    Not in a meaningful timeframe, I think. Even if we get a worst case outcome (say +5°C by 2100, ongoing warming), permanent land ice in Antarctica will likely take many hundreds, or even thousands of years to melt entirely.

    It’s always going to have frozen winters with lots of snow, due to the long dark polar winter… I guess some boreal tundra species could survive that, but farming is probably unlikely to be viable, I would guess.

      Earlier tonight I was watching a video going over sone climate predictions. There was a legit worst case scenario of an ice-free Arctic Ocean as early as 2030. Once one pole goes, it’s hard to see the other tensing frozen much longer

        Sea ice (most of the arctic) is VERY different to land ice (which is most of Antarctica). Check some sea ice maps and ice thickness maps to see the difference.

        Also, the two hemispheres are not tightly coupled over short (decadal scales). The Arctic has been warming much faster than the Antarctic (so far).
