Fig. 1: Study sites and their hydrological responses.
From: Recent climate change has driven divergent hydrological shifts in high-latitude peatlands
Non-permafrost (a, c, e) and permafrost (b, d, f) sites are plotted separately. a, b Reconstructed hydrological response of 98 records since 1600 CE on the map of northern permafrost zones35. Literature-based five records are indicated by triangle symbol. c, d Reconstructed standardised water-table depths (WTDs) on the map of summer (June-July-August) temperature anomaly (°C). e, f Reconstructed WTDs on the map of summer precipitation anomaly (mm/day). WTDs, temperature and precipitation data presented in c–f are values calculated using (1963 to 2012 CE average) minus (1851 to 1900 CE average). 76 records that have data points for these two periods are shown. Temperature and precipitation data (ca. 2° latitude x 2° longitude grids) are from NOAA-ESRL and CIRES twentieth century Reanalysis (V2c)33. The coordinates of the study sites on the maps are adjusted using a ‘ring’ Points Displacement to avoid overlapping; the actual coordinates are in the center of each ring and can be found in the Supplementary Fig. 1 and Datasheet 1.
