You missed underground aquifer depletion, which will only exacerbate climate change related drought. If you want to read about glacier delpetion you can do so here.
I said, "resource depletion - particularly fossil fuels." Water's a resource.
In principle, if energy were no obstacle, we'd have plenty of fresh water by means of desalination, and other resources wouldn't be a problem, either. Given their historically massive energy return on energy invested compared to every other energy source, fossil fuels are the limiting factor in our civilisation's current lifestyle. It's quite possible something else will run short first - for example, if Musk gets his wish of 500,000 electric vehicles a year, just his company by itself will use the world's entire current production of lithium - but fossil fuels are a definite limit on everything else.
And of course, there may be some other limit in things we can't predict. I read an interesting article about the extinct Tasmanian Tiger (a marsupial carnivore) pointing out Tasmanian Devils have this horrible contagious cancer wiping them out, and that in the past the Tiger used to keep the Devil population low and in isolated groups, which prevented diseases spreading across the whole population. The Devil could not really anticipate its need for the Tiger, but there it is. Nature is full of little cycles where you remove one little element and the whole system collapses. For all we know the destruction of coral reefs will lead to a collapse in tuna stocks or algae blooms, for example, by breaking the link in some predation chain.
That's all unknowable at this stage. There are definitely things to be concerned about and watch, of course. But what we do know is that fossil fuels are the big cog in the machinery of Western society, once you remove that cog the machine won't work the same way. And there is not much we can do in our own lives to reduce our impact on aquifers or lithium stocks or whatever, but there's a lot we can do to reduce our overall use of fossil fuels. See the action list above. First, deal with the problems you can deal with.
Even if climate change were not real and burning coal gave us vitamin C, we'd have to transition away from fossil fuels, simply because they're finite; in principle most other resources can be reused indefinitely (and many like lead from lead acid batteries already are reused quite a lot), but
fossil fuels once burned are gone forever. This means a lower energy consumption, more localised lifestyle, churning through less
stuff. This is not necessarily a bad thing, what's bad is changing because we have to rather than we choose to, and the political and social chaos which inevitably results from involuntary change.
Of course, depletion leads to people getting desperate. It's no coincidence that the Carter Doctrine came about a few years after the peak of conventional oil production in the US, and not before. And as production becomes constrained, disruptions to its flow become a very effective means of waging war, both on the direct target and the countries the target supplies with oil. Thus the attack on Saudi Arabia today, written about
here. We can expect more and more state and non-state actors doing things like this. And the essential problem is that oil prices under USD75 a barrel destroy oil companies, and prices over USD75/bbl destroy economies. This is why US shale oil has been heavily subsidised with loans despite almost never turning a profit, and why the GFC was preceded by high oil prices.
Ironically, events like the attack on Saudi Aramco's facility, the largest crude oil stabilisation facility in the world, will only make us dependent on oil for longer, since governments and corporations will put any reduction in supply down to events like this, and say, "well, it's only temporary so we don't have to change anything." Don't look for effective action from governments, though corporations will be
slightly more responsible since they are better able to look 10+ years ahead. Not all, of course, thus the GFC. But some.
Nonetheless, the most effective action has to come from us. Collapse now and avoid the rush. Start living a lifestyle with less fossil fuels, so that once it becomes compulsory you're used to it, and can pass on useful skills to friends, family and your community.
