What if air travel in the future becomes impossible due to volcanic ash clogging up jet engines?

Two solutions. Reduce cruise altitude to one which would not be affected or find a means of minimizing the effect. The latter would mean to clean incoming air which is not likely with Jets but might be done for piston aircraft.

there are lots of worse issues going on in our international than international Warming greater suitable seen climate exchange. I advise we hassle approximately those issues first. the debate of an upcoming ice age replaced into greater like 40 years in the past and it replaced into quite merely a small team of scientists with a small quantity of conflicting information. The media have been given carry of this concept and ran with it merely to sell further information papers quite. The exhaust trails you notice from intense flying jet airplanes is especially much all water vapour.

Not a very plausible "what if". In that scenario, life in general would become pretty unpleasant as the world began to plunge into global climate change. If it did happen, I guarantee that a way would be figured out to surmount that problem. I suppose you believe in the world ending in 2012 too?

I imagine southern routes would become predominant, with surface transit used to travel north.

I don't know about you guys but I've already duct taped a bunch of my local birds together and mounted a seat in between them. I plan to continue flying.

dude people wouldn't be able to live in a place constantly covered with ash, so no real need to ship there huh?

Then air travel will not be possible.
