Fig. 2: Global distribution and trends of ecosystem water limitation.
From: Widespread shift from ecosystem energy to water limitation with climate change
a, Trend in the multimodel mean of ELI (dots indicate significance: P < 0.05 based on Kendall’s tau statistic). The dashed boxes indicate regions of interest to aid easier cross-comparisons with other maps. The top inset displays the fraction of the warm land area that is drying or wettening according to ELI trends (P < 0.05 is hued darker). The bottom inset displays area-weighted average ELI trends for regions with different tree fractions based on six CMIP6 models (Methods). b, Multimodel mean ELI between 1980 and 2100. c, Same as b but derived with air temperature (Ta) instead of incoming shortwave radiation anomalies. d, Timing of regime shift from energy limitation to water limitation as indicated by ELI values becoming positive. The inset shows the global time series of the water-limited fraction of the warm land area (Methods). This figure is created with the ggplot2 package and the country borders using the maptools package73,74.
