Duration of the event
I have not seen much focus by the media on the duration of this event.
Even if it just goes on for a few weeks, the effects could be major for Northern Europe.
As has been observed, the event could last years.
What would be the effect of a long and continuous ash fallout for aviation (even at low altitudes)?
I think we're into the realms of science fiction style solutions in that scenario.
Interesting times ahead perhaps.
