Regional contributions to the trend reversal after 2009. a Slope change ratio in different regions from various datasets. The short vertical black line is the mean value of the 6 datasets (colored dots). A positive (negative) value of Rsc indicates that this region strengthens (weakens) the trend reversal after the breakpoint. b Removal of pairs of regions that leads to the insignificance (p > 0.1) or disappearance of the trend reversal. Squares with the same hatch are one removal of 2-region combination
