"Mate, there are "scientific papers" on both sides of the argument"
Not really. Can you point to any peer-reviewed research (i.e. not some crank blogger in a basement) saying CO2 has not/does not cause global warming?
The evidence in favour of CO2 causing significant global warming is now as strong as that pointing towards the existence of the Higgs Boson - which, too, is taken as uncontroversial fact in the scientific world.
Literally the only people saying CO2 doesn't cause global warming are fringe ideologues and conspiracy theorists outside the relevant scientific community.
