There's lots of room in Northern US, Canada and Russia. Not sure why Greenland and Antartica would be the only living places on Earth. There's also the Rockies, Andes, Himalayas and other mountain ranges. That's some extreme doomerism. I doubt most of Earth will become uninhabitable. Some places will be harder to maintain larger populations and grow crops.

Places without decent soil (i.e. Northern Russia, or high mountains) can only grow food in meaningful qualities if you bomb the soil with copious amounts of fertilizer. Fertilizer production requires fossil fuels and advanced civilization, both of which are not a given in the future.
