Abstract
Levels of atmospheric carbon dioxide constrain vegetation types and thus also non-biological uptake during rock weathering. That's the reasoning used to explain why CO2 levels did not fall below a certain point in the Miocene.
The world is currently at risk of overheating in response to all the carbon dioxide being pumped into the atmosphere from the use of fossil fuels: the current atmospheric concentration of CO2 is about 385 parts per million (p.p.
