Methane on the Move: Quantifying Natural Greenhouse Gas Emissions over Geological Time in the Orange Basin, South Africa

In the assessment of past, present and future global climate the contribution of natural greenhouse gas emissions has been largely disregarded. Our studies in the Orange Basin, South Africa indicate a highly variable rate of methane emission from the basin to the hydro- and atmosphere through geologic time. In order to understand the interactions between sedimentary basin evolution in time and space and Earth´s climate a global assessment of thermogenic methane emissions is required.
