Rainin: Very interesting, even in this very hard judgement of the riscs from SHTF the danger from all things except food-shortage stops around 1year. Toxic gases stops around 6months-1year. As you point out, this was before all kinds of computer-models and now konsensus is that it will be very much milder consecuenses. This is 6000Megatons so its pretty bad. You can make food from petroleum products with some chemistry, I dont know how far this chemistry is now but humans surviving will make food somehow, maybe nuclear reactors produce electricity and this is used for lighting in greenhouses that produce food. We are not helpless. Is make a print screen of this table. The risc pandemic is low because it will be low population density. You may go crazy but that is something you can fight. One thing is very important, if you beleive there will be an end to this, hope can carry you a very long time.
