Yeah, keep believing, because, your agenda needs to believe,
in order to keep trying to get the ignorant to believe your version of "science".
So, tell me, which scientist or researcher has ever stood at the mouth of a volcano and measured the actual amount of CO2 emitted? I would say: NONE! What can't be measured, can only be guessed at, and, the guessing always favors the one who needs to make a point in his direction.
Try your beliefs when the science is not part of an agenda, and when your science is open to scrutiny and doesn't massage the data in order to fit your pre-defined results/conclusions.
