Figure 2. Histograms of significant periodicities present in the data and random walk simulations.

Figure 2

(A) All periodicities in the random walks over 90% false alarm level; (B) All periodicities in the proxy climate records over 90% false alarm level; (C) Highest power periodicities in the proxy climate records over 90% false alarm level; (D) Periodicities with a period ≤500 years in random walks over 90% false alarm level; (E) Periodicities with a period ≤500 years in the proxy climate records over 90% false alarm level; (F) Highest power periodicities in the proxy climate records over 90% false alarm level ≤500 years. Solar cycle bands commonly reported in palaeoclimate literature are illustrated.
