Re the issue of biomass influences on CO2 levels, if you look at the
chart of measured atmospheric CO2 from Mauna Loa:
you can see that the summer-to-winter difference is fairly substantial.
It's equivalent to about five years of CO2 increase (i.e. eyeballing the
chart it is about 5 years from a summer peak to a matching winter low).
Now, I don't know whether biomass changes are primarily responsible for
this variation. I could imagine that temperature and sunlight variations
could have other effects as well. I haven't tried to research it.
But it is definitely a noticeable effect.
