A weak long-term correlation between atmospheric CO2 levels and terrestrial warming is one of the basic "proofs" that Warmists offer for their claims. On that reasoning the fact that the concentration of argon in ice core bubbles goes up and down alongside CO2 over the long term should "prove" that argon (another atmospheric gas) causes warming too. Or maybe CO2 causes argon to emerge from somewhere! See the graph below:
"BP" stands for "Before the Present". Argon in the period above is quite a close correlate with CO2. That both argon and CO2 levels might be an EFFECT of warming rather than vice versa must not be mentioned, of course. Everyone knows how the fizz fizzles away as a Pepsi gets warm. Likewise, since the ocean contains vast reserves of CO2, anyone can easily grasp what happens when the ocean gets warm. The scales should fall off of people's eyes when that simple fact is explained.
