I don't think that waving away 'global warming' with "well it had to either go up or down" is very honest. If the temperature were going up by 0.001C a year there wouldn't be this kind of debate about it. Either way we've been burning coal and oil like mad since the middle of the 1800s, and that exhaust mass from combustion doesn't just disappear into the ether. It went somewhere. Where did it go? Add up all the spots it went (e.g. trees, chemical reactions with soil, in atmosphere, with the oceans, etc.). If you still have CO2 left over, then the Occam's answer is that it's still where you left it: In the atmosphere. Other conclusions require evidence to support.
