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.
