The net impact of greenhouse gas emissions from degraded peatland environments on national Inventories and subsequent mitigation of such emissions has only been seriously considered within the last decade. Data on greenhouse gas emissions from special cases of peatland degradation, such as eroding peatlands, are particularly scarce. Here, we report the first eddy covariance-based monitoring of carbon dioxide (CO₂) emissions from an eroding Atlantic blanket bog. The CO₂ budget across the period July 2018–November 2019 was 147 (± 9) g C m⁻². For an annual budget that contained proportionally more of the extreme 2018 drought and heat wave, cumulative CO₂ emissions were nearly double (191 g C m⁻²) of that of an annual period without drought (106 g C m⁻²), suggesting that direct CO₂ emissions from eroded peatlands are at risk of increasing with projected changes in temperatures and precipitation due to global climate change. The results of this study are consistent with chamber-based and modelling studies that suggest degraded blanket bogs to be a net source of CO₂ to the atmosphere, and provide baseline data against which to assess future peatland restoration efforts in this region.

退化的泥炭地环境产生的温室气体排放对国家清单的净影响以及随后减少此类排放的影响只是在过去十年中才得到认真考虑。泥炭地退化的特殊情况（例如泥炭地侵蚀）产生的温室气体排放数据尤其稀缺。在这里，我们报告了第一个基于涡度协方差的对侵蚀大西洋毯状沼泽的二氧化碳 (CO ₂ ) 排放的监测。2018 年 7 月至 2019 年 11 月期间的 CO ₂预算为 147 (± 9) g C m ^-2。对于包含更多 2018 年极端干旱和热浪的年度预算，累积 CO ₂排放量几乎翻了一番（191 g C m ^-2) 与没有干旱的年度（106 g C m ^-2）相比，表明随着全球气候变化导致的温度和降水预计变化，来自侵蚀泥炭地的直接 CO _{2排放有增加的风险。}这项研究的结果与基于室的模型研究一致，这些研究表明退化的毯状沼泽是大气中 CO ₂的净来源，并提供了评估该地区未来泥炭地恢复工作的基线数据。
