In a recent paper published in Environmental Research Letters, researchers at Pennsylvania State University examined how nuclear war might disrupt food security worldwide, focusing specifically on the global production of corn, the most produced grain crop in the world. First, the “best-case scenario,” a regional nuclear war, would release enough soot into the atmosphere to reduce annual corn production by 7%—which, to be clear, would severely impact the global food system, study lead author and meteorologist Yuning Shi explained in a press release. That wasn’t all; radiation damage “would peak in years 8 and 9” following the initial detonation of the bomb, causing an additional 7% decrease in corn yields, according to the paper.
