The question is which is the cause and which is the effect? And by how much?

Have they ruled out that that increased temperatures might cause C02?

Well, clearly the factor that lags behind is not the causal one.
That would kind of stand the notion of linear time on its head.

See my previous post. An increase of global temperature causes about 10ppm rise in CO2, maybe a bit more. That’s what would have happened as we warmed from the Little Ice Age to now. Instead there has been over 110 ppm rise in CO2 and still rising 2-3 ppm per year. Temperature is not pulling CO2 up anymore, CO2 is rising because we are releasing it.
