• Wonder what the range of survivable temperature for humans is like compared to, say, cockroaches. Seems like it’d be a lot narrower

    Without heating or air conditioning, it's not great, but just clothing and shelter which we've had for many millennia are good for -40°C to +40°C. Cockroaches are rubbish at low temperatures, you can kill them in a domestic freezer. Some invertebrates can survive excursions down to -80°C, but actually living requires temperatures well above freezing.
