I think it's irresponsible to act as though the climate crisis is just a matter of weather, and not how also we will respond to it. Resource shortages caused by the climate crisis could cause resource wars, and if weapons of mass destruction are deployed during those wars, that could easily finish off homo sapiens. The mere collapse of civilization and mass death should be bad enough that we take drastic action to pr…
What shortages? The world overproduces food by no small margin. Starvation is a regional supply issue. In developed countries 30-40% of food often goes to waste. Alternative water supplies like desalination exist, and countries like Israel with constrained natural water supplies use it extensively. I think it's irresponsible to proclaim that humanity is doomed without a coherent argument as to why it won't be able to…
Desalination is prohibitively energy-intensive. More so in a world of shrinking resources.
You're arguing for precisely why these shortages are a problem but you think you're arguing against their existence. A "shortage" is not simply a hard supply number -- it's also defined by how well the supply is utilized. And the problem is precisely that humans are, and will presumably continue to be, selfish and horrible at using even sufficient or even surplus supplies. So why in the world would anyone think that we'll adequately deal with actually shortages?
