How much O2 will be left?
Saturday, September 3rd, 2011
For those who haven’t noticed. There is currently a discussion about melting permafrost on Azimuth. If frozen soil is melted then usually greenhouse gases are going to be emitted. So in this context (comment on Azimuth) I was raising again the question to which extend the melting of permafrost could not only lead to more CO2 in the air but also induce a reagression of O2 (which may e.g. be due to a sudden expansion of aerobic organisms)*. If someone knows more about this then please comment here or on Azimuth.
*I am not sure, but I think such a mechanism may have led to the abort of a simulation for studying the colonization of Mars.
