I think anyone with even a passing understanding of the data can summarily dismiss your "argument", which is full of logical fallacies.
Atmospheric CO2 has gone from about 280 ppm pre-Industrial Revolution to 415 today. Yes, figuring out all the impacts and feedback loops is incredibly difficult, but it requires only a passing understanding of physics to understand how being on track to doubling the primary greenhouse gas in the atmosphere will result in a massively warmer planet.
