Fig. 4

The blue symbols are records with the de Vries cycle, while the greens show the ones with other solar-related cycles. Hollow symbols indicate records without solar-related cycles. Circles and rectangles indicate speleothem δ18O records covering Holocene and last glacial periods, respectively. Compiled TT, TT-3 and TT-5 records are all marked in red.
