So the C14 Co2 was produced for about 10 years (55-65), and was absorbed by natural sinks over the next 30 years?
That most CO2 added to the atmosphere is absorbed by natural sinks is well known. Most of the natural and human-caused. But something is causing Co2 to gradually increase. The hypothesis is that this increase is due to human emissions changing the natural Co2 balance.
If it's not that, then what is it?
It cant be the rise in global temp as there hasn't been any for 17 years.
