In order to have the best chance of surviving a catastrophe it is as well to be slightly prepared. Not over-prepared, because events will certainly not pan out exactly how you rehearse them, but at least having physically practised some of the possible response actions. Hence we have periodic fire drills in buildings to check that at least some people have an idea of where to go and what to do.

 What we urgently need as we enter a period of uncertainty and the increased likelyhood of troublesome events is some degree of drill, or preparedness training for people. Perhaps the time has come for a group to take the lead on this and engineer some disruptive, but perhaps non-destructive, events in order to give people a chance to rehearse their responses to changing circumstances.

If these disruptions had a short term environmental benefit then so much the better; so perhaps action to shut down a major airport, or close a major road, or disable a prime communications or energy link could be justified in terms of both its personal value to those caught up in it as well as in its impact in terms of carbon saving - every flight cancelled, every vehicle journey that didn't happen, every hour without power is saving some precious carbon quota.
