Carbon and climate implications of rewetting a raised bog in Ireland
WILSON, David ; MACKIN, Francis ; TUOVINEN, Juha-Pekka ; et al.
2022
Dans cette étude, les flux de CO2, CH4 et d'oxyde nitreux (N2O) ont été mesurés pendant une période de 5 ans dans une ancienne tourbière haute dans l'ouest de l'Irlande, immédiatement après que le site ait été réhumidifié. Ont aussi été quantifiés et modélisés les flux provenant des zones drainées sur les marges et d'une zone ré-humidifiée avec une nappe phréatique élevée persistante pour fournir la base d'une estimation du bilan net de carbone de l'écosystème des deux écotopes.
Come rain, come shine: peatland carbon dynamics shift under extreme precipitation
BAREL, Janna M. ; MOULIA, Vincent ; HAMARD, Samuel ; SYTIUC, Anna ; JASSEY, Vincent E.J.

"Precipitation patterns are becoming increasingly extreme, particularly at northern latitudes. Current climate models predict that this trend will continue in the future. While droughts have been repeatedly studied in many ecosystems over the last decades, the consequences of increasingly intense, but less frequent rainfall events, on carbon (C) cycling are not well understood. At northern latitudes, peatlands store one third of the terrestrial carbon and their functioning is highly dependent on water. Shifts in rainfall regimes could disrupt peatland C dynamics and speed-up the rates of C loss. How will these immense stocks of C be able to withstand and recover from extreme rainfall? We tes...
Beyond CO2 equivalence: The impacts of methane on climate, ecosystems, and health
MAR, Kathleen A. ; UNGER, Charlotte ; WALDERDORFF, Ludmila ; BUTLER, Tim
2022
In this article we review the physical and chemical properties of methane (CH4) relevant to impacts on climate, ecosystems, and air pollution, and examine the extent to which this is reflected in climate and air pollution governance. Although CH4 is governed under the UNFCCC climate regime, its treatment there is limited to the ways in which it acts as a “CO2 equivalent” climate forcer on a 100-year time frame. The UNFCCC framework neglects the impacts that CH4 has on near-term climate, as well its impacts on human health and ecosystems, which are primarily mediated by methane’s role as a precursor to tropospheric ozone. Frameworks for air quality governance generally address tropospheric oz...
