I have noticed that I switch night and day cycles during summer because it's too hot to function in the day.

The earth is getting hotter each year due to capitalism. With how capitalism works, capitalists aren't going to slow down or give a second thought for nature. At a certain level AC won't be enough and workers will end up collapsing or dying... Which lowers production, so I think that maybe in like 5 or 10 years (if not now already) we'll see some push for night shifts because it's colder in the night, burning the earth without affecting productivity. Will also limit chilling to lit up private properties that require payment or full of consumables like a Walmart because it's safer than idk sitting in a public park at 3 am. This will probably get spun around as a revolutionary good thing or something.
