Ultimately, if global warming proves to be a serious threat to the
planet; no doubt it will be possible to build some kind of industrial
facility which can suck out CO2 from the air at a fast industrial rate.
I haven't heard anyone propose this idea; I should build a pilot
"plant"; patent the idea, and when the crunch comes I'll be richer than

I'm no geologist, but I don't think most of the coal formed in peat
beds; but rather in vast shallow semi acidic swamps similar to the
Okefenokee of today. The vegetation grew very fast, sunk down into the
shallow water and only partially decayed.

They were very primitive forests; tree ferns, equisitum (sp?), etc. Not
our typical gymnosperms or angiosperms.
I've got a lot of geology books so I could look this stuff up if anyone
really wants to know. It's all well understood by geologists.
