| Zusammenfassung |
| Climate changes in pan–Arctic regions and their impact on methane emissions from wetlands
are estimated based on simulations for the European and Asian parts of Russia with a
regional climate model developed at the A.I. Voeikov Main Geophysical Observatory. These
simulations are forced by the large–scale climate fields obtained in the SRES B1 and SRES
A2 runs. Methane fluxes from wetlands are diagnosed making use the modified
Christensen–Cox model.
For the late 20th century, total wetland CH4 emissions amount 8Â MtCH4/yr and
10Â MtCH4/yr for the European and Asian parts of Russia respectively. To the end of
the 21st century, these emissions increase up to 14Â MtCH4/yr and 17Â MtCH4/yr
correspondingly. The dominant mechanism of growth for the CH4 emission from wetlands
is a methane production enhancement in water filled soils due to increase of soil
temperature. |
