English: Records of radiocarbon production, A, as measured in bi-decadal samples of wood (Δ14C) in which the age of the sample is known from counting tree rings (Damon and Sonnett, 1991) for the period from 10,000 calendar years ago to the present. B, Residual (detrended; dashed lines) record of Δ14C in which the long-term secular variation trend has been removed.
