Extended Data Fig. 8: Temporal changes of reduction in global GPP (Pg C/year) associated with all droughts relative to the historical period of 1850-1999.
From: Increasing impacts of extreme droughts on vegetation productivity under climate change
The relative reductions were calculated on a model-specific basis, dividing GPP reduction (kg C/m2/year) over a specific period by that over the historical period. The grey horizontal dotted line shows the mean value during 2075–2099. The p-values were calculated to check if there is a significant difference between future period of 2075–2099 and historical period of 1850–1999 using the bootstrap sampling approach laid out in Supplementary Note 5.1.
