Did you ever wonder where those clockwork CO2 spikes come from? After all, they accompany every interglacial.
See: Physorg.com -Even soil feels the heat: Soils release more carbon dioxide as globe warms for a helpful hint – 99.5% comes from natural sources.
In the above referenced web-article, these scientists have bumped their estimated current microbial contribution to atmospheric CO2 from 85 to 98 petagrams. Our anthropogenic contribution is less than a tenth of that at ~6-7 petagrams. The total of all natural emissions is estimated at some 2,000 – 2,200 petagrams. Now in this article they seem to suggest that our 6-7 petagram (sub 0.5%) contribution has unfortunately and deleteriously triggered this microbial increase of 13 petagrams (from 85 to 98). In fact, most all studies regarding Soil Respiration engage the very same broken blame-game.
However, if we humans were never here at all, the consequently expanded microbial contribution can be roughly estimated to become 127 petagrams. Microbes would have geometrically filled our void for an increase of ~42 petagrams. And expanded proliferations of insects and mammalia would have contributed to a yet much larger delta. So what would these Theologians suggest this far greater contribution would have “unfortunately and deleteriously triggered?”
