The only upside to this is that “Katla” is easier to pronounce and type than “Eyjafjallajokull.”
Another upside is a massive oil surplus shold hit the market and cause my pump prices to go down some in the future (if this keeps up). I have a friend in the aviation industry and he said they are down 500 million gallons of aviation fuel sales since this started.
Of course...that's a real drag on the world economy. If the big one goes...its even worse.
