After the last ice age ended about 11,000 years ago, the amount of atmospheric CO2 dropped for about 4 millennia, reaching a low of about 260 parts per million (ppm)--or 0.026% by volume--around 7000 years ago.It warms up, but atmospheric CO2 dropped. What kind of greenhouse gas is that? Doesn't that contradict their model with a positive feedback from atmospheric CO2?

Preindustrial People Had Little Effect on Atmospheric Carbon Levels Just like us.

The Group is going to have to be informed about you.

...a combination of vegetation buildup after the ice age and, more prominently, the slow reaction to this change by ocean chemistry. Geez. How did I know this even before I got to this part of the article.

"It warms up [ between 11,000 and 6,000 yrs ago]
, but atmospheric CO2 dropped [substantially]. What kind of greenhouse gas is that? Doesn't that contradict their model with a positive feedback from atmospheric CO2? BINGO - The killer question that nukes the premise!!!!

What’s interesting, really interesting, is that “vegetation build up” helped cause temperatures to rise.
Doesn’t that imply that planting trees will cause global warming?
