Sure. The numbers are big. But so are the numbers they
are compared to. Once people start talking about livestock
being responsible for 20-30% of nation-wide emissions of
greenhouse gasses, these numbers start to come into
perspective: There are far fewer large mammals in the world
today than only a couple of centuries ago. These emissions
are lost in the balance, and counter significant parts
of the CO2 emissions.

And, as always: Until the impacts of a variable sun on the
variations in climate are fully understood and accounted for,
any statement relating to CO2 or other gasses and climate
variations, is purely speculative.
