We believe that we live in the 'age of information,' that there has been an information 'explosion,' an information 'revolution.' While in a certain narrow sense this is the case, in many important ways just the opposite is true. We also live at a moment of deep ignorance, when vital knowledge that humans have always possessed about who we are and where we live seems beyond our reach. An Unenlightenment. An age of missing information.

what sets wilderness apart in the modern day is not that it's dangerous (it's almost certainly safer than any town or road) or that it's solitary (you can, so they say, be alone in a crowded room) or full of exotic animals (there are more at the zoo). it's that five miles out in the woods you can't buy anything.

I can't tell how moving it is to open my email and see a picture of 1,500 Buddhist monks and nuns in the Himalayan kingdom of Ladakh forming a human 350 against the backdrop of the melting glaciers. This is not their fault, and yet they're stepping up to be part of the solution.

Absent the net, we certainly couldn't have organized in 190 countries around the world. It's no substitution for face to face interaction - that's why we have "days of action" where people are in real contact with each other - but it's the cheap (and low-carbon) way to do an awful lot of the planning and organizing. And we can build, for $20k, a website as good as one Exxon can build for $20 million.

In 50 years, no one will care about the fiscal cliff or the Euro crisis. They'll just ask, "So the Arctic melted, and then what did you do?"

Speaking for me, I think the odds of bankrupting Exxon are pretty small, but I think the odds of politically bankrupting them are higher. I think if we can use this as a vehicle to get out the analysis that these guys have 3-5 times as much carbon in the ground as the most conservative government thinks would be safe to burn, then that politically stigmatises them, makes them into the rogue industry that they are.

A world where one tenth of the population gets to be extremely wealthy, and six tenths very poor, is not, in the long run, a stable place.
