Positive or negative? Seems like more tectonic movement causes more CO2? On the other hand biomass might get covered when a plate goes below another. I suppose this is a necessity for oil production?
Here is a link http://dilu.bol.ucla.edu/ . The relations seems complex. The PDF of the lecture yesterday is 55 MB and we haven't yet a way to transfer the file. This was mentioned in relation to astrobiology and tectonic plates and motion only occurs under narrow conditions for a planet.
