7. Estimates (Additional Resources 1) for emissions of methane to the atmosphere are given in the table below and the current atmospheric concentration is 1.834 ppmv. Calculate its residence time. Sources of atmospheric methane Million tonnes per year Wetlands and other natural sources 160 Fosil fuel related sources 100 Other anthropogenic sources of biological origin 275 There may be $10^{14}$ t of methane hydrate ($CH_4 \cdot 6H_2O$) in the permafrost below the ocean floors. If 1% of this were to melt per year, what would be the increased concentration of methane (ppmv $y^{-1}$) in the atmosphere neglecting any removal processes? What sinks for methane would play a role in reducing this concentration? 8. Recent work$^{11}$ has shown that the flux of methane released from fens in the boreal forest area
