Even if you get it to zero, the resulting concentrations will still accelerate into the right. Even if you get it negative at the same rate we're producing it today (which would eliminate all human co2 contributions EVER in ~60 years) wou…

That's just it. It used to, but it doesn't. At this point global warming is self-reinforcing. So while it's correct what you say, the implied corollary is not true.

The implied corollary is of course that if we slow down emissions global warming will stop. And it won't. It will slow down, but not stop. Not even if we get net emissions to zero.

I've noticed you keep making posts that boil down to 'I do/am/believe ' without it offering much relevance or insight to the discussion. It seems like you're just live blogging on HN. I'm very curious what your reasons are for doing so. EDIT: I'm honestly curious. It doesn't bother me too much, and I'm sure I've made comments that I thought were valuable but in hindsight were probably just me wanting to be present. I…

It's a discussion thread. I add my input, maybe you find it relevant, maybe you dont. Maybe I don't add enough insight. Fair enough. But it's honestly fucking weird that you are tracking my comments.

I often click on the user's comment history if a comment stands out positively or negatively, and I realized that I'd done so more than once with yours. I don't think that counts as weird.

That said, I did write a bunch of code that actually allows me to track a user's comments. But I wrote that mostly so I can get updates if infrequent but great commenters post something. Perhaps that is a bit weird.

I'm curious why the small community emphasis?

half subjective reasons: - I'm bored by the system and jobless, and this would be an interesting thing to try as an activity for me - larger efforts are slow - I have this vision that bootstrapping small group efforts my heat up the system to help larger efforts. I may add that large changes are bouncing back and forth between 'people are responsible' and 'industries are responsible' without going much anywhere. And…

Ah so more for personal reasons fair enough. Digital efforts could scale in a nonlocal way with teaching theoretically but people would need to take interest although it could help if they say see an easy to make hummus as a healthy and delicious dinner to get them to natrually start eating less meat not as an end goal but because of legitimate preference.

Oh the digital part is mostly a few bits of calling and logging, I don't want any sophisticated tooling, the goal is gathering and enjoying learning/doing together. I don't know what to cook off humus, but surely by having great new dinners, hobbies that are fun, eco friendly is the goal. Basically low on resources, high on pleasantness.

I'm sorry to be that guy, but I really think blockchain offers solutions to these types of coordination problems. For example, Aragon just launched their mainnet today. They made a platform that allows distributed collaboration between groups of people. I think this could potentially reduce bureaucracy and reduce the time between idea and implementation. I have zero stake in Aragon btw, I just find it fascinating and…

Crypto could also become one of the biggest contributors to climate change, since it’s literally just wasting as much energy as possible to make money.

The monetary system itself is a big contributor or climate change. Kings used to require empires in order to protect their gold stores. I think securing the longest PoW (or PoS) chain is a very good use of resources, as it's tantamount to a king protecting his gold.

How does Aragon's effectiveness for this compare to e.g a Google Docs spreadsheet?

It can handle economic decisions within an organization using democracy, or multi-sigs to a few trusted individuals. It's also connected to Web 3.0, so you have all of the benefits of being within the ethereum ecosystem.

Sorry I meant richness of the local ecosystem. Big mammals in particular.

That isn't a bit weird, that is outright creepy and borderline cyberstalkish. I wonder what you have done before a first date.

I totally support the idea people who deny climate change should not reproduce. For two main reasons: first, to save the environment and, second, to improve the human gene pool. I don't expect them to agree, however.

>second, to improve the human gene pool. Yeah, everyone who disagrees with me is wrong and we should prevent them from reproducing. /s I fully believe in climate change but your opinion that eugenics is part of the solution is out in left field and incompatible with the values of most people on this planet to put it charitably.

I probably should be more explicit when I joke.

The oceans have a mass 1000 times that of the atmosphere. So if they were predicting 2C increase in the heat of the atmosphere wouldn't that be .002 deg Celsius in the ocean? Can you even measure that give the vastness of the ocean?

It's more complex than that. To heat up by those 2C, water takes over 4 times as much energy as air does. On the other hand, most of the warming happens in the upper layer of the ocean, which is a big issue because it messes with the ocean's circulation.

So when I said that the ocean has 1000x the mass of the atmosphere, I did the math earlier to get the total mass of both. That is a different calculation than the below per unit of volume measurement.

Sea water has a mass of ~1000kg/m^3. Sea level air has a mass of 1.2kg/m^3. How does it only take 4 times as much energy to heat up a cubic meter of seawater than a cubic meter of air? Wouldn't it be ~820 times as much?
