It isn't scrubbing and it isn't trees. You need to look a little closer at
the science that's coming out of all this study of global warming. The
vast majority of CO2 is stored elsewhere, and the problem is that that
natural capacity to absorb excess and store it is being depleted. And yes,
the vast majority of this is due to human emissions.

1) What percentage of annual CO2 production is human caused and what portion
is natural?

2) What are the short-term and long-term effect of CO2 concentrations?
