Yes aggressively. Raising the average (I don't understand why you'd bring up noise when discussing average) temperature of the entire Earth by 1-2 degrees C in a period of 100 years, from 1 single organism is remarkable. Any why specify CO2 as if that's the only thing we're polluting with? What about methane? Remember when we disrupted the ozone layer? What about pollution with plastics, and industrial chemicals in land and water?
And don't forget that the Earth is more than willing to enter a negative feedback loop -- she will take that 1-2 degree increase in temperature and say "I heard you like warm weather, so I'm gonna release all this trapped methane and CO2 from my frozen parts and let you have it too."
