Few of us ever get to know if what we do for the planet or the species is really useful in the long run, but just the possibility that it might be should be enough. For now, anyway. As an old prog rock fan I appreciate the Bowie reference. Lately I've been using Eno on the freeways with the words "Save the Humans." http://www.freewayblogger.blogspot.com/2013/05/save-humans-los-angeles.html It's quite an arresting image, and a fantastic, even prophetic album if you consider side one as "before science" and side two as "after".

I have a lot of banners of the Arctic from space I've been using on the freeways here in California: http://freewayblogger.blogspot.com/2012/12/one-thousand-signs-plus.html If anyone has any good text to go with them, please send it along. ("Now disposable for your convenience" has been up over a week in a spot passed by 325,000 cars per day) Don't know if this changes anyone's attitude or behavior much, but it's a hell of a lot of fun.

I've managed to reach a lot of people using this method: http://www.freewayblogger.com/wakeupandsmellthepermafrost.htm enough, in fact, so that when you type "wake up and" into google, "Smell the permafrost" is the first suggestion... at least out here on the west coast. Anybody got any slogan ideas about the Albedo Effect?
