Carbon removal will eventually be necessary to reach carbon neutrality. We're very very far from the point where it's more economical to invest in carbon removal than to lower emissions.
I thought starting him at an 8% interest wouldn't give him the motivation. After a few months we had a talk and he saw the power of compound interest based on these crazy numbers, and we've adjusted it downwards since then. Of course he was a bit disappointed but understood this was closer to the real world.

CO₂ will react with certain minerals (like Olivine) over time. Also, when CO₂ is dissolved in the ocean, it will form an acid that reacts with lime. So there will be an equilibrium again, but it will take quite some time.

However, especially Olivine is also thought to be useful for the same reason as above, to be used in climate control efforts: Just mine it, crush it and spread it over a large area to cheaply capture more CO₂ more quickly, and bring that equilibrium lower and sooner: https://climatecleanup.org/olivine/
> why would it be a bad idea to reduce the level of pollution in the environment

For the record I do believe in climate change, and think we need to deal with it. But to answer your question, if climate change indeed _weren’t_ caused by human CO2 emissions, then why would atmospheric CO2 even count as pollution?

Combating climate change isn’t some simple and easy change. It would require people to dramatically change their way of life, usually for the worse (smaller dwellings, less AC, fewer children, less meat consumption, no non-essential international travel, etc.)

It wouldn’t be worth doing if atmospheric CO2 were benign.
Your point about the horrors of sexism is well-meant, well-taken, and morally correct in every single possible way.

Do you think it might be useful information to consider that years of China's one-child policy and strong cultural preferences might have combined to create a serious skew in the gender ratio? India has a related issue. https://www.washingtonpost.com/graphics/2018/world/too-many-...

Again, you're absolutely correct that this sounds like an utterly repellent expression of privilege and sexism. It's just worth perhaps considering that demographic context might be considered by some to be relevant.
Ask HN: What is the go-to reference for human technology?
(Posting as a separate Ask HN since it was suggested https://news.ycombinator.com/item?id=27770117 )

Just because a technology becomes obsolete (which IMO has a negative connotation) it shouldn't mean it should be forgotten and the principles used in ingenious designs can't be reused elsewhere. Best I can find is museums or history of technology books, but no catalog. Surely there must be some good reference out there?

My first thought was wikipedia, but that is too disorganized in this sense because it encompasses much more than technology. I'm thinking of some sort of outline where one could find collections like [0] in the 'mechanisms' subsection, and possibly comprising of multiple other subsections such as 'electronics', 'agriculture', 'materials', and so on. Perhaps this is too broad and why we have mixed sources like patents/encyclopedias/etc?

There are some sources of carbon emissions that are very hard to replace. Eventually it will be cheaper to remove some carbon than to get rid of the last emitters.

Why does that come to mind? The explanation provided does not explain everything even within the confines of climate science. When massive amounts of energy are added to a dynamical system there will be chaos before a new equilibrium is obtained. This is not controversial. It’s settled science. The heat dome in question is not just a bunch of new local high temps. That’s the wrong thing to look at. It’s a large high pressure mass doing things that the equilibrium established before the industrial revolution largely prevented.
Not making a sacrifice viewed as unnecessary, presumably? No mitigating action is free.

Even on the opposite side you have to decide where to draw your line, how much to spend on tackling it; how much is enough, how much is a waste that could be spent on something else.
Anything going into the lungs besides atmospheric air, and specific medications, is potentially inflammatory. At best, the VOCs (in vaping) do absolutely nothing in either direction. At semi-worst, they cause low-grade inflammation, and worst-case they cause chemical pneumonitis.

However, by comparison, tobacco smoke is like "what if we could engineer the perfect lung assailant."

Tar causes inflammation, damages DNA directly, intercalates DNA and induces replication errors, collapses alveoli, and paralyzes cillia, making clearance of all those chemical assailants from the lungs even harder.
There does seem to be a reluctance by assistant referees to flag very obvious offsides, such as Italy's against Spain, meaning players run off celebrating, while VAR is reviewed and the goal is inevitably disallowed.

> The technology could propel China to dominate global pharmaceuticals, and also potentially lead to genetically enhanced soldiers, or engineered pathogens to target the U.S. population or food supply, the advisors said.

Or genetically modified viruses that target specific populations. Forget the food supply.

Something like a Covid-19 with a bit more specificity and a little more lethality.

No wonder the military has their hands in this.

And in this context, this is interesting:

Marlboro know they're above consequences for their product safety, and they've done this kind of thing before, so they're going to do it no matter how unethical it is.
> A carbon emissions tax could be politically viable if it was coupled with an income tax reduction so as to be revenue neutral. That way most people wouldn't be worse off.

