Dera Ismail Khan: then, now and by 2100
| Map | Climate zone | Compared with now |
|---|---|---|
| 1901 to 1930 | BWh Hot desert | Same as now |
| 1991 to 2020 (now) | BWh Hot desert | - |
| 2071 to 2099, SSP1-2.6 (low emissions) | BWh Hot desert | Same as now |
| 2071 to 2099, SSP2-4.5 (middle of the road) | BWh Hot desert | Same as now |
| 2071 to 2099, SSP5-8.5 (high emissions) | BWh Hot desert | Same as now |
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 Dera Ismail Khan in BWh in 2071 to 2099. The high-emissions scenario (SSP5-8.5) gives the same answer.
