It is theoretical that northern regions would have the crop growing climate. One thing I have noticed about these formerly cold areas is that the soil buildup after the ice age was extremely slow. The tundra melt is what is releasing astronomically increasing amounts of methane (23 times worse than CO2 as a GHG) in a self sustaining feedback loop. I think the theory will prove, for the most part, to be a false hope. Population growth so far into overshoot, the decline of cheap oil, the vastness of various pollution and depletions, and climate fluctuation is going so fast that implementation times are non-sufficient.
As far as my website Earthshipvillages on some ocean sponsor (blue-ocean, electric-ocean? I forgot), it was 2002 and 3. Very few hits or interest, even though I have written to politicians since 1994 about making eco-construction, Earthship/strawbale independent homes with alternative power and recycling systems mandatory for all new construction, and discussions on villages remote enough and well defended enough to resist cannibal gang attacks. Over genetic erosion limits, several acres of each Earthship outside devoted to orchards, wheat, grazing, and woodlands. With acknowledgment that only a small percentage would actually survive the long haul. Now with beyond worst case acceleration, the entire biosphere's climate would be non-conductive to those necessary orchards, grazing meadows, woods, and grain fields. The water or sunlight or even wind have more of a chance of exceeding limits for power and water for the recycling water systems. Nuclear war fallout would also ruin the grounds and water catchment. Either way, the very minimum is problems with the common outside grounds being able to grow enough with a minimum suffering of one crop failure every three years. So you need more good land and more storage capability sealed from rodents and other thieves. It is better to die at least trying to survive this way, rather than not giving it a go in a good location with enough good hard working, intelligent and tough people. Good luck.<rockon>