Even better: Couple the carbon tax to a flat tax credit which is revenue-neutral to the government. Such a tax would be naturally progressive. It also avoids a perverse incentive to keep polluting to maintain the tax base.
>"That's all. That's the difficulty. That's why quantum mechanics can't seem to be imitable by a local classical computer."

I don't think argument is about efficiency. "a classical computer can perfectly simulate a quantum system/computer" is not explicitily there, it's an argument against that. It seems to me you're saying anything that's not strictly proving BQP > BPP supports something else.
> A high-priority item for the environment is simply education, since voters are pushing strongly against clean energy ("wind turbines kill birds", "nuclear plants go Chernobyl", "electric cars are expensive|auto-update like Windows and brick on you|have no turbo", "batteries are worse for the environment than fossil fuels").

Lack of media representation seems like a widely under-attacked problem. Look at the number adults who say they hear about climate change in the media at least once a week, the numbers are abysmal: https://climatecommunication.yale.edu/visualizations-data/yc...

Yep -- this is how I use my vape, to reduce my overall MAOI intake. And I started smoking to begin with for the antidepressant effects (which it's surprisingly effective at).

Were I to switch to vaping alone, it would be far easier to quit, mainly because the nature of conditioning relating to a vaping habit (hitting my juul at my desk) is very distinct from cigarettes (going on the roof and having a smoke triggered by certain events). The latter is far more "attached" to specific event triggers and lasts a specific amount of time, while the former is a more "ambient" act with much less habituality attached.

> If humans hadn't influenced the climate to the extent that they have, the event would have been 150 times less likely

A change in odds by a multiple of 150 does not equal "virtually impossible". Imagine 1/1000 vs 1/150,000 odds for a multimillion jackpot. Our weather and climate system is unfathomably complex. The odds that a compter model is correct is "virtually impossible".

Meanwhile the EU exempted private jets (including the use for "leisure") from fuel tax, to be "phased in" later.

Yeah, OK, if they can fly private jets for leisure, why should I bother recycling a mountain of materials to offset that?

> Also I think you need to be clear on absolute vs relative decline - the population of the UK hasn't declined in absolute numbers, nor has its economy, and whether you mean "size of economy" or "GDP per person".

He's talking relative. And it matters. For example stuff stops being sold/is never sold in relatively small markets. We're starting to see it with China-only products. There are many disadvantages to being a smaller economy, even if in per capita terms things are ok.

And almost all European countries, taken individually, are predicted to fall outside the top 10 by 2050 (moderate chance for 2050 and huge chance for 2100).
Why? Both are just equating correlation with causation. Of course we know drunk driving increases deaths, but if that wasn’t obvious then you couldn’t say either of these statemens.

My twin did it. So much for privacy.
The book "The Wizard and the Prophet" (highly recommended, by Charles Mann) argues that this is essentially a battle between faith in technology to become more efficient and the nature-preserving belief that we need to reduce our footprint.

The battle has been going on for centuries regarding the limits of population capacity, energy, water and food. We have broken many previously credible thresholds and managed to get to 11 billion people thanks to technology.

I don't think following only one or only the other strategy is something that's possible in diverse societies. We will continue to wage this battle, with technological advances bringing breakthroughs (such as the invention of fertilizers or climate-robust seeds), but with ever starker warnings from conservators.

The book helped me realize how many debates are rooted in this schism, deep down, and how fundamental it is.

When it comes to the fossil fuel companies, my objection to their carbon capture is manifold.

Clean coal has always been a sham, so I don't have faith in their schemes for scrubbing carbon. These companies have shown no real appetite for actually fixing the problems they created, and a near infinite appetite for juking the stats.

As an example, they always block any semi-reasonable economic systems for carbon taxation and pricing externalities which would be extremely effective at fixing the problem from a consumer demand perspective and pricing in mitigations for petroleum use.

Their sequestration seems largely about pumping CO2 into the ground. I'm not a geologist, and I can't speak to how effective that is at keeping gas from leaking back to the surface, but stories about fracking ruining the water in large areas due to _gasses_ coming up from the ground don't give me faith. Maybe the strategy is to shove enough CO2 around mineral strata like olivine that eventually absorb it but the entire process sounds like it is rife for abuse: oil company SAYS it shoved it down there, SAYS it will stay there, just to get whatever capture credit. Do they actually care if their carbon gets in the air? Historically the answer is absolutely not.

