Human production is around 3% of annual planetary CO2 production.

Very good!!

Follow-up: What is the most common greeenhouse gas and what is the breakdown
on human vs. natural sources?

Water vapor is the most common greenhouse gas. In fact, the greenhouse effect
is necessary for life as we know it in the first place. Without solar
energy being retained by H2O, CO2 and other gases, the Earth would quite
probably be rather frigid (although, if there was no water, it wouldn't
be icy of course!)

The human effect in the grand picture isn't that big (the Earth won't
turn into another Venus) but that's not to say that it won't be
significant. It's not necessary to "destroy civilization" either to have
less effect on the atmosphere. However, there's very strong evidence
(overwhelmingly strong) that the current increase in CO2 concentrations
is caused by us.

Yes, with a rather large delay; IOW, warming CAUSES CO2.
