Figure 6.Differences in near-surface temperature (in °C, left figure) and air pressure at sea level (SLP in hPa, right figure) for boreal summer (June, July, August) between mid-Holocene climate 6000 years ago and pre-industrial climate around 1850ce (Ganopolski et al., 1998). This figure has been produced by Andrey Ganopolski using CLIMBER 2.4 with the same boundary conditions as in (Ganopolski et al., 1998).
