Figure 1 (IMAGE) Institute for Basic Science Caption Schematic illustration of no-analogue lake water temperature conditions. The black curve denotes simulated mean water temperature from 100 computer model simulations, responding to external forcings (volcanos, aerosols, greenhouse gas concentrations), and grey shading indicates the range of naturally occurring lake temperature variations.
