| Zusammenfassung |
| As carbon dioxide concentrations and temperatures rise, rates of decomposition processes and decay of peat are likely to increase while on the other hand, even quite small increases in productivity may compensate for this or even exceed it, especially in high latitude peatlands. A further complication in assessing whether peatlands will remain sinks or become sources of carbon is that peatlands emit quite large quantities of methane, fluxes which are linked to the water table position. Our project aims to assess the contribution of peatlands to the global carbon cycle over the past 1000 years by putting together a global dataset of high resolution C accumulation data together with regional scale peatland hydrology reconstructions. This data will then be used to calibrate models that simulate the distribution and growth of peatlands and of methane emissions on a global scale. |
