Using peatland archives to test paleoclimate hypotheses

Figure 2: Focus Interval III (cal a AD 800–1800) of the ACCROTELM project, showing proxy-climate data from the Danish bog site: Blue line = normalized testate amoebae water table reconstruction (inverted); Green dashed line = plant macrofossil Dupont wetness index; Gray line = normalized C relative production rate (q). Arrows indicate start of significant rises in water table. Historical solar minima are indicated. Figure adapted from Mauquoy et al., 2008. For further discussion of solar-climate relationships in peat records, see van Geel and Mauquoy, this issue.
