Extended Data Fig. 1: Proxy and Model Precipitation Changes in the Mid-Holocene.
From: North Pacific ocean–atmosphere responses to Holocene and future warming drive Southwest US drought
Locations of sites from this study (stars: 1- Hunters Lake, 2- Stewart Bog) and synthesized proxy hydroclimate data (symbols) compared against simulated winter (DJF) precipitation (shading) from the ensemble of mid-Holocene experiments with (a) preindustrial vegetation (from PMIP3) and with (b) prescribed 6 ka vegetation (this study). Symbols indicate the proxy type: δ18O (circles), pollen transfer functions (diamonds), lake level (triangles), lake sediment (squares), and others (thin diamonds). The isotope record from 3-Leviathan Cave is indicated with a yellow circle. Stippling indicates where the majority of models agree (a: 8/15; b: 5/8). The red box indicates the area used to calculate changes in precipitation in the Southwest US, which is the same as in ref. 8.
