Fig. 4: Historic and future projections of lake stratification phenology.
From: Phenological shifts in lake stratification under climate change
Temporal and spatial variations in a, b the onset and c, d the break-up of thermal stratification, as well as e, f the duration of the thermally stratified period. The temporal changes in lake stratification phenology are shown a, c, e from 1901 to 2099 under historic and future climate forcing (RCP 2.6, 6.0, 8.5). The thick lines show the average across all lake–climate models, and the shaded regions represent the standard deviation across the model ensemble. b, d, f show the spatial patterns in stratification phenology anomalies by the end of the twenty-first century (averaged over all years from 2070 to 2099) under RCP 8.5. Anomalies are quoted relative to the 1970–1999 base-period average.
