Have you ever heard the term: thin winter air?
Yes there is less oxygen more co2 in the winter.
Most of the trees are found in the northern Hemisphere. (about three fourths) there’s always less CO2 in the air when it’s summer.

Also I have read something about ions effect on co2 levels from snow.
If any one has heard about that?

But these are only slight differences.

most Global oxygen is produced by oceanic phytoplankton and algae as well as from rain frorests, as Patrick pointed out.

Yeah, without trees, there wouldn't be oxygen. And without oxygen, people would die and soon human will become extinct.
