Don't quote me on this, but if you think about, when it's winter in one part of the world, it's summer in another part, so it would all balance out. I guess you could say that it might increase locally, but I think air circulates too much and too quickly for that to happen.

Yes, the northern hemisphere winter does result in a jump in CO2 levels, in the same way, CO2 levels drop during the northern hemisphere spring and summer. (By far, most vegetation on land is in the Northern Hemisphere)
If you look at a graph of CO2 concentrations over time, it looks like sharks teeth with a slow upward trend overall. Over the last 45 years the average has risen from about 315ppm to about 380ppm - give or take. The amplitude of the annual fluctuation is on the order of 8-10ppm.

I liked Ethan's explanation about the seasonal cycle of atmospheric CO2. I just wanted to provide a link to graphic showing this seasonal cycle.

actually since 76% of the earths surface is covered in water, plankton and alge are the major 02 producers which means they are the major C02 consumers. So the changing of seasons has little effect.

Ethan's answer sounded reasonable.

less leaves = less co2.
