Yes, and the 11 year sunspot cycle has been a well documented
fact for thousands of years. Does puny man have any more
control over the 100K year CO2 cycle than he does over the
11 year sunspot cycle. Methinks you (and others) suffer
from delusions of grandeur. Why do you think the CO2 levels
*ALWAYS* drop after they reach ~280 ppmv? Do you think man
can do anything to block that ~100k year drop in CO2 levels?
