“…Compounding concerns around liquid fuel supply, are concerns about reduced agricultural yield during an abrupt sunlight reduction scenario (ASRS) resulting from catastrophes such as climate altering volcanic eruption (eg, of magnitude equalling or exceeding that of the 1815 Tambora eruption (Wilson, Valler, et al, 2023)), or soot injected into the stratosphere from a nuclear war that produces a nuclear winter, cooling the planet and increasing the number of frost days (Coupe, Bardeen, Robock, & Toon, 2019; Jagermeyr et al, 2020; Xia et al, 2022). Such climate impacts might require reprioritisation of agricultural production resources (Wilson, Payne, & Boyd, 2023), to favour resilient foods (Rivers et al, 2022), in order to maintain the quantity of food needed for domestic consumption.…”
