Ironically, if temperature gets to a high degree enough, so much water vapor, methane and carbon dioxide will be on the atmosphere capturing heat (which will eventually escape), but more importantly, reflecting it on the upper atmosphere layers, that we will freeze to death before even feeling the burn LMAO 🤣
Water vapour is quite good at absorbing heat, and it insulates the atmosphere too(it's often warmer at night if its cloudy), would it reflect enough heat for that sort of cooling to happen? Sounds like something that would take a lot longer to happen than the time it will take to get too hot for us to survive without living underground or something.
