Actually, it's all about physics and energy budget. Meddling with one of the components of our beloved greenhouse effect does impact the energy budget, raising temperatures at the ground, ocean and lower atmosphere. The effects of antropogenic CO2 are NOT insignificant.

Who said antropogenic CO2 was "unnatural", by the way? It's natural as heck. It has just been conveniently stacked away by geology for millions and millions of years.
