I can see how the biological "fast carbon cycle" can continue, but my concern is that the geological "deep carbon cycle" ceases, and that unopposed carbonate formation siphons away carbon from the biological cycle. I think this could end all life as we know it, although Li et al argue that it's not clear whether carbon or water will give out first.
