Taking the pulse of the Sun during the Holocene by joint analysis of C-14 and Be-10
We have studied solar variations during the Holocene (i.e., last similar to 11,700 yr) by combining a new model of the Earth's dipole moment with C-14 data from the IntCal04 record and 10 Be data from the GRIP ice core. Joint spectral analysis of the two nuclide records suggests that the periodic behavior of the Sun was particularly pronounced between 6000-4500 yr BP and 3000-2000 yr BP, with domi
