Photoperiods and changes in the GDD5 ≥ 1200 area between current conditions and the average projections for 2095–2099. The gray region describes the inter-model variability for the projections calculated by the seven GCMs. The dotted lines represent the maximum and minimum day length, and the continuous line indicates the average day length for May through September at the different latitudes.
