I've tried to estimate the all-inclusive human created CO2 and NOx,
and it seems to be worth at least 100 billion tonnes/year (roughly
14.4 tonnes per human), and otherwise it could easily be worth a
trillion tonnes per year (144 tonnes per human). What's your best all-
inclusive swag?

1. Scientific Wild Ass Guess.
2. opinions, or judgements, about
something with less evidence than would make the opinion certain,
but more than a simple opinion with no factual basis. -
3. making a guess with some information, but not enough to
make a clear and certain determination.

Brad, try again, you are swaggering, uselessly, as usual.
But, thanks for the laughs... ahahahanson
