Atmospheric carbon dioxide derives from multiple natural sources including volcanic outgassing, the combustion of organic matter, and the respiration processes of living aerobic organisms; man - made sources of carbon dioxide come mainly from the burning of various fossil fuels for power generation and transport use.
Further calculations by Catling and his team conclude that no abiotic methane sources on a rocky planet could produce enough of the gas to counteract this process — whether it is volcanic outgassing from a planet's interior, chemical reactions in hydrothermal vents, even asteroid impacts.
«We've got a spacecraft on the way to Ceres, so we don't have to wait long before getting more context on this intriguing result, right from the source itself,» said Carol Raymond, the deputy principal investigator for Dawn at NASA's Jet Propulsion Laboratory in Pasadena, Calif. «Dawn will map the geology and chemistry of the surface in high resolution, revealing the processes that drive the outgassing activity.»
Melting permafrost outgasses CO2 and methane, and the decrease in sea ice allows oceanic CO2 to mix back into the atmosphere; taken together, these processes greatly amplify the effect of increased sunlight, driving a relatively rapid exodus from the ice age.
CO2 (ocean outgassing etc) is an effect, possibly a positive feedback but remember that a positive feedback still acts positively when the initial process reverses.
I spent years in semiconductor processing using ultra-high vacuum equipment and the concept of outgassing is crucial to every aspect of growth.
Some of that will be due to the physical ocean outgassing and of course some of that is due to biotic processes.
«All these processes give a taste of the complex interaction between sea ice, biological productivity, and deep water upwelling as mechanisms controlling CO2 outgassing in the Southern Ocean, particularly at the Antarctic Polar Front, where they are strongly coupled.»
