The level of CO2 in the atmosphere is approx 405 part per million or 0.000405%, with an ideal of 350ppm
The question is how much is mankind responsible for, and what effect this increase of 55 parts million has on climate if any.
The vulcanos in Iceland put significantly more pollutants into the atmosphere than mankind does, not that this is an argument for mankind to pollute,
The theory of anthropogenic climate change is a hypothesis, namely this is no uncontestible proof that makes it a fact, and a consensus of learned people does not change a hypothesis to a fact, although the popular press would like to suggest it does, the only thing that counts is uncontestible scientific proof, and that is notable by it's absence.
i don't know what your scientific credentials if any are, mine are somewhat sketchy, an MSc in Physics and Mathematics, but when I did my degree facts were proven ( beyond any doubt) not by consensus of interested parties.who may gain some advantage ( like research funding, or a plumb appointment)
