These calculations are based on carbon burning, but it looks like it does
not account for a really large source of carbon going into the atmosphere:
the clearing of forest lands for agriculture.  If the calcs did account for
deforestation, Brazil should show up much more on the list of CO2

A forest draws down a lot of carbon.  Do the calcs yourself: go to the
nearest forest, measure the distance between a number of adjacent trees,
estimate or measure their height and diameter at the base, assume them to be
roughly conic, calculate their volume (~1/12*pi*d^2*h) and assume about 800
kg per m^3 is carbon.  Whenever I do this, I find we can draw down as much
carbon as we want, and get some really cool forests in the deal, if we just
supply the continental interiors with fresh water.
