Proportion of predicted species’ range along the successive binarization threshold applied at 0.01 increments (see Methods for details) for the (a) baseline and (b) future periods. The lines and shade colors represent model settings (orange = coarse-resolution, green = fine-resolution). The future panels are divided by time period (2041–2070 and 2071–2100) and emission scenario (SSP1-2.6 and SSP5-8.5), while the filled envelopes represent the range of proportions based on four Global circulation models.