And the article is right, bad science reporting in the press will misrepresent the problems and solutions, like they have for, oh, since the press has ever existed for science in general and 70 years specifically for oil/gas/global warming/the environment.

Nations DON'T have to be poorer. Alternative energy is cheaper than coal, and last I checked was on even par with natural gas turbine, and soon new alternative energy will be cheaper than already-installed gas plants, an important milestone that means the electric companies will actively try to shutter since replacing them saves them money.

The BEV will drop under ICE drivetrain cost very very soon. It probably has already, but the design cycle of cars using those technologies is probably on a 2-5 year delay from showing up in the marketplace.

So the third world's transportation and energy infrastructure will be largely decarbonized. I think that's about 50-60% of emissions in the emissions pile.

Your argument seems to boil down to "make solving the problem by means other than carbon capture seem impossible or repressive". I disagree.
Opnsense has been far more consistent with their upgrade releases.

Migration is really a complete reinstall and rebuild of your rules. I took a backup of my physical pfsense box and restored it to a VM then reinstalled opnsense on the physical hardware. With the pf box running in a vm I could just reference it while creating new rules.

I think someone made a script to load a pfsense backup onto an opnsense instance but I really think you’re better off with a clean slate.
I feel like I've gone through the five stages of grief with climate change, and I'm finally at acceptance.

There are too many forces pushing it further than to prevent it, and governments won't come together to actually do something about it until it's too late.

Everything that has a beginning has an end, and maybe this is ours. Over time the earth will heal without us, so instead of worrying about something out of our control (as individuals), how about we just live our short meaningless lives as comfortably as we can and do whatever we want until we die.

You also need to account for grid scale energy storage to deploy renewables at any meaningful capacity. Unfortunately we still don’t have a cost-effective solution that works at grid scale. Batteries don’t last long enough.

Yes. 100%. For us living in the suburbs, planting additional trees, native wildflowers, and other plants can have a cooling effect (trees) and hemp animals as well.

We should also seek to oppose new car-centric development that increasingly destroys what remaining natural habitats we have. Watching Canadian Geese (as mean as they are) get run over by cars in the parking lots of furniture stores selling cheap crap shipped over from other countries is so stupid and unnecessary. And we can prevent it too.
No, they don't. A few do, but the operation is expensive, painful, and not always satisfactory. Many will take hormones and some will have non-genital surgeries, but full gender confirmation surgery is for a minority.

A great many, perhaps a majority, don't do anything to their bodies at all. They change their clothes, their pronouns, their hair, and their lifestyles, but have no surgery or medicines. They live in society as their gender, and anything that's seen only by the people they're intimate with are a subject for discussion between them.

The result is that yes, there are a fair number of men with vaginas and women with penises. Which doesn't matter to you unless you're either their doctor or their lover, but it's important to recognize that it is in fact the case.
Didn't China pledge to go fully carbon-neutral by 2050 or something?
p = newPerson();
w = walk(p);
t = talk(p, w);
s = shout(p, t);

becomes,

seq(shout, seq(talk, seq(walk, seq(newPerson())))

"infix",

newPerson() seq
walk seq
talk seq
shout

The operations `newPerson` and `seq` form a monad.

If you can omit `w =`, `t=`, and `s=` you have an applicative, rather than a monad. Ie., the operations being sequenced are independent.
Your citations don't back up your claim that "the main reason smoking causes cancer" is polonium 210. They just note that polonium 210 is one possible reason for smoking causing cancer. From your [1]:

> Do these doses lead to lung cancer? It’s hard to say, especially since the effects of polonium are only part of a wider range of damaging consequences caused by inhaling cigarette smoke. But animal studies certainly give us cause for concern.

Moreover wikipedia cites two articles saying:

> In contrast, a 1999 review of tobacco smoke carcinogens published in the Journal of the National Cancer Institute states that "levels of polonium-210 in tobacco smoke are not believed to be great enough to significantly impact lung cancer in smokers."[224] In 2011 Hecht has also stated that the "levels of 210Po in cigarette smoke are probably too low to be involved in lung cancer induction".[225]

>I've also been religiously recycling in my personal life but every now and then I read articles about even recycling from a lot of places ending up in landfills which really frustrates me as it takes away any agency I really have on this action.

Recycle if you want, but don't stress about it (especially religiously).

One, for the landfill reason you mentioned, and two, while it does feel good to 'do something about it', the scale of individuals recycling doesn't make up for massive companies generating waste without recycling. If you want the agency back, you'll likely have to get into politics, activism, and/or join those companies and change them from the inside (note: incredibly difficult side quest)
