Here is one site.. Atmospheric Gases
ergo...CO2 is a trace gas and it you read up on it humans create a small percent(.04%) of that trace. |
I didn't say co2 was not a trace gas, it is.
To expand on what I did say - 25% of the co2 in the atmosphere today is due to human activity over the last 250 years. The addition from human activity each year is small, but it accumulates over time.
