We appreciate the opportunity to respond to Hogg et al.’s critique of HDK182. We consider that neither the arguments nor the additional data presented by Hogg et al. provides a basis for rejecting our hypothesis of magmatic carbon bias in proximal 14C ages for the Taupo eruption. Hogg et al. focus on the wiggle match and Kaipo Bog dates out of > 40 data points, whereas our paper focused on the whole data set and trends within it. The date series as a whole reveal an undeniable pattern of “younging” with distance, irrespective of the suggested minor adjustments in the measurements included or excluded.
