Modelling upland peat carbon:past present and futureIf only...carbon molecules could bite!“Thinking big, working small and modelling in between”Dr Andreas <strong>Heinemeyer</strong> andreas.heinemeyer@york.ac.ukUniversity of York, Environment Department
Current models & peatCurrently, we cannot adequately predict peatland soil C stocks and C dynamicsFrom: ISLSCP IIFrom: SDGVM(kg C m -2 )Most current models lack:• Holocene peat accumulation• total peat column decomposition• peat depth dynamics• dynamic water table• vegetation feedbacks• topography effects~4.6 Mt C lacking a pedogenesis concept
