Climate oscillations, such as El Niño/Southern Oscillation (ENSO), play a key role in global and regional crop yield variations. The authors analysed crop yield data in China from 1980 to 2017 and found that ENSO affects yield not only through local climate variability but also by driving migratory crop pest outbreaks, highlighting an overlooked pathway by which ENSO drives yield loss.
