China’s population has reached a plateau https://ourworldindata.org/explorers/population-and-demograp...

...because they killed millions of girls...

Who is 'they' here? Certainly there was a one-child policy. I don't think it could be said that the consequence of female abortion and infanticide was the intention (or even an expected consequence) of the policy.

It seems that many people in the comments are set on demonizing the country. For this I think better points to raise are the ethnic cleansing of the Uyghur 'reeducation' program, or the usurping of peaceful autonomous neighbors like Tibet and Hong Kong (maybe Taiwan later). But none of this has anything to do with obligations around CO2 emissions, which they are addressing more than any country on the planet, as I've commented elsewhere:

Ouch! They’re estimating 131 kt of methane! That’s equivalent to approx 3.93 Megatons of CO2 (in terms of its global warming impact over a century) or roughly equivalent to that of a small country like Iceland or Malta annually.

How much ∘C of change in global temperature does this translate to?

Short of China and India voluntarily holding themselves to the same standards as Western Europe and the US for free, we are not going to avoid catastrophic global warming.

Who knows how to handle a billion refugees?

There will never be a billion refugees. Climate change is slow enough that humans and nature will adapt.

India is a peculiar case because they're, so so so affected by climate change that it's suicide NOT to stop emitting on such a large scale. Yes we're all susceptible to climate change effects but India, that place gets next level hot.

This is very true. Unfortunately India also houses 1.4 Billion people, most of whom are poor, and any attempt at policy change to limit industry quickly results in poverty-related mortalities by hundreds of thousands, if not millions.

We’re not going to make it are we?

We will but not at our current numbers. Rich countries will suffer the most.

Absolutely wrong. India, China and the more polluting poorer countries are the ones who'll always suffer more.

With >300 AQIs in most highly-populated areas, dirty water from rivers almost all of which are hazardously polluted, combined with a tropical climate that's already hot enough to kill thousands of people from heatstroke alone in summers - pollution-related misery in US and Europe isn't anywhere close enough to that in India. It just doesn't get called out because Indians have bigger existential concerns (many of which go directly against climate-friendliness).

Why do you discount export emissions? Is it forced on them against their will or they don't profit from it? Shall we also adjust for things like how much of their emissions could have been green, etc?

I've heard people argue that its both too aggressive and too conservative. I'm in the too conservative camp, we need to figure things out sooner than 100 years and the risk of a feedback loop is high with methane. Its fine to assert that a single number doesn't capture the nuances of the situation. But we have to keep in mind that 1) the heat trapped by the methane stays trapped even after it has decayed 2) methane c…

>1) the heat trapped by the methane stays trapped even after it has decayed Not really. It would be present, but not trapped. Absent other factors, that would mean earth is above its equilibrium temperature and would cool once methane loss permits it to radiate heat more effectively. Either that or it shoots us in the face with a clathrate gun. There's really only one way to find out.

Let’s not find out if there’s a clathrate gun coming for us? Please?

What are the material requirements for this proposal?

I am not well versed but my impression is it’s essentially a bunch of tin foil and the main impediment are geopolitical reasons and cost to orbit, which SpaceX has been and continues to improve.

Okay, so having gone down this path I can tell you it is impossible. To reduce the output of the sun by 2% at L1 would require 20 MM tons of metal. In order to launch that much tonnage we would have needed to start launching mass 500 years ago. And that assumes no loss of material over time, which would mean even more launches.

It is not feasible.

Per capita doesn't mean shit when their actual gross is way higher.

Per capita is a proxy for discussing how much emissions they need. If you're not considering anyone's need, then you're basically telling them to go kill themselves and they'll likewise completely ignore anything you have to say. If we ignore China's/India's needs and what they actually can do while talking about what they should do, then the whole discussion is a waste of time.
