a Yield change was attributed to specific climate change factors, including changes in growing degree days (ΔGDD), extreme degree days (ΔEDD), solar radiation (ΔSSR), and the ratio of precipitation to potential evapotranspiration (ΔRatio of Prcp to pET). The climate change-induced yield changes were calculated as the ensemble mean of seven climate models, weighted by gridded harvested areas. Box plot indicated median (black line), 25–75th percentiles (box), 5–95th percentiles (whiskers), and mean value (circle). b–e, Spatial distribution of climate drivers contributing to yield changes under the SSP585 scenario.
