Thanks, I’d never really considered the impacts climate change would have on oxygen. I looked into this a bit and it seems to also be the case that rising ocean temperatures also reduce the capacity of the water to hold dissolved oxygen, which causes a nasty feedback loop.

So while there’s not an immediate risk of atmospheric oxygen concentration dropping by any significant amount, there is a real concern of oxygen concentrations in the oceans dropping pretty drastically. This then accelerates climate change even further and could have longer term effects on atmospheric levels as well.

Sure but anthropogenic climate change is an issue of greenhouse gas accumulation rather than a lack of oxygen, no? Rather than there being too many people literally just using too much oxygen.

Are we concerned about the amount of oxygen available now?

Assuming that the education could be free, why wouldn’t you expect people to train as surgeons?
