Fig. 4: Estimated annual global RS.
From: Temporal changes in global soil respiration since 1987
Slopes and significances of linear regressions between annual global RS from 1000 Monte Carlo trials and year are shown. Regression lines of RS for the year in 1987–1998 and 1999–2014 are shown in red. The gray region denotes the standard deviations of annual global RS from Monte Carlo simulations. The filled blue area denotes the hiatus period of global warming (i.e., 1999–2014).
