃的生产（1987 年），以及各国决定放缓或停止超音速飞机的生产（20 世纪 70 年代）。这些论文至今仍是正在进行的减少肥料排放和限制核试验的国际谈判的指导方针。
