Figure 4

Comparison of the solar modulation reconstruction37 (a) and the total solar irradiance (TSI) reconstruction36 (b) with the Cha2-GP5 δ18O composite record (c), the Ifoulki cave (IFK1) stalagmite δ18O record8 (d) and the tree-rings ScPDSI record12,13 (e). Blue shading indicates periods of low solar activity: Oort minimum (1010–1090 AD), Wolf minimum (1280–1350 AD), Spörer minimum (1450–1550 AD), Maunder minimum (1645–1715 AD) and the Dalton minimum (1790–1820 AD). Black arrows indicate peaks of low solar activity and their corresponding peaks of wet conditions in Morocco.
