By themselves, they are not enough; we also need to engage in political action.

All the things that we've done as a species have had a limited scope. We're talking about melting the ice caps, raising the level of the seas dramatically, changing the distribution of every other species on Earth, perhaps wiping out one-third or half of them. The changes at work are geologic in scale. The level of change required to deal with it is enormous, too. It will require change in every country. It will require a degree of global cooperation that we haven't seen before.

I don't know how to make people who absolutely have to be obsessed with paying a week's energy bills... obsessed with climate change... It's very hard.

If we were built, what were we built for? ... Why do we have this amazing collection of sinews, senses, and sensibilities? Were we really designed in order to recline on the couch, extending our wrists perpendicular to the floor so we can flick through the television's offerings? Were we really designed in order to shop some more so the economy can grow some more? Or were we designed to experience the great epiphanies that come from contact with each other and with the natural world?

We've been given a warning by science, and a wake-up call by nature; it is up to us now to heed them.

We use the web to help people organize in the flesh, and then we take the images of those events and put them back on the web to make them add up to more than the sum of their parts.

The essential thing we need to understand is that the climate crisis is not some future threat, but a very present peril, the biggest one humans have ever encountered. Until we understand that, we'll dawdle.
