Which amounts to about 1 percent of the total CO2 in the atmosphere,

If, as you suggest, we are putting so much CO2 into the atmosphere
that the total increases by 1% per year that adds up pretty fast,

doesn't
it?

Um, he said, 1% of the total. Not 1% per year extra.

And adding 1% of the total, every year, is different from 1% per year extra,
exactly how?

Let's not lose site of the fact that the earth is not an open-cycle
system. CO2 is added and subtracted due to photosynthesis and other
mechanisms. Those processes themselves are complex, closed-loop systems,
thus making a purely "addition-driven" computation show only part of the
equation.


The biggest uncertainty seems to be in the ocean's capacity to remove
carbon dioxide from the atmosphe

Here's an interesting discussion of why that matters:
