I don't think this is likely to happen at all. You're right that climate change takes time etc. I guess I was thinking about that chaos we had recently when snow ( very little snow) brought part of the country to a halt (well the M1 anyway).

I figure if catastrophes and TEOTWAWKI is going to happen there's nothing I can do about it so there's very little point worrying about it.

The general approach to most situations here on the forum appears to be get trained and try to have the right tools at the right time. Sometimes this involves storing large amounts of stuff. As someone who can't store huge amounts, I guess I'm curious as to other solutions to things...

So although I absolutely agree that this scenario isextremely unlikely, it got me thinking....
