The quote from Cormac McCarthy's "Cities of the Plain" reflects the unpredictable nature of droughts, emphasizing that neither the environment nor people can foresee when these dry periods will occur or end. This uncertainty highlights the challenges faced by those dependent on natural resources, as they must adapt to the escalating chaos of nature's cycles.

Moreover, the statement suggests a broader existential theme, illustrating how life is filled with uncertainties. This unpredictability can lead to feelings of helplessness in both individuals and communities as they grapple with the effects of climate and circumstance beyond their control.
