Fossil pollen records used (for details and references, see Supplementary Table 1) are grouped in three clusters: Midwest (squares), Great Lakes (triangles), and Northeast (diamonds). The corresponding regions used to extract results from climate model simulations are indicated with white lines. The dashed line indicates the geographic span of the pollen−climate calibration dataset55 (2419 surface pollen samples).
