> the planet is fucked The planet will be fine. It will be different, but that's a normal thing in its 4 billion year history. Whether it will be habitable for humans is a different question. I suspect we'll adapt (like we did for the last ice age), but I'm no expert. On the bright side, more heat and CO2 means more arable land and better growing environment. Veggies and grazing animals are all I need to get by, food wise.

More heat and CO2 means a higher sea level, which will lead to the loss of arable land, not gain

  I've been unable to find a source either way. Can you help? Just looking casually at topo maps and assuming the worst case I've seen (all land and sea ice melts, resulting in sea water rising 250'), the land we'll lose in coastal regions and major river basins is smaller than what we'll gain near the poles. Farming just Antarctica would probably produce enough food to feed the world several times over. Edit: This isn't to say that worst case scenario wouldn't displace high percentages of the population or that that isn't a major issue; however, it's not an insurmountable obstacle given the gradual nature of the change.

    Antarica is problematic since it is completely dark 4 months out of the year... and completely sunny the opposite 4 months.. and even then isn't it just rocks underneath that ice.. you would need to bring in soil etc.. but if all the ice melts will that even be above water at that point?

    Farming just Antarctica would probably produce enough food to feed the world several times over. I'd bet a paycheck that there's no top soil worthy of the name under all that ice. Same with when people yuk it up with, "we'll just farm Canada!" Have you seen the dirt in British Columbia? I don't think that soil could grow anything other than more dirt. (Though Manitoba and Saskatchewan would probably do better, dunno.)

      You don't know what you are talking about. Some of the richest soil exists in the Canadian North. I have lived on a farm and planted and raised vegetables on a Canadian farm for multiple years.

People are misunderstanding George Carlin standup sooo much. Yes, "The Planet" will be fine. The ball of molten iron will be fine. It's just that current ecosystem will die out, but apparently it's "fine". We will adapt probably, but billions will die. A simple hypothesis - let's say due to the global warming rice crops will fail globally. Just imagine how many people would be affected and how many nuclear wars started for the remaining resources :) .

  What climate change-induced mechanism could cause a global rice crop failure? Would it also cause global failure of grain, corn, beans, potatoes, etc? The hypothesis seems so far fetched to me as to be dismissible out of hand. I can understand how, over a period of years, farms near the equator may become less tenable and land farther from the equator more arable, but, at the scales I've seen (single digit average degrees up over the next 100 years), we should be able to account for that. Edit: I don't know the Carlin bit you refer to. Link?

    As for the rice crop - afaik it requires a lot of water and right temperatures. If the temperatures will rise a lot, then crops will weaken and increased droughts will cut water supply for the fields. Famines are very possible I suspect in far future. Importing food from the north is possible but not very probable. First because north would also suffer, just differently, second because the population in question is insanely huge (whole Pakistan, India, Bangladesh, East Asia etc.) I don't think enough grain for example can be imported to supplant a loss of a staple crop like rice. And just where this additional grain can be raised in the north? Suitable farmlands are already in use for agriculture. And new lands are either in bad terrain or in bad climate zones. The standup I've referenced: https://www.youtube.com/watch?v=uHgJKrmbYfg https://www.youtube.com/watch?v=uHgJKrmbYfg I've seen way way too many folks on the right who take it at face value, literally. Even his not so subtle references that humanity will die out don't phase people with an agenda.
