Understanding past, present, and future peatland responses to natural and anthropogenic drivers of change
Session ID#: 79617
Session Description:
Peatlands have played a key role in the global carbon cycle during the Holocene and previous interglacials/interstadials, as net long-term atmospheric sinks for carbon dioxide and substantial sources of methane. Recently, an increasing amount of observational, experimental, and modeling work has been put towards assessing the sensitivity of peatlands to changing climates and the fate of their large carbon stocks under warmer temperature regimes. There has been an effort to expand current knowledge to the tropics, sub-tropics, and temperate zones, where peatlands are abundant, and where humans are major drivers of change. For this PAGES / C-PEAT session, we invite the broad peatland community to present their work on past, present, and future peatland responses to natural and anthropogenic disturbance, including but not limited to: lab and field experiments, synthesis work, flux measurements, peat-based paleoclimatic records or new peat-based proxy development, and process-based or large-scale simulations.
