Extended Data Fig. 3: Simulated Seasonal δD Values Across Holocene Forcing Scenarios.
From: North Pacific ocean–atmosphere responses to Holocene and future warming drive Southwest US drought

Probability density plots of simulated δD seasonal precipitation for winter (DJF, blue-grey) and summer (JAS, orange-yellow) over the region including our two study locations (−107°W, −105°W, 35°N, 38°N) from i-CESM1.2. PDFs are shown for simulations with boundary conditions and forcings for: preindustrial (PI), mid-Holocene with preindustrial vegetation (MHPIveg), mid-Holocene with prescribed “Green Sahara” (GS), mid-Holocene with prescribed “Green Sahara” and high latitude vegetation (MHGS+NHveg)25.
