The best argument AGAINST CO2 causing climate change?

I’ve been on the look-out for the best arguments why CO2 is NOT causing climate change. Here’s the best one I’ve found to date along with some counter-arguments and evidence. It looks at whether CO2 is saturated in the atmosphere and more CO2 will now make minimal additional impact on warming. We get into the science at a molecular level on this one!

The Mallen Baker Show is aimed at all people who see themselves as change makers, with commentary on issues and change movements with a particular focus on climate change and environment, social issues, free speech and corporate social responsibility.

UPDATE: Added reference to paper by Zhong & Haigh 2013' which covers the saturation topic directly
