I do genuinely believe that the political system is not linear. When it reaches a tipping point fashioned by a critical mass of opinion, the slow pace of change we're used to will no longer be the norm. I see a lot of signs every day that we're moving closer and closer to that tipping point.

The insistence on complete certainty about the full details of global warming-the most serious threat we have ever faced-is actually an effort to avoid facing the awful, uncomfortable truth: that we must act boldly, decisively, comprehensively, and quickly, even before we know every last detail about the crisis. Those who continue to argue that the appropriate response is merely additional research are simply seeking to camouflage timidity or protect their vested interest in the status quo.

I saw the logarithmic growth of computer power.

The Bush administration works closely with a network of rapid response digital brownshirts who work to pressure reporters and their editors for 'undermining support for our troops.'

There is an air of unreality in debating these arcane points when the world is changing in such dramatic ways right in front of our eyes because of global warming.

You know there's an old african proverb that i made up: "If you want to go quickly, go alone. If you want to go far, go together."

Fear is the most powerful enemy of reason.
