> In order to prevent global warming, we'd have to stop putting carbon into the atmosphere entirely.
There are processes that remove CO_2 from the atmosphere. Take photosynthesis as an example. Animals have exhaled CO_2 as long as they existed. We do not need to stop it.
(There may be a point that restricting the output to sensible levels is worthwhile. But the sensible level can be above zero.)
Yes, there are processes that remove CO_2 from the atmosphere. And these only have enough power to compensate for natural outputs of CO_2, like that produced from respiration.
When we burn fossilized fuels, we're taking fossilized carbon and putting it into the atmosphere- billions of years worth of the natural process of fossilization reversed nearly instantaneously. In order for that to be compensated for naturally, we'd have to increase fossilization rates. This is impossible. Only a comparative technological solution to increasing fossilization rate (i.e. figuring out how to bury all that atmospheric carbon) will work.
