“A better appreciation of the brevity and exceptional character of the epoch of the fossil fuels can be gained if we view it in the perspective of a longer time span of human history than we have considered heretofore. In Fig. 10 the complete cycle of exploitation of the world’s total supply of fossil fuels, coal, and petroleum, is shown on a time scale extending from 5000 years in the past to 5000 years in the future. On such a scale, the Washington-Monument –like spike in the middle of this range, with a middle-80% spread of about three centuries, represents the period of exploitation of the fossil fuels in the much longer span of human history. Brief as this period is, having arisen, as we have seen, principally within the last century, it has already exercised one of the most disturbing influences ever experienced by the human species in its entire biological existence.”
