Historic and future projections of globally averaged lake surface-water temperature anomalies (relative to the global temporal average of the pre-industrial control simulation). The temporal changes in lake-surface temperature anomalies are shown from 1900 to 2100 under historic (1900–2005) and future (2006 –2100) climate forcing (Representative Concentration Pathway [RCP] 2.6, 6.0, 8.5). For comparison the model projections are also shown from 1900 to 2100 for the pre-industrial climate, where the influence of anthropogenic greenhouse gases is omitted. For simplicity, the uncertainties for each dataset are not shown.
