I worked in climate policy for awhile. I got out of it because I lost hope. I believe our governments have lost hope also. Covid taught us that if they inflict the necessary pain to control carbon, our governments will be consumed by populist anger. Only the Chinese system appears to have any hope of controlling people’s behavior that much without riots. And what a terrifying system! Even their control began to slip…

You are right that degrowth is not a politically viable path to saving the climate. Additionally, it is not effective unless you want to return to pre-industrial society. What works is: Changing the source of the energy we consume. Solar is the cheapest source of energy now. Wind is good in some areas. Nuclear can be useful too. The amazing thing is that solar is so cheap now, there is basically no way stopping it. W…

I wouldn’t call it just useful. As far as I understand it’s the best realistic shot we’ve got.

Isn't the number one reason that nuclear gets a bad rep because there is no compelling solution for getting rid of the waste?

There are compelling solutions, they just run into the same opposition as the plants themselves. https://en.wikipedia.org/wiki/Yucca_Mountain_nuclear_waste_r...

There's also the Finnish solution.

Mere ~30 years after discovering the Greenhouse Effect we managed to split the atom, harnessing heretofore unimaginable amounts of energy. Yet almost 100 years later, here we are - Oil and gas dependent, boasting an energy and climate crisis, all the while fooling regulators with worthless climate certificates, unaccountable off-shore factories and just plain rampant fraud when it comes to CO2 emissions.

> worthless climate certificates I think that carbon offsetting is a good idea in the spirit of a glass half-full. It's unrealistic to expect the world economy to quit fossil fuels cold turkey, and a system that allows those who cannot transition to externalize their ability to reduce or eliminate emissions is a way to get close to the desired result with the constraints we have right now.

I also think it's a good idea, but there are too many loopholes[1] for bad actors to abuse at the moment.

Our governments are so dysfunctional and corrupt our only hope is that AI will actually be benevolent and can help guide us and solve problems. Because, as the comic, and thousands of other examples show, our governments aren't actually capable of leading and solving problems, even when the problems are blatant. Same when the solution is easy, but it will cause the wealthy to lose money, see US health care and taxati…

We should stop acting like AGI is just a matter of time and that it'll save all our problems, this is borderline a cult at this point.

1975: The first cancellation of a planned nuclear power plant occurred in Wyhl, Germany due to protests from "environmentalists".

That's good news, take it further!

Perfect is the enemy of good.

As a result we're now relying on more coal and gas than the much cleaner nuclear energy. What lovely progress!

> As a general clarification, ounce for ounce, coal ash released from a power plant delivers more radiation than nuclear waste shielded via water or dry cask storage.

What a comparison... The worry with nuclear waste is of course that the shielding doesn't last long enough and waste then contaminates surroundings with much much higher radiation than in coal ash

Why not solar, wind and storage?

To decarbonise transport storage needs to massively increase. There are 30 million cars in the UK, that alone is 3TWh of storage, which isn't far off a day's total energy use. If we can make 3TWh then it's reasonable that we can make 2 or 3 times that much.

It won't be financially viable to operate a nuclear plant for the few days a year that the wind and solar and storage and imports can't cover the use, better to simply increase storage and production a bit more.

And yet CO2 per capita is much lower in Germany than in the US. So Germany must also be doing something right.

Not for electricity production.

Europeeans tend to have less disposable income and be less consumerist, smaller and better heated/insulated houses, less cars per household, &c.
