comment Would oxygen levels be stable without photosynthesis?
Also, maybe worth clarifying what "the entire organic carbon reservoir" is referring to. I'm assuming it means all life on earth, plus all fossil fuels we could conceivably dig up.

comment Would oxygen levels be stable without photosynthesis?
So basically Unger's claim is based around the ideas in third reference (The last link is worth a read): carbon is the limiting reagent in the C + O2 -> CO2 reaction? My gut reaction is that in the absence of photosynthesis we don't live in a bistable system: we'd eventually return to the state from billions of years ago. But I can believe that initially there would be very little change.

I looked up photochromatic step, but I'm not sure what I'm looking for, do you have some link to whatever you're talking about?

comment Can a human smell through the ears?
do you mean "are there olfactory receptors in the ears" or "can smelly things make their way through our ears to the nose". Cause in the second case, the eardrum is in the way.
