Yeah, this is probably best practice for people in regions that are projected to be left mostly uninhabitable / with severe barriers to life. This won't really be too much of a problem even if climate change is left unchecked, as Bjørn Lomborg says[1], it will only cost us 2-4% of GDP by end of century.
> Civilizational collapse is a slow process. I doubt the people of the later stages of the Roman empire felt their society collapsed.
I'd like to point out an important note: the guy said civilization would collapse, not a civilization. I'm not sure if you mean the same thing he does, but civilization itself has never, in history, collapsed, even during the plague and fall of the roman empire. We've been pretty much A-okay on a global level since 12,000 years ago.
You're definitely right about individual states, and it is almost certainly true that several countries may end up collapsing due to climate disruption, but not the big ones and probably no time soon.
I'd go as far as arguing that _everyone_ should prepare for what's coming. All of us will be affected, be it directly or indirectly, through things like the (most likely) inevitable refugee crisis, or increased food prices and lower standards of living.
> but civilization itself has never, in history, collapsed
I meant individual civilizations and not civilization itself, although I read the original comment as something happening to "our" civilization and not all of them. Total collapse of civilization itself would require something cataclysmic happening on a global scale, and that the effects of said event are so severe that all of humanity fail to restore itself within the time span of several generations.
Some of the more alarmist reports about global warming are indeed pointing at that scenario, although it's more likely that progress will be slower, and that humanity as a whole will be able to adapt in the long run.
Regardless, I am convinced that even if we were talking about the actual end of civilization itself, it would not necessarily be evident to us until it was too late.
The fact that there are alarm bells ringing about the climate now is an indicator of climate changes being either:
a) survivable for humanity as a whole by doing what we can to prevent it and prepare for what happens if we fail
b) the end of the world and it's too late to do anything
This turned darker than I planned. :D
Actually, I'm pretty sure places like Greenland, Canada, Russia etc. will be mostly positively affected. I'm mostly concerned about the changes to the ocean when it comes to affecting all humans. The unfortunate reality is that unchecked global warming will probably lower food prices and increase standards of living in many places that are already rich, while causing destruction in places that are already relatively poor.
> alarm bells ringing about the climate...
The third option you left out is that the alarm is overinflated. With an issue as controversial as climate change, you can be almost certain that both the alarmists and skeptics are both wrong, and the truth is probably somewhere in the middle.
Also, I really don't think the end of the world is a realistic result of climate change. If you really want something to worry about, there are always meteors, gamma rays and the potential for nuclear war, superbugs, or biological WOMD.
Sane governmental response is a fantastic assumption. The orange baboon, along with present counterparts in Russia, Brazil, India, China, Turkey, Indonesia, Hungary are just a hint at what is to come.
First, why do you assume they would migrate north and not further south?
In your model do you expect people to move in or out of Australia, South Africa, Chile, etc. ?
I agree. I intended that to be implied as a possibility for the first option. Bad things will most likely happen, but it's unlikely that it's THAT bad.
The projections suggest that it's much cheaper to avert climate change than to deal with the consequences, and much less painful.
If we can afford to lose x% of GDP dealing with the problems, why can't we spend less than that to avoid the problem, and avoid a huge amount of human misery and ecological collapse in the process?
We can, and we are. That's why I do what I do.
You're absolutely right, it is much cheaper to avert climate change than deal with the consequences. It's also necessary to transition to sustainable energy eventually because we will run out of fossil fuels regardless of what happens with the climate.
The solutions to climate change are being worked on right now by many talented people around the world. I'm confident we will reach the IPCC SR15 1.5 degree Celsius goals.
Action is falling far short of what would be needed to cap temperature rise, and there is no motion toward greater enforcement.
Any developments in fission could only have substantial effect decades after events will overtake them.
We only need 2 decades to fix the energy part of emissions, and the IPCC has given us 3.
> and there is no motion toward greater enforcement.
Enforcement isn't needed to get to net zero emissions. It's profitable long term to swap to clean energy and electrified vehicles and appliances, they're more efficient. Also fossil fuel abundance will eventually drop to the point where prices rise.
Free markets will solve our emissions problem, I'm not sure why you are worried about enforcement or the type of governments when it comes to this.
Egyptians lasted for 5000 years before christ was born, their civilization had expired completely during the rise of rome.
our modern society requires (depends) on specialization. It is not good at adaptation.
Our brains principally stopped evolving 50000 years ago. We're still learning how to use them and enhance/repair our bodies.
Gdp is 100 years old. We're not using gdp for anything in a ClimateChange multiple species foodchain collapse. Capitalism is 150 years old.
We probably aren't even using money in 100 years. A quantum supremacy machine has broken bitcoin satoshi blocks. Elons neurAlink connected by starlink allows us to communicate telepathically. If his hypermind doesn't build it by that time then mine will. Cheers.
Ahem.. Humans have only had rationale thought for the last 50000 years. We are classified as Greater apes.
Destabilized governments run by extremists and nuclear weapons. Trumps usa deny Climate change. Fuch koch.
It was a good run. Unchecked climate change toxins from unchecked reactors exploding, blabla caused by heAT triggering rising water tables.. Godzilla.
Its a Multi species collapse. Nothing humans have ever experienced. Nothing mammals have ever experienced. Stfu and join r/extinctionrebellion
No doubt about it. At this point it's probably a better idea to start preparing for the changes rather than stopping them, unless we somehow manage to achieve some magical global unity around a single goal.
> I don't see why civilization would collapse any time soon
Civilizational collapse is a slow process. I doubt the people of the later stages of the Roman empire felt their society collapsed. It's more likely they simply experienced slowly decaying infrastructure as maintenance was neglected, social unrest, and the absence of the advantages we get from a large centralized authorities, all in a span of many decades.
I'm not saying that it's happening, or not happening -- It's just that you wouldn't know until it's happened.
