Mantas,
I think your whole premise that local CO2 has an affect on local weather makes no sense when you understand the mechanism of how CO2 warms the earth. The idea is that greenhouse gasses (and not just Co2) absorb energy in the infrared spectrum so they stop the earth from radiating some heat at night that would normally be radiated. This is not a local affect and is a cycle that happens every day and night. A good discussion of this can be found here
