Fig. 4: Attribution of ELI trends to land–atmosphere variables.
From: Widespread shift from ecosystem energy to water limitation with climate change
Colours indicate the variables that best predict the decadal ELI dynamics calculated using multivariate linear regression with a set of equally well-performing models, across which the most meaningful predictor is selected (Methods). Stippling indicates grid cells where only one linear model performs well (adjusted R2 > 0.5) and contains only a single explanatory variable. Grey colour denotes grid cells without any model with reliable performance (adjusted R2 < 0.5). Insets show the total fraction of warm land area controlled by respective variables (top) and the fraction of ELI trends controlled by incoming shortwave radiation per region of interest (bottom). This figure is created with the ggplot2 package and the country borders using the maptools package73,74.
