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…

The parent comment said high school which is compulsory, free, and a very low bar. Our nation and world is largely being wrecked by the malicious on behalf of the stupid. Having some bar doesn't seem unreasonable.

The fact that you read my comment and decided to clarify and double down is immaculate for my point.

Have you taken any class ever on disenfranchising events in history?

Also worth mentioning for those in these neighboring threads, the impulse to blame dysfunction during hard times on a particular minority of society has a name, you can read more about it here

China is in no way energy independent. Their fossil fuel imports are extremely high and not decreasing.

China's gasoline use is down substantially. Industrial use is up, but much of that is re exported via plastic etc.

Right, that's exactly the point. Regardless of the consequences, worldwide fossil fuel consumption will continue increasing. Those stable organic molecules with energy rich chemical bonds are so damn useful for everything that enables modern industrial civilization and there is no substitute.

Everyone who can hear this has already heard it. Those who continue to pretend it is not happening are either deliberately deceptive so they can continue to make money from fossil fuels or unable to change their minds when faced by evidence due to identity politics.

My impression is that almost no one denies the warming itself, just the link to greenhouse gasses. That link is unfortunately much harder to prove than rising temperatures by itself. The proof is there nonetheless, but it's easier to cast doubt on it, and that's what certain groups have been doing.

> My impression is that almost no one denies the warming itself, just the link to greenhouse gasses. That link is unfortunately much harder to prove than rising temperatures by itself.

The link to greenhouse gases is not hard to prove. We've got satellites that can measure global radiation inflow and outflow and see what the difference is. We can also measure this at various levels within the atmosphere, and at the surface of the land and oceans. We can see where outgoing radiation is getting caught and we can see what frequency bands of outgoing radiation is getting caught.

We know the frequency bands that get reflected, absorbed, or pass through for all the gases in the atmosphere and can see that the gases causing the problem are the greenhouse gases.

We can also see that the increase in greenhouse gases is mostly from burning fossil fuels. We can see this by looking at the isotope ratios in the C in greenhouse gases.

Cosmic ray bombardment in the upper atmosphere produces carbon 14, which is radioactive with a half live of 5730 years. It disperses throughout the atmosphere and becomes part of anything that regularly incorporates atmospheric carbon or exchanges its carbon with atmospheric carbon, including all living things.

Everything humans do in significant amounts that puts greenhouse gases in the atmosphere other than burning fossil fuels has carbon with about the same isotope ratio as that of the carbon in living things. Even when we burn a dead forest to clear it out the isotope ratio is close to that of living things, because of that 5730 year half life for carbon 14.

It is only when we burn fossil fuels that we put carbon into the atmosphere with almost no carbon 14. They came from living things but have been dead long enough for hundreds of half lives to pass.

The isotope ratios in the excess greenhouse gases show that it is mostly carbon 14 free. There are natural processes that can dump carbon 14 free carbon into the atmosphere such as volcanoes and other geological processes. However, (1) the increases in carbon 14 free greenhouse gases matches very closely with the amount of carbon we've been emitting from fossil fuels, and (2) and monitoring of volcanoes and other natural sources doesn't find nearly enough to account for more than a small amount of the increase.

> The issue seemed to completely drop from public discourse during the Biden presidency Biden signed into law the largest investment in clean energy in US history, dwarfing everything that came before. Half the economy was trying to get their hands on some of that stimmy.

Both were true, the IRA handed out a lot of money to green projects at the same time the administration quietly greenlit a massive boom in oil production. (The Biden administration issued more new drilling permits than either Trump administration).

The dinosaurs did great with a bit of difficulty, too!

They did so well, they lived to tell the tale. Or squawked.

Yeah their descendants/relatives taste delicious. It worked out for the best.

Very exciting to live in an apocalyptical era. I'm looking forward to discover which one of the several global threats to humanity will put us down first.

Famine, the perennial classic. And after famine, the war to clean up the stragglers. Fun :)

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…

China is massively building solar, wind, hydro, and nuclear, and also has by far the largest network of UHV transmission lines (and are building many more) so that they can get electricity from the regions with the most solar and wind to the more northern heavy industrial areas.

They are also the leader in producing and exporting solar and wind equipment, and in driving the prices down, to make it easier for other countries to address climate change.

They are also the biggest producer of EVs in the world, and the biggest exporter of EVs.

They are doing better at doing something about climate change than any other country, both due to what they are currently doing for themselves and for the countries they export to and in their ability to make long term plans and reasonably stick to them.

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.

Not mysterious, just slow and expensive.
