Figure S10 Ensemble mean and standard deviation of the SI-x leaf trend and departure of each model from the ensemble mean. Panels (1) and (2): mean (1) and standard deviation (2) of trends in spring onset timing as indicated by SI-x leaf across the first member of the 26 CMIP6 models during the 1981-2014 historical period. Panels (3-28): differences between each model trend and the ensemble mean. Panels (29-30): differences between the two observation-based first leaf trends and the model ensemble mean.
