I am new as well to the forum AZ and would like to say I lived in Apache Junction, AZ for a few years as well as Manchester, NH (Currently in NM planning a return to NH).
Your comments regarding climate change seem somewhat centered around survivability or preparedness and with that in mind I would have you reconsider a few thoughts. The dessert doesn't offer much in the way of growing without a great deal of soil preparation, the drought there (and here) has been severe for sometime and the proximity to CA in regards to fracking (Ground water / aquifer contamination ) as well as increased earthquake activity are a fair amount of negative factors.
NH on the flip side has a abundance of fresh clean water, snow that can be melted into water, fertile soils, abundant wildlife and earthquakes are not as large a issue (or even as likely).
So in summation a little colder weather vs. some of the mentioned larger issues may be a more prudent choice if the focus is on survivability based on weather changes, unrest or even a EMP (speaking solar)...
However I think the focus of this movement is more centered around liberty, life, freedom and the original American Dream. NH has for many years has had the embers of freedom and liberty smoldering and in today's political climate the need to fan that flame has become a paramount concern. If we continue down our current path climate change will be the least of our concerns because we already know the wealthy, politicians and their minions are preparing for the tide to shift.
Our country is being devastated for the profits of a few while the 99% get buried, pushed out, neglected and driven to homelessness and despair. The only way to change what is happening is for the people to wake up and see that a better way can be had, can work and can be achieved. With the massive amount of propaganda being aired on lame stream media, consumerism and consumption being programmed into the mass population the only way to combat the looming disaster if for a group, coalition or state to illustrate how things can be better.
Liberty is a mindset at the moment with a few UN-programmed, a few awakened individuals but the majority are sheep unable to see the bigger picture. So the example needs to be a glaring, shining and undeniable fact that they can see and realize can happen, is happening and can change the course we are on.
Every movement needs a solid foundation to be launched from and NH has had that foundation for years. The idea is to concentrate the numbers of individuals who can effect change into one area and set the stage for the previously mentioned example.
America doesn't need more millionaires, lawyers and bankers making the rules... It NEEDS idealists, dreamers, musicians, artists, doctors, nurses, and common people making the rules.
Our forefathers knew this and warned us but MONEY has skewed the message, warning and tilted the rules in favor of a handful of individuals. So the vision has in large part been lost and the only way to get it back it to show by example that liberty, freedom and the people governing is the way back to a stable coarse where the class divide is smaller and people can actually live a fulfilling life, without struggle, without wars and poverty...
This project has the right goal (to concentrate our efforts in one area with the best possible chance of success) and if we believe life is more than just following instructions, swallowing lies and propaganda and that PEOPLE make a difference then we need to follow our hearts and make the move for a better future.
Does that mean it cannot happen in AZ, NM or any other state... Certainly not, however the ground work, grass roots involvement and concentration of like minded individuals will take time and considerable effort and time is something very little realize is running out.
The foundation has already been laid and it behooves us to take advantage of that now and start building the momentum now before that all precious time runs out.
NH may not be everyone's cup of tea but I would rather be surrounded by freedom fighters in the cold winter than zombies in the warm fema camps of the south
Just my thoughts friend, I hope they give you a few of your own to mull over
