From: No trends in spring and autumn phenology during the global warming hiatus
Phenology trends at 56 FLUXNET sites with at least 7 years of high-quality data. The left plots are the spaghetti plots of SOS (a) and EOS (c). The right plots illustrate the number of sites with different SOS (b) and EOS (d) trends at different significance. Green bars indicate the number of sites with advanced SOS (b) or delayed EOS (d), while the brown bars indicate the number of sites with delayed SOS (b) or advanced EOS (d). All stands for the total number of sites with positive slope (or negative slope) regardless of statistical significance. 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 in a and c indicate the warming hiatus
