"Most of the gases emitted by the ocean return to the oceans."

No support given for this assertion. It's also possibly bogus.

I notice they also used averages from just a couple volcano's including a
couple that a relatively "clean".

We aren't talking about, say, a 30% difference here - we are talking
about man made sources being *150* times greater. Even if their
estimates were off by an order of magnitude, man made emissions would
still be 15 times greater.
