Peatland carbon is estimated as about 550-1000 Gt in northern latitudes   and >100 Gt in tropical regions . For both northern mid- and high-latitude and tropical peatlands, a shift from contemporary CO2 sinks to sources were simulated in high-warming scenarios . Due to the lack of large-scale modelling studies, there is low confidence for climate change impacts on peat carbon uptake and emissions. The largest risk to tropical peatlands is expected to arise from drainage and conversion to forestry or agriculture, which would outpace the impacts of climate change . The magnitude of possible carbon losses is uncertain, however, and depends strongly on socioeconomic scenarios .
