I've read before that a large portion of the warmest parts (Uttar Pradesh/Bihar) of India actually haven't had its temperature rise much because of coal power, farm burning and dust in general (a lot from construction) the particles block basically protect them against the sun. Putting India in a spot where if it would cease relying on coal power in 30-40+ years it would cause the temperature to rise.

What a choice: heatstroke, or chronic respiratory disease?

  Basically given the choice of one kills in hours and other in decades. Can we try to take option c?

There is nothing stopping them from releasing sulfur dioxide into the air to have the same effect in an engineered and superior manner. Also, various surfaces can be painted white to reflect sunlight back into space. Trees also can be planted, and forests restored. The good thing about green energy is that one there is a sufficient amount of it, it can also be used for extensive indoor air conditioning.

  > The good thing about green energy is that one there is a sufficient amount of it, it can also be used for extensive air conditioning. The heat doesn't vanish with AC, at least not unless you use a very expensive deep-underground well as a heatsink instead of the open air. Even if everyone has AC indoor - the air outdoor will still be too hot and, most likely, humid, with all the expelled heat from the ACs added on top of that. Animals won't stand a chance, especially wild ones, and humans that absolutely have to work outside (e.g. policemen, firefighters, EMS) will be just as impacted. We have to face the reality: large parts of the globe, impacting billions of people, will be unable to support human and a lot of animal and plant life during the summer months if climate change continues at the current pace in a short enough time that most people reading this text will eventually witness this.

      During the day once the room is cold my minisplit spends around 800w keeping the room cold. Say, what happened to those 800w? Where does that go?

      It's already silly coming from the US, but jumping to the conclusion that a random comment, on a US-based forum, is propaganda specifically for a German political slapfight, is a very funny form of political egocentrism.

      it's the Prisoner's Dilemma - AC helps the individual at the expense of those outside, for whom it is now hotter (can raise ambient air temp by 2-4C). It worsens global warming in how it is powered (on hot days might have to fire up peaker plants using gas) and leaks of refrigerants.

        Yes but as long as there's no international agreement where we either all stop using AC to "save the planet", then individuals will optimize for their survival and comfort, which means using AC. You can't force people to downgrade their lifestyle when they see that only applies to them and not to other people on the planet, making their suffering in vain.

      The second law of thermodynamics implies that one must spend energy as work to move thermal energy up a temperature difference. So the net effect of an air conditioner is to increase the total amount of thermal energy.

I’ve wondered about that. Even in rural towns, the midday sun in India feels “dimmer” on a clear day. Even for the winter, this seems odd as the relatively lower latitude should make for more direct sun. It feels like the soft warm filters used in photography… Outdoor sun normally bothers me greatly, but there sunglasses don’t even seem needed… Not sure what proportion is coal dust, dirt, or wood smoke but something major is definitely going on…
