Prior to this period, the two curves appear not to show similar solar cycle variations, which is likely due to regional
climatic effects (Usoskin et al. 2009) leading to strong
fluctuations of the 10Be deposition (Pedro et al. 2006, 2011).
The
climatic glacial mode may develop rapidly, but there is a lag
