Environment pollution question ! =D?

Question

If trees exchange co2 for oxygen through their leaves and co2 is polluting our environment then in the autumn (or "fall" if your american") when most trees lose their leaves will the co2 levels be much higher in the atmosphere? I know it wont be massively higher becuase not all trees lose their leaves.

thanks.

Answer 1

Evergreen deciduous such as pines dominate northern areas.  And it is not just trees that do this, other plants also perform this process..

Answer 2

Yes.  You can see this in the CO2 concentrations in the atmosphere.  The "wiggles" in the monthly data here (you can find plots like this all over the internet, google "mauna loa co2 records" for lots more examples) are the trees and other plants growing and dying seasonally:

Answer 3

CO2 is nothing to worry about

the argument for it is that it has been rising rapidly since they began measuing 100 yrs ago in that time is has only risen .00032 %

that is not very much on the grand scale of things

Answer 4

Not all CO2 constantly stays in the atmosphere.A large part is precipitated back to earth.Some speculation has deemed this as the missing part of the carbon budget.It's a logical environmental process that has been happening for some time now.Low level precipitation is common during cooler weather.

Answer 5

I would think that it evens out globally.  When the trees lose their leaves in the northern hemisphere, the trees in the southern are sprouting.  Should balance out.
