Peak Δ14C regional response (colour code is shown on the right) over land to the ESPE of 12350 BC (model experiment GW). The central panel depicts the geographical distribution, while the panel on the left shows the zonal mean (over land) of the results from the middle panel. -- Earth and Planetary Science Letters
