I have a “Yeah but....” question
If the earth absorbes 55% of the CO2 - in the plants and ocean.......how much of it is permanent and how much is not (later re-emitted after decay?)
I presume what they are saying here is the entire 55% is permanent???
Does it really matter? ALL carbon on the earth is here. Any that is ‘locked up’ in oil, trees, natural gas, biomass, etc was once part of the atmosphere and its cycles. We can put no carbon back into the atmosphere that wasn;t once there to begin with at some point.
Carbon in the atmosphere is self regulating in a band that has and will vary over time, depending on so many othe rvariables, that ‘control’ is just a vapor of an idea, much less a possibility. So, if one is concerned about ‘too much CO2” in the air, I would ask, “What is the ‘normal’ concentration for our planet, being as it has varied from highs and lows. What is good? What is bad? Why? And most important, WHAT CAN WE EVEN DO ABOUT IT? It’s like peeing in Lake Superior and worrying that you ‘warmed it up’.
