From: No trends in spring and autumn phenology during the global warming hiatus
Spring and autumn temperature trends at 56 FLUXNET sites. The left plots are the spaghetti plots of spring (a) and autumn (b) temperature. The right plots are the number of sites with different significance level for spring temperature (c) and autumn temperature (d). All stands for the total number of sites with positive slope (or negative slope) regardless of significance level. p < 0.1 stands for the number of sites with positive slope (or negative slope) that was significant at p < 0.1. p < 0.05 stands for the number of sites with positive slope (or negative slope) that was significant at p < 0.05. The light gray background indicates the warming hiatus
