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.

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

Nuclear war is overrated. Too focused to really damage distributed systems, too hard to start, too few working nukes. Many of the old rockets on all sides likely won't even fly correctly. Now drop world shipping via blockades and active war zones, and the industry collapse would be worse than anything Sarah Connor saw.

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…

A very bad idea, leading to the authocracies and despotias like clockwork. A small relief is to see the authors of the initial segregation getting banned too eventually, but it is too late to fix anything. "Tovarisch Stalin, a terrible mistake has happened!"

I've shifted my mindset to abandon this idea that humanity will survive forever, or that we should strive to live as long as we can. Intelligence is a scarcity and it cannot overcome the majority of people that are incredibly stupid or ignorant. So accepting that we are doomed relieves some of the stress. I won't have children to worry about their future, either. I still live my life in such a way that minimizes my i…

Humans won’t get wiped out, not by global warming atleast. It’s just going to suck and a lot of us will die.

Eh, I’m not convinced it won’t be an extinction event. We need a pretty narrow band of CO2 and Oxygen to live. Unclear if a lot of plant life dies off if it takes us with it

A troll response I presume. Or perhaps sarcasm without the indicator.

Not a troll comment. China produces as much or more CO2 as much as the next 5 countries combined. It's logical to start with the king of greenhouse emissions if you want to stop global warming.

China is bringing online a stupendous amount of renewables. They’ve blown through their own targets on solar energy deployments. With where batteries are headed I suspect their CO2 emissions will drop much faster than expected. Already they’ve hit peak coal and it’s on the way down

Nothing? China is solving the problem on their own. They already make substantially less carbon per person that most of the west. If we want to be like China it's a simple proposition: be OK with Manhattan project level investments in power transmission from places that have lots of renewables to places that need renewables.

Climate is determined by total CO2 output, not per capita. That’s a real problem, because China, and all the poor countries in Asia and Africa aren’t going to stop increasing their CO2 output per capita until they reach western standards of living.

Except that they will stop. China has already stopped, because they’re bringing up renewables for new capacity. In 5, max 10 years it will be ludicrous to spin up a fossil fuel power plant. Solar power is already cheaper than coal and prices are dropping like a stone as China ramps production capacity / techniques/ process.

we don't need evidence Earth is warming, because it's happened before humanity, and it will happen after we're gone. We need evidence that we're poisoning ourselves and the planet. Global warming's only accomplishment is giving the poisoners a pass when it was debunked. Private jets and climate change, choose one.

No need to troll here, HN crowd can read so it’s not going to be effective.

You are welcome to read.. any paper on the subject and educate yourself.

> 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.

  Across the world, according to BNEF, the cost of grid scale battery packs has fallen another 45 per cent in 2025 following a 40 per cent fall in 2024. The UK-based energy think tank Ember has now also reached the same conclusion, underlying its unexpected impact on solar power.
from: https://reneweconomy.com.au/the-plunging-cost-of-battery-sto...

citing: https://ember-energy.org/latest-insights/global-electricity-... and similar reports.

Resource prices for batteries did spike at various times in the past, this had more to do with opening and then closing a lot of production sites by mining companies than with any real meaningful supply issue.

Urban grid scal battery parks are on the rise globally, industrial parks have always had special status and can still concentrate modern efficient peaker turbines and buffer storage to bridge, if applicable, and use any general daytime excess.

Even the crotchetiest and most out-of-touch people I know basically accept that the Earth is warming now. They just either disagree on the cause or proportion. Some people just naturally resist hyperbole or sensationalist rhetoric, and I find it very helpful to reframe the argument from doom and gloom and fire and brimstone to something more realistic and grounded: "The longer we put off doing something, the harder a…

The problem with Pascal's wager logic is you have to change your behavior based on all kinds of crazy low-probability events. You must worship every god, be an AI-doomer, a climate-doomer, a nuclear-doomer. Pascal's wager is generally agreed to be logically unsound, so it's somewhat insane that we've revived it in all these modern contexts. If you believe in it, at least be consistent and sacrifice a goat to Zeus eve…

In this case, it's not exactly like Pascal's wager because there is plenty of scientific evidence of disastrous consequences of not believing in climate change (and preparing accordingly). There's no evidence to suggest that a non-belief in God will send you to hell.

Unfortunately, I can imagine the ignorant Americans who don’t realize that all those poor people want SUVs too. You know who doesn’t talk about climate change? Anybody in my family in Bangladesh. They want to live like Americans.

The US can't even get countries to enter trade agreements anymore, because it's throwing around threats of large tariffs and annexation of others' lands. The world could drop the dollar as the reserve currency, something that was gradually happening but is now accelerating. If the US starts trying to force other countries into climate action without taking into account its own contributions, the US will likely cut ou…

The US defines the terms of the vast majority of global trade agreements and there’s no indication that will ever change. Americans get it — global academia hates Trump and to some extent America itself. In a way it’s understandable because you all seem to believe in your “right” to pick winners and losers. The world doesn’t actually work that way.

Trump in his first term gave the Pacific over to China, who now defines terms over there. In his second term, Trump is cutting the US out of leadership in Europe, leading to growing economic trade agreements that exclude the US.

You seem to think these solid critiques about the inherent weakness of Trump are somehow mere partisanship, rather than the actual unwinding of US leadership around the world.

I'm not part of global academia, I'm just a consumer of news that is willing to listen to things outside of a partisan bubble. The world is shifting away from the US, to the US's detriment. We have an exceptionally weak president who acts like what a weak person imagines a strong person is like, and it's scaring off all our allies.

> In a way it’s understandable because you all seem to believe in your “right” to pick winners and losers. The world doesn’t actually work that way.

I do not know whatyou mean by this, you think I'm picking winners and losers? The US is picking winners and losers? Global academia is picking?Picking either antecedent does not allow me to find any meaning in your sentence.
