In other words, just because both CO2 levels and temps rise, seemingly together, does not mean that one is causing the other to rise - a third factor (or factors) could be causing both to rise.

Yes, true, that's why I created the article and this discussion. Of course it's possible that there is another cause, but what is it, and why? The best explanation as I see it, and I don't want to repeat what I've already explained, is that CO2 levels are the root cause.

Even though, historically, CO2 levels lagged temp changes? See, that simply makes no sense. What was the cause of temp increases 100 years ago? 1000 years ago? 10,000? etc.

What was the cause at the end of the LIA when the temps began to rise? They've risen at essentially the same rate and continue to do so. Why is it that only the last 50 years or so of this continual rise is being claimed by Warmists to be caused by CO2? What you and the Warmists are unable to do so far is show that man's CO2 emissions have had any noticeable effect on what has been happening. While it could, the fact that the natural warming trend hasn't been affected that much clearly implies that whatever causes the climate to change, either warmer or cooler, continues to do so.

Instead of saying "Gee, I dunno what it could be, so I'll say it's CO2", why aren't these so called "climate scientists" working to determine what factors do effect our climate? Oh, wait - it is only the Warmist scientists who aren't looking for other causes - the real, honest climate scientists are looking for other causes.
