The reason we gave you a trivial example of how to falsify the claim is because the claim is trivial to falsify. The fact that it hasn't been falsified doesn't mean that it's true, just that it's amenable to scientific inquiry. Anything you might claim now is (at best) shifting the goalpost. However, if you'd like to submit another claim, I'd be happy to share my thoughts on it's falsifiability; maybe you have a less trivial one than "CO2 is a causal force in global warming" ?
