I can understand people having their own reasons for dismissing the facts or the rhetoric. What I can't wrap my head around is the conspiracy thinking around environmentalism. What's so nefarious about clean air and water? I'll never forget when my grandmother walked out of WALL-E because she said it was government propaganda. She is a regular person, not a coal magnate or anything.

You need to understand the political and cultural history. Environmentalism has been associated with leftist, feminist and communist ideology going back to the hippies and the antiwar movement (which makes it easy for many Americans to mistrust by default.) When Trump said he believed global warming was a Chinese hoax (remember that?) he was echoing a belief amongst the right that environmentalism and "global warming…

Interesting. So it's a guilty by association thing. I get that propaganda plays a big role, it just never made sense to me why it worked.

So a green energy revolution sounds exciting to me, but to my grandma it would be a green energy _revolution_, the scary and unstable connotation.

I think many people are unwilling to accept "climate change" or "global warming" because of the following: a) china is unwilling to do anything, and if that's the case, America shouldn't empty its pocket books on this issue. b) this climate change alarmist stuff has caused a climate disaster in the US because all the migration to Electric Only is causing us to use generators all over the place, which is crazy. We sho…

I think the smart money is still on nuclear war, but the competition is getting fierce these days.

I think there's a strong argument for generalized systems collapse. It's a silent civilization killer, could be happening right now!

But which system first? Could be climate, could be financial, could be political (as in "politics is the alternative to violence")

Thank you for sharing this. I think it's important to take a step back and consider the real existential threats that humanity faces like climate change. I am hoping for similar evidence of the doom from AI, but I have a feeling that the AI doomers have ulterior motives.

Another reframing that may be useful is energy security/redundancy. If you have a cheap source of solar panels and batteries, the only downside to installing them all over the country is up-front cost (which pays itself off quickly). The upside you gain is a substantially more robust, less centralized power grid that can continue to operate if something happens to impede your supply of fossil fuels or part of the gri…

Where is this mythical cheap source of batteries? I mean you can go on Alibaba and order cheap 18650 cells in limited quantities but there's an enormous difference between doing that and having enough reliable battery power to keep a nationwide grid supplying a modern industrial economy through several days of bad weather.

> Where is this mythical cheap source of batteries?

They’re made out of rocks. Yes, you have to take steps to acquire and refine the materials, then turn them into batteries. However, the process for doing that is not mysterious.

> My suspicion is that water vapor from air travel is by far the biggest contributor. Have you calculated the water vapor generated from air travel, and compared that to the water vapor already generated by the water cycle? (just normal evaporation from lakes/rivers/oceans/plants) Even as back-of-napkin math, this should be a pretty easy sanity check. I think you're off by a few orders of magnitude here, but I also d…

>> Have you calculated the water vapor generated from air travel, and compared that to the water vapor already generated by the water cycle? I've SEEN the effects with my own eyes. You can also see contrails seeding cloud formation on some days. Then there's the fact that these extra clouds are formed and dissipate on a 24 hour cycle, so part of the day they let in sunlight and part of the night they trap heat. These…

How significant? Give me a number. What percentage of all the clouds in a day come from planes?

I mean, all of humanity has lived in the period between two glacial eras, I don't expect us to go beyond that. This should be clear even to people who choose to ignore the facts about climate change.

We are currently in an ice age.

What would happen if we weren't?

Oh yeah, we'd all die.

Maybe we shouldn't cause that to happen.

I wonder if we should move beyond this messaging. It’s well known to the smart half of the population that climate change is happening. There is apparently some debate on the cause. But this point is mostly irrelevant, it is problem-oriented thinking. By keeping the conversation in the problem-realm you invite troglodytes into the conversation to insert their bullshit. Instead, if we move forward with “presumption of…

Presuming that you yourself have "graduated" (what from is unclear), it's particularly audacious that you make this claim because it shows rather cleanly how poor a marker of quality an education is.

The answer has never laid in ever more elaborate designs to disenfranchise particular members of the population. It's always been in building community.

A community is what helps stabilize, helps tighten up distributions, and wrestles most authentically with the general premise that we are social creatures and only as strong as our weakest link.

If you think you're going to build the perfect society by way of careful electorate curation, I have some unfortunate stories to tell you.
