Reconstructed April–June (AMJ) precipitation totals (top) and summer (June–August) temperature anomalies (bottom) for central Europe with respect to 1901–2000. Error bars are ±1 RMSE (Root-Mean Square Error) for the calibration periods. Black lines show independent precipitation and temperature reconstructions from Germany (Büntgen et al. 2010) and Switzerland (Büntgen et al. 2006). Bold lines are 60-year low-pass filters. Periods of demographic expansion, economic prosperity and societal stability are noted, as are periods of political turmoil, cultural change and population instability. Büntgen et al. (2011b)
