question

the ice ages / warming periods seem to be cyclic and corresponding co2 in the warming periods seems to be cyclic with the warming.

so is co2 cause or effect of the warming?....

Because if co2 was cause you would have to find some reason for the earth co2 level to go up all on its own

it’s more likely solar cycles causes glacial/ warm periods and co2 increase is an effect not a cause

But either way cyclically increasing co2 levels seem to be a natural thing in the environment

Yes. It is a lagging indicator versus a leading indicator.

A simple example is a carbonated drink. One is warm and one is cold. Shake them up and the warm one will give up the CO2 much more rapidly than the the cold one.

Agree, yet to find the scientific community tagging of CO2 owned by humanity versus mother nature.

If you will, it’s not that simple. Rising temperatures can be both a cause and a result of climate warming. Also, it might be a result of increased volcanism. Personally I feel that the key triggers are plate tectonics and most importantly solar output. However the man lesson seems to be that you can’t look at one thing in isolation. I haven’t even mentioned ocean currents and the are influential.
