  1. The values indicate the fraction of site in the related category to all sites, averaged by the five general circulation models, including GFDL-ESM4, IPSL-CM6A-LR, MPI-ESM1-2-HR, MRI-ESM2.0, and UKESM1.0-LL. ‘+’ denotes positive changes, and the ‘−’ denotes negative changes. ‘|SD + | > |MY + |’ denotes the relative value of increase in yield SD is greater than that in the mean yield.
