Not to forget, we are dependent on the food web. These changes mean species will be wiped out, fishing stocks will crash, and invasive will spread.
Since you are likely in the developed world, tropical temps in Europe would mean refurbishment of houses.
People won’t remember things like the lakes freezing over or ice skating.
Society won't collapse. Humans will do amazingly evil things to survive. The British were happy to starved millions of Indians to death until the country gained independence. All to support the British empire. We live in an era of basically unprecedented niceness in the history of humanity. Even the great empires of the past oppressed and killed multitudes more through slavery or serfdom or constant expansionist wars or other such means.
> refurbishment of houses
Perfect work for refugees to do at gun point.
Billions may die but society will go on with a somewhat lower regard for life and a larger amount of nationalism. Arguably what we consider western society will collapse but that's only existed for under a century.
In some ways that is more depressing than society simply collapsing. We will leave behind a rotting zombified corpse of our society to future generations.
It is easy to write provocative things when we do not let ourselves bear the weight of their implication. This is horror being outlined.
In earnest conversation, these are sombre and sobering implications, not frivolous or minor things.
This is a sea of humans, extending from one end of the horizon to the other, hungry, lost, frightened, confused, sad and angry. It is the loss of culture, history and fascinating things that one cherishes.
> In some ways that is more depressing than society simply collapsing.
The inability to discuss a horror in realistic terms is how you get a horror. Not exaggerated "society will collapse" but actually tangible realistic and terrible outcomes. Society collapsing is an abstract and nebulous thing. The thing we will get is much worse and unless we look it in the face we will get it.
You already said these are massive geographic issues.
Yet these different, large, geographic problems are of a size that doesn’t end up having even a remote effect on human civilization?
How? Is there some geography which is not impacted at all? A geography where a massive portion of human civilization is situated?
You're driving at changes to how we live.
Changes to how we live, even large ones, does not equate to "the end of humanity."
This is what worries me.
At some point more northern facing countries will decide enough is enough and start mass genocide of any population attempting to flee.
Europe will be ok with just killing a few hundred million trying to flee in boats, and the eastern frontier is securable, especially with drones, but even with conscripts. Hell Ukraine has done a solid job on its own against an organised army on its doorstep.
America will act as a buffer for Canada and will have no problem with wiping out refugees. Argentina will be interesting but it's too small and isolated to matter globally.
The big global risk is that India and Pakistan have nukes and will be trying to flee into China and central Asia.
Setting aside refugees, far bigger risk for Europe isn't reurbishment of housing, it's tropical diseases in the south, it's the collapse of food security, and the general collapse of society as the economy falls over.
I find it very difficult to maintain an even tone and address statements that posit climate change positive effects on society.
There are so many incredibly bad things about climate change it boggles the mind.
I try and believe people are burying their heads in the sand to avoid the pain of reckoning with the end of everything they hold dear. This ends up with punches being pulled.
