IMO you're continuing to demonstrate the wrong type of world model, seeing numbers as absolute cut-offs rather than distributions.

The 15% number was being used to demonstrate that wages are not equal — that number is not my free choice, it is not due to me thinking an income of US$1508/year is a magic number below which one cannot have AC, but rather it comes from how that specific income distribution graph was broken down. The underlying reality is (unless all the UBI proponents have missed a huge example), not constant income in each of those boxes; and a separate point that not everyone in any given income category will be able to choose to buy AC simultaneously even if it is available for purchase.

I am going to say that when such events happen today[0], people already die. The question is how often, and how many are impacted at any given time. And given that temperature is a continuum, what implications this has for close-to-threshold conditions where people can live through it just so long as they don't move or stand up, or the even earlier broad transition zone where they can do decreasing levels of labour before being forced to rest (answer: sub-threshold events are more frequent).

> At a 5% real growth rate, income doubles in about 15 years. That is a lot of wealth that they can use to solve this problem.

The average income doubles in 15 years, but no, it's not a lot of wealth — it's starting at a moderately low level, and there's a lot of things that are also important to spend money on, and even if everyone picks AC first and then the rest, a fixed percentage growth for all groups puts most of the numerical growth in the already rich; if you want to argue around this issue, you would need a model that shows different growth rates for different income levels[1] or that the culture is significantly different from how the west demonstrably does things[4][5].

> And approximately 80-90% of living Indians seem to be due to the fossil fuel economy that people are blaming for global warming; so by raw numbers most people are still coming out ahead. The obvious path is to keep going with coal until it runs out.

Er, what? No. Even from the pure energy argument, the obvious answer is "use the cheapest power". That's not coal, and hasn't been for a while now. At least, it is everywhere else, when I tried searching for the Indian prices the pages I was given were clearly written by ChatGPT…

Also for the specific example you picked, "until the coal runs out" would put out enough CO2 to cause measurable cognitive impacts worldwide as humans, unlike plants, do not thrive with more CO2. Nuclear power would also be "green" in this sense, though given the geopolitics of India and Pakistan specifically, I'd hope both would move away from nuclear for reasons entirely out of scope of this discussion and regardless of any optimism about the price of future reactors.

> And the doom case hinges on 85% of the population sitting there and doing literally nothing while 15% fall over and die on the street. You m might believe that is likely, but I think it is implausible. And if it does happen that way, that doesn't seem like it'd sit on my conscience.

It won't sit on my conscience either, just as the grounds for my belief already don't sit on my conscience, though my beliefs are anchored on European culture rather than Indian culture which may well be different.

Specifically with regard to heat issues: "Despite the fact that many European countries activated heat prevention plans during the summer of 2022, the estimation of over 60,000 heat-related deaths suggests that prevention plans were only partially effective."[2] (Also note that Europe has a GDP/capita about fifteen times higher than India[3], which would take 55.5 years of 5% growth to match).

And with regard to "do rich people really help poor people?", using homelessness as a proxy: "The data shows that more than one million properties across England in 2022 were unoccupied (4.01 per cent of all dwellings), an increase of nearly 60,000 homes since 2018."[4] vs "New research from Shelter shows at least 309,000 people in England will spend Christmas without a home, including almost 140,000 children. This is a stark increase of 14%, 38,100 people, in one year."[5]

Now, if you're like me, at this point you're thinking "why isn't Ben giving evidence about specifically Indian heat deaths?": I wanted to, but it seems they don't actually exist in a good quality form, and it's politically divisive within the country: "The Indian Express newspaper reported that one hospital superintendent who’d publicly linked deaths to heatstroke was later removed from his position for giving “a careless statement.” It then quoted a doctor who’d visited the same clinic as saying the causes were unclear. […] Beyond that, though, it’s symptomatic of the parlous state of health services and public data in a country that lacks the means to even know for certain how many people its broiling climate is killing, let alone take measures to help them. […] A common solution to that problem is looking at excess deaths — comparing recorded fatalities with the number you’d expect in a typical year to iron out the effects of reporting bias. […] Even that approach may be inadequate in India, however, because the most basic data on mortality is too patchy. Nationwide, roughly 8% of estimated deaths in 2019 went unrecorded, according to an annual government survey, and only 19% of the total were certified by a medical professional, a step considered routine in most countries."[6]

(Also, "fall over and die on the street" is more likely to be "go home and lie down out of the sun, and still die", as the 'wet bulb' condition is that you can't even survive in a breeze in the shade, and I'd expect people to seek shade and a breeze before the temperature reached true deadly 'wet bulb' levels over the course of any given day. This also means the AC has to be actual AC and not just a fan).

> More electricity fixes a lot of problems simultaneously.

On this we agree.

[0] and they do happen, with increasing frequency, which is why they are in the meme-sphere at all, though caveat the language in the meme sphere often conflates "hot bulb" with all heat-related deaths and that's not actually what the term means.
