I'm well aware of your position on this. I'm not gonna get in a whole thing again, but there's one glaring inaccuracy in your posts in this thread:
.04% has nothing to do with "our contribution." CO2 currently makes up .04% of the entire atmosphere. We've increased that concentration by about 47% since the industrial revolution.
Part Two: Satellites from NASA and other space agencies are revealing surprising new insights into atmospheric carbon dioxide, the principal human-produced driver of climate change.

Anticipating your next point, so no need to make it (or at least so I don't need to respond to it): "but .04% is barely anything!!!!!!!!!" True, but not particularly relevant. .00001% of lead in your blood is dangerous.

It's not the raw percentage that matters, it's how much effect that percentage has according to the properties of the material in question.
And I'll stipulate that you don't think CO2 causes warming anyway so it shouldn't matter if it increases, as you've stated elsewhere in this thread, so no need to respond with that, either. Although, your comment about that...
...is basically a description of how the greenhouse effect works. CO2 collects heat and releases it "to the atmosphere" as you say, which, of course, would warm the atmosphere, right? Isn't a warming atmosphere what global warming is all about? I'm presuming, though, that you meant to say it radiates that heat back into space. This is, of course, must be why Venus (atmosphere 96% CO2) is so cold relative to what it should be based on it's distance from the sun...
As I said to begin the post, we've argued this out a bunch already, so don't expect any more responses from me.
