I proposed holding charcoal as a carbon bank some time ago,

No, you were proposing taking what is normally left on the forest floor and using it as fuel, thus removing the elements from the local biosphere of the trees.

That CO2 has been there for quite a while too.

Really?   So you have data on how much CO2 was there to start and how much is there now?

I love arguing with the ignorant, it's so easy to look smart.

Go ahead, show us all how 'smart' you are.   Show the amout of CO2 to start with.

Then show the amount of oil to start with in tar sands and oil shale.

I'll be waiting.   Odds are you won't bother, because, well you have a history of non-delivery.

I really love it when stupid people show how poor their reading ability is, too.

You mean, like a forest fire "uses it" as fuel?  I've proposed a number of different things, quite a few of them having nothing to do with forests.
thus removing the elements from the local biosphere of the trees.
Wrong.  I've always supported replacement of the phosphorus and potash, either by returning them or substituting other fertilizer.

You really show your poor reading ability here, because I never said that.
Go ahead, show us all how 'smart' you are.   Show the amout of CO2 to start with.
I never said I knew that, I only said that what's there is millions of years old.  That and the rate of production puts a ceiling on the rate of leakage.

I don't expect you to comprehend this either.
