In his 2005 bestseller Collapse: How Societies Choose to Fail or Succeed, geographer Jared Diamond focused on past civilizations that confronted severe climate shocks, either adapting and surviving or failing to adapt and disintegrating. Among those were the Puebloan culture of Chaco Canyon, New Mexico, the ancient Mayan civilization of Mesoamerica, and the Viking settlers of Greenland. Such societies, having achieved great success, imploded when their governing elites failed to adopt new survival mechanisms to face radically changing climate conditions. …. Precursors of Collapse When do we know that a civilization is on the verge of collapse? In his now almost 20-year-old classic, Diamond identified three key indicators or precursors of imminent dissolution: a persistent pattern of environmental change for the worse like long-lasting droughts; signs that existing modes of agriculture or industrial production were aggravating the crisis; and an elite failure to abandon harmful practices and adopt new means of production. At some point, a critical threshold is crossed and collapse invariably follows. Today, it’s hard to avoid indications that all three of those thresholds are being crossed. To begin with, on a planetary basis, the environmental impacts of climate change are now unavoidable and worsening by the year. To take just one among innumerable global examples, the drought afflicting the American West has now persisted for more than two decades, leading scientists to label it a “megadrought” exceeding all recorded regional dry spells in breadth and severity. As of August 2021, 99% of the United States west of the Rockies was in drought, something for which there is no modern precedent. The recent record heat waves in the region have only emphasized this grim reality. https://scheerpost.com/2023/08/18/michael-klare-collapse-2-0/ |
