I would imagine that one could come up with a stage criteria to help in the understanding of what changes will take place, all the way to a worst case scenario...
Something like the following...
Stage 1
Stage 2
Stage 3 :The stage of not being able to "stay put" would be about stage 3 when food security has more or less failed, Governments are on the verge of collapse, insurance is impossible to get and mortgages fail every where. Money looses any meaning
and a barter economy is starting to take hold. Nuclear war is ever possible and the energy grid fails. Transport and other logistical needs are not able to be met. Looting and general anarchy is endemic.
Stage 4 : Abandoning any individual accommodation due to food, energy and personal security requirements, seeking shelter such as defended stadiums, and other organized spaces.
Stage 5: The need to maintain sustainable air conditioned spaces becomes essential as the heat and humidity outside of the shelters makes it virtually impossible to go outside with out specially designed equipment and close to impossible to live inside.. Stadiums will need to be roofed, Hydroponics established. Energy from local diesel moving towards renewable, scavenged solar panels etc. Commincations and logictics have to be generated for all shelters to communicate. Surviving frequent peak conditions with frequent (>cat5) violent storms and storm surging ocean waters is a must.
The lack of forward planning will make all this really painful leading to only a few surviving through to later more sustainable stages.
just ideas and thoughts...
The above is just a quick just now thought out list. Perhaps thrashing out a more properly thought out staging list would be helpfull
