Kronos/Qo'nos uninhabitable ruins
Rewatching Kelvin movie 2 (Into Darkness) — Is it ever explained why part of the Klingon homeworld has an uninhabitable zone that looks like it’s going through nuclear winter?
Praxis. It was destroyed earlier in the Kelvin Timeline as compared to the Prime Timeline. You can see the remnants of Praxis when they're flying into Qo'nos. There's a comic book prequel for Into Darkness that shows Khan going on a mission to Praxis to sabotage and detonate the moon.
The destruction is recent and heavily impacted the atmosphere of Qo'nos in both the Prime Timeline and the Kelvin Timeline. Praxis was also originally based off of the Chernobyl disaster so reflecting the destruction as a nuclear winter on the ground feels pretty appropriate to continuing that idea of Chernobyl and showing what it looks like on the ground a little while after Praxis. Then there's the fact that they decided to reflect the Klingons in this time period as being heavily industrialized with a thick layer of pollution covering the planet.
Gotta say though, not sure how I feel about these comments just being dismissive immediately without even looking into the answer. Merely insulting it and saying it is undercooked or that it takes/doesn't provide adds nothing to the discussion or theory crafting. The whole point of discussions like this is to come up with a potential answer, not to throw up your hands and say "They're dumb lol".
Most of Kelvin 2 was undercooked and relied on the other Star Trek 2 to carry the narrative. It would be unsurprising if there was no forethought put into why Qo'nos as uninhabitable regions other than "it sounds cool".
Possibly. If it’s not already established, I wonder if the backstory could be filled in later in an episode on one of the TV shows or something. Maybe they could tie it to whatever eventually blew up Praxis.
Other than that, I’ve read there’s active volcanos on Kronos, so perhaps that area with all the ash falling was once inhabited until an unexpected round of volcanic activity, like a giant Pompeii.
The mystery box only takes, it does not provide.
