Not sure I understand your question.

Yup. You’ve explained the theory very well.

100%

LOL. The annual carbon cycle is ~750 gigatones.

Sorry, Noo. I was speaking of aggregate natural greenhouse gas emissions versus those from human activity.

100%.

To your point:

“the hottest, climatically wackiest, year on record ”
