      I was thinking the other day…..that whether or not the level of carbon dioxide would be lower in winter than in summer……coz green plants have no leaves (i.e. chloroplasts) to carry out photosynthesis in winter and hence less carbon dioxide would be taken in for photosynthesis.
      Correct me if I am wrong!
      Thx……

      I think you mean higher in winter, not lower. Sorry, I just noticed that. but that does make sense. I don’t know for sure that it would be, but the hypothesis is interesting. I would have to agree with you.

      Good thinking πŸ˜€

      Think hemispheres… What is the season in Australia? Beside most of the photosynthesis seems to be carried out by algae and rain forest (no seasonnality between the tropics).

      yea. That’s what I meant. Higher in winter that is! So you were saying, that you agreed with me?

      Have you seen canalon’s post??

      Yes, with the hemispheres it probably does even out. However, is there an equal amount of plants in both hemispheres that would be affected by seasons?

      Are you kidding me? We have cars that are left to warm up in the morning to compensate! πŸ˜†

      Don’t see what that has to do with Carbon Dioxide

      Might be his car takes CO2 and makes ethanol for fuel… πŸ˜† πŸ˜†

      ==================================

      The seasonal change is compensated as there will be opposite season in other hemisphear. And co2 is balanced.

      As a result, would there be LESS carbon dioxide in warmer countries (e.g. Australia) than in colder countries (e.g. UK)?

      Um…car emission gives of CO2….

      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.

      I thought there were more trees in the northern hemisphere!! Ok, cool.

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

      imagine a world without oxygen…….that would be tres tres triste………no life what so ever……
