Snow on the San Gabriel Mountains (photo by Jerry Thompson1, CC 2.0 license)
On December 30 of last year (six days ago), my wife and I were in Pasadena, CA visiting the Greene and Greene exhibit at the Huntington Library. It was one of those glorious and rare smog-free days in the LA basin. The air sparkled, you could see for miles in every direction, and mountain range after mountain range was visible – all the way out to the snow-covered San Gabriels. Nowadays, the air is only ever this clear around the Christmas holiday, when the freeway traffic is substantially reduced and a lot of factories shut down for the week. It got me thinking about how the future – say ten to twenty years hence – may be unrecognizable in both dramatic and mundane ways. For example, smog-free days may no longer be rare in LA, once the economy has shifted off fossil fuels. (I suspect the traffic will remain, unfortunately!)
