Re: [Phys-l] Climate Change - Is it Controversial?

Either I'm stupid or you'all (except R. C.?) are missing the point.   
In the geo. past there was much  more plant mass which (was)  
sequestered (ing) the primordial CO2.  So by burning it now we are  
"going back" to the geological past, which means much warmer from the  
much greater CO2 concentration.  This is why deforestation is a  
concern in addition to burning ancient forest (jillions of years  
old)  Some coal seams contain plant fossils (incomplete  
metamorphosis).  That's how we know it was ferns, etc.  No C-14. of  
course.  Cl-36? may be a "dater isotope"?

bc puzzled.
