Engineers (and systems scientists, who are really engineers) are the people who analyze feedback systems, so they're excellent people to ask. Burt's ppt is superb, and you could learn a lot from it, if you took the time.

@BrknMan @KCTaz @chimera414 @rattibha @CarlaSpade @nvangelder03 @IngersolRobert @Kenneth72712993 @Tokyo_Tom @O 2/4. Unfortunately, volcanoes de-sequester CO2 only very slowly, and there's evidence that they do so even slower during glaciations:

Here's a paper:

@BrknMan @KCTaz @chimera414 @rattibha @CarlaSpade @nvangelder03 @IngersolRobert @Kenneth72712993 @Tokyo_Tom @O 3/4. You're correct that natural negative feedbacks regulate CO2 levels, and they're the reason CO2 levels bottom out during glaciations, instead of falling below about 180 ppmv. But the main way that feedback works is by killing plants, as Burt described.

@BrknMan @KCTaz @chimera414 @rattibha @CarlaSpade @nvangelder03 @IngersolRobert @Kenneth72712993 @Tokyo_Tom @O 4/4. The CO2 feedback mechanisms are a lot more pleasant when they limit CO2 increases, than when they limit decreases. They limit decreases mainly by killing off C3 plants. They limit increases by greening the Earth:
