Our own Emily Gertz is attending Verdopolis, as well, and will be filing reports on what she finds for Grist (as well as doing a write-up for WorldChanging). Her first day's observations are now online, and are well worth checking out. This paragraph caught my eye:
This good mood is what seems to be different about Verdopolis. It's a gathering where we dispense with arguing the moral imperative of fewer cars and more trees, and instead get on with figuring out how to design the bright green future for our growing cities. It's beyond anger, done with denial, and waist-deep into acceptance. And at this panel, we were accepting that human-caused climate instability has arrived, and making it better is both the right thing to do and a huge business opportunity.
Sounds like our kind of event.
