Extended Data Fig. 4: Relationship between climate- d18O correlations and long-term means (period 1920-1994) of precipitation sums (PPT), SPEI, water balance (WAB), mean temperature (Tmean), maximum temperature (Tmax) and VPD.
From: Recent human-induced atmospheric drying across Europe unprecedented in the last 400 years
Each point indicates a correlation coefficient calculated between a site δ18O chronology and the closest gridpoint climate dataset, plotted as a function of the nine selected climate long-term means (‘climatic regions’). R- and p-values in the legend indicate the significance of the relationship. Most p-values are above 0.05 which suggests independency of the correlation strength from the climatic region.
