Please stop confusing inclusive assertions with exclusive

That is NOT my argument. My argument is that it has not
been proved beyond a reasonable doubt that man has any
primary effect on global warming. "Man-causing-global-
warming" is a religion, based on faith, IMHO. In fact,
it seems more likely that man's CO2 contribution to the
atmosphere will do nothing more than hasten the next
ice age.

Take a look at the slope of the C02 buildup of 120k
years ago just before the last ice age. It is very close
to the slope of the C02 buildup of today. There is evidence
that ~280 ppmv levels of C02 triggered ice ages 120k, 240k,
340k, and 440k years ago. That's about the level of CO2
today. There is reason to believe that another ice age
is poised to happen and the Man-causing-global-warming
religion will no doubt blame man for it.
