Humanity has an impact on all the things you mention (you forgot chemtrails or geo engineering in you list BTW)
but I believe climate has more to do with with solar influences rather than man's impact - the sun has been around for a while and so has climate change
Man may be able to affect some weather patterns - which it has done with the help of HAARP - but "climate change" is just a convenient tool which has made a few people and incredibile amount of money at the expense of the masses.
