Get in a time machine. Go back to 1970. Make sure world starts phasing out all coal power by 2000, replacing with nuclear and what renewables are available then, and make sure modular scalable reactors are available for China so they use that instead of coal to power their rise. Convince everyone that late 20th century unscientific greens are full of shit and nuclear power is better than coal.
(Renewables were not fully competitive with fission until the 20teens, too late.)
It’s dialed in.
That’s not to mean replacing stuff with non carbon emitting sources today is worthless. It’s very important. Right now we are dialing in the next escalation of the problem, and we can still blunt that if we give a damn.
One thing you can do today is keep arguing against the romantic anti industrial unscientific greens. Degrowth and “abstinence based” policy will never work. People will never go for it, and we are never returning to pre industrial times. It’s a fantasy. If you try to force it people will elect anti environmental populists (as they have) and you will get the opposite of what we need.
Fantasies displace realistic solutions in the discourse, and “everyone needs to become poorer” gives anti environmental and fossil fuel industry shills a way to frame their case as “we are on the side of human development.” Don’t give them that argument. Stop it. It also won’t work with developing nations. “Hey Africa, we know we colonized you and all but can you do us a favor and stay poor to help fix the problem we mostly caused?” There is not enough “fuck you” in the universe for that one.
The solution is to replace fossil fuels with non carbon emitting sources, not to stop people from using energy.
This is a gross misunderstanding of what degrowth means.
The fantasy is that an economic system predicated on infinite growth can be made compatible with finite resources. Take, for example, the fact that renewable energy keeps growing as a percentage of total energy generation, yet total GHG emissions keep rising. That's a result of the system of incentives set up by capital. Yes, the economy can become less coupled to resources (as it has), but there is a limit, unless you seriously want to argue that iron (for example) can be an arbitrarily small portion of the economy.
An economy is a method of allocating resources. This economic system is extremely terrible at meeting base human needs (consider that we produce many times the amount of food that's needed to feed everyone's needs, but massive amounts of it used for industrial meat production and biofuels).
> we are never returning to pre industrial times
This is an absurd strawman.
> everyone needs to become poorer
This is, in fact, the industry propaganda. What degrowth advocates for is taking as our first priority meeting human needs and living sustainably (which can be made compatible with most of the technology we have today in some form), rather than the ideology of growth for growth's sake, which mainly results in massive amounts of wasted resources and funnelling wealth into the hands of a few.
> “Hey Africa, we know we colonized you and all but can you do us a favor and stay poor to help fix the problem we mostly caused?” There is not enough “fuck you” in the universe for that one.
This is misdirection. Getting water, food, shelter, and medicine for everyone on the planet is well within our means as a species. It is the ideology of free movement for goods but not people and infinite growth that makes it impossible to meet those needs, because it requires and underclass who can be used for cheap labour and contained in states built for that purpose.
It's not poor people who stand to lose from degrowth, it's the ultra rich.
"we are never returning to pre industrial times"
We are, one way or the other. It is just a question of the choices we make on the way and how pre-industrial we end up.
There is no a position of leverage, the climate is behaving as modeled and expected. We know what will happen next.
In Europe, we're already degrowing since 2008, even more so if you only look at the real, physical economy because we have to import our fossil energy. We won't be able to power the same lifestyle with nuclear and renewables either, the math doesn't add up. Jean-Marc Jancovici is a french engineer explaining this in great detail, see for example https://www.thegreatsimplification.com/episode/84-jean-marc-... if you don't speak french.
