泥火山作用是一种丰富的全球性现象，富含流体的低密度沉积物在陆地和近海都突出。甲烷通常超过气相的90体积%，在泥丘就位期间和之后以高速率排放，并且以其高全球变暖潜能值（GWP）而闻名。对泥火山脱气的年度贡献的全面估计评估了泥火山作用对大气中温室气体积累的重要性。一阶估计较早，前人类活动量的甲烷释放通过泥火山进一步支持其对地球气候的深远影响，因为至少在古生代（570马）。
Mud volcanism is an abundant, global phenomenon whereby fluid-rich, low-density sediments extrude both on land and offshore. Methane, which generally exceeds 90 vol% of the gas phase, is emitted at high rates during and after emplacement of the mud domes and is known for its high global warming potential (GWP). This comprehensive estimate of the annual contribution of mud volcano degassing assesses the significance of mud volcanism for the accumulation of greenhouse gases in the atmosphere. A first-order estimate for the earlier, pre-anthropogenic volume of methane released through mud volcanoes further supports their profound effect on the Earth's climate since at least the Paleozoic (570 Ma).
