An ice age is a global temperature difference of about 5 degrees. So we are going to have at least a third of an ice age’s temperature delta in heating, if we do everything right, and two thirds if we do business as usual.

Let's instead get rid of private air travel. Has caused a pandemic and millions of deaths. And the emissions are very likely larger than those of Bitcoin. People can go on vacation by train instead. If you demand people use slow legacy money then I can demand slow legacy travel, ok? ;)

I see you're getting downvoted but maybe "get rid of" isn't the best approach. Certainly taxing air travel at a chunky rate would reduce unnecessary flights.

Taxing it means : the rich will be able to continue to fly while the poor, not being able to travel anymore because of the tax, will support the burden of climate adaptation. That's not justice.

And that's the issue : climate change requires a global effort and if we want to have the masses to adapt, then we must have the elite to adapt equally.

Are these simulations public? Can I run see and run the code? Are all aspects taken into account that can affect the outcome, such as, Earth's magnetic field strength, activity of the Sun, shifting of magnetic poles?

If you have a spare supercomputer I'm sure the scientists would be happy to help you run their stuff. The IPCC report cites its sources, you can go and check who the authors are and what the models take into account.

Yes and I don't think people are going to wake up till everyone faces the consequences of climate change in their personal lives, which is quite honestly just sad.

It seems fairly obvious that climate change is going to be solved before the bigger existential risks we face, which are for the most part unknowable or largely ignored. There are a lot of people working on climate change now, it's well established in the public's mind, and there are many incentives in place to accelerate solutions.

It also seems companies are moving faster than politics. E.g. deprecating ICEs by 2030/35, without any policies forcing them. The mere discussion about increasing CO2 prices triggered coal power plant operators to think about phasing those put before any policy enforced coal exit.

The pessimist in me will only believe any of that, and any positive impact, once it happened. Not sooner.

Here's an informed article on bitcoin's energy use [0]. [0]: https://hbr.org/2021/05/how-much-energy-does-bitcoin-actuall...

"The vast majority of Bitcoin’s energy consumption happens during the mining process. Once coins have been issued, the energy required to validate transactions is minimal." Honestly, that doesn't seem particularly well-informed. I wonder how this person thinks transactions are committed to the blockchain, and how this is separate from the mining process? Unless they literally mean "the energy required to consult the…

The quote you referenced makes the distinction between committing (mining) transactions and validating. The energy used to validate transactions is indeed minimal.

The energy used for validation is a useful metric because it's how the bitcoin network can afford to stay decentralized.

Just tax carbon instead of trying to pick winners and losers

On what evidence is your opinion based?

That a carbon price is a good idea is pretty well known among economists. I believe there was a Nobel price for the idea.

These people are not the ones who need to take action, so who cares?

Policy makers are the ones who need to act, and they are already well aware for most of the consequences of global warming. The issue is that a lot of big corporations (The ones which really control police makers) are not going to be advantaged by transforming the society to a more respectful one regarding nature. So things move slowly, until things are getting really bad and day to day activities are drastically affected by global warming

Also people need to be presented with the consequences. I still know a lot of people who genuinely believe it means slightly warmer summers. They think I'm a crazy person when I mention the never-ending storms and lack of drinking water. Also just dropping this link here as I remember watching it at the time and thinking isn't it great we're not there yet: https://www.youtube.com/watch?v=6CXRaTnKDXA

Yeah, I don’t mean to be disparaging but the average person doesn’t really seem to grasp this beyond: it’ll be slightly warmer. And in a cold European climate, most people seem to think that’s a good thing. Warm summers are enjoyable when you’re swimming in the sea and having barbecues in the park.

Maybe there should be more focus on the frequency and intensity of storms, floods, extreme heatwaves, etc.

Although to be honest if this is lost on people up until now anyway, what hope is there?

A significant number of people just don’t seem to care.
