Carbon cycle simulations of deglacial mobilization of pre-aged terrestrial carbon from degrading permafrost

Carbon cycle model simulations using the box model BICYCLE to describe the effect of CO2 release from permafrost thaw during Termination 1. Contains:1) assumed forcing (CO2 released, D14C signature of released CO2),2) simulated changes in atmospheric CO2 and D14C for Termination 1 (18-10 cal yr BP) and with additional results on D14C (considering the background trend) for the CO2 peak around 14.6 cal yr BP (15-14 cal yr BP).
