I’m not saying that it is bad. Certainly at some point an increase in CO2 would indeed be a bad thing, though I suspect we are far below that point now.
But the paragraph I cited was indeed malarkey. Nothing he mentions increases CO2 net, except fossil fuel burning. As you say, this merely returns previously stored C to the atmosphere, but it does indeed raise CO2. The others do not. Lumping them together is either an ignorant mistake or an intentional attempt to deceive the reader.
Your clarification is exactlty what I had already read into what posted previously. We are on the same page.
