The 2071 to 2099 rows are model projections under three emissions scenarios, not forecasts. The 1901 to 1930 row is a reconstruction. All come from Beck et al. (2023).
Under the middle-of-the-road scenario (SSP2-4.5), the model keeps Saint Petersburg in Dfb in 2071 to 2099. Under the high-emissions scenario (SSP5-8.5) it is Cfa (humid subtropical).
