No, just that it shouldn't be called "pollution" merely because it contributes to the greenhouse effect.
The total greenhouse effect on the Earth's surface is about 33°C. Even if you believe the current slight warming trend is mainly due to additional CO2 in the atmosphere, that does not magically transform the gas from a naturally occurring atmospheric gas to "pollution".
We are the 99%. A better world is possible.
