I am convinced that climate change represents a historic opportunity on an even greater scale.

The parties with the most gain never show up on the battlefield.

Most of you didn't think that helping people share books would be a subversive act...Yet the fact is that you have chosen a profession that has become radical.

And that is what is behind the abrupt rise in climate change denial among hardcore conservatives: they have come to understand that as soon as they admit that climate change is real, they will lose the central ideological battle of our time—whether we need to plan and manage our societies to reflect our goals and values, or whether that task can be left to the magic of the market.

The net is more than an organizing tool - it has become an organizing model, a blueprint for decentralized but cooperative decision-making. It facilitates the process of information sharing to such an extent that many groups can work in concert with one another without the need to achieve monolithic consensus.

It doesn't have the ability to think rationally this economic model. It thinks like a drug addict: 'Where can I get my next fix?' It doesn't learn wisely. Any kind of measure of natural wisdom would be: you make a mistake, you correct it the next time around. But a drug addict feels terrible... and then says: 'I want more'. Unfortunately we have an economic model that thinks like a crack addict.

But we need to be very clear: because of our decades of collective denial, no gradual, incremental options are now available to us.
