I have a sense of mission on this climate crisis, and I'm trying to pour all the energy I have into it. And I hope that I, along with others, can catalyze the emergence of real solutions to the climate crisis. I think we're making a lot of progress. I think we're going to win this, but it matters how quickly we win it. So I'm focused on that.

The age of printed pamphlets and political essays has long since been replaced by television, a distracting and absorbing medium which seems determined to entertain itself more than it informs and educates.

The Congress is virtually incapable of passing any reforms unless they first get permission from the powerful special interests who are most affected by the proposal.

I have felt for a long time that the pathway to solving the climate crisis is through the building of a massive grassroots army of men and women who will go out there and win the conversation on climate, and persuade businesses, and universities, and towns to switch to renewable energy and to reduce emissions. And the big change from ten years ago is that people are way more receptive, not only to the message that we have to act, not only to the message that now we can act, we have the solutions now - that's the biggest change - but also willing to make a commitment that we will act.

As human beings, we are vulnerable to confusing the unprecedented with the improbable. In our everyday experience, if something has never happened before, we are generally safe in assuming it is not going to happen in the future, but the exceptions can kill you and climate change is one of those exceptions.

The spiritual sense of our place in nature... can be traced to the origins of human civilization... The last vestige of organized goddess worship was eliminated by Christianity.

You can say the Earth is flat, but it doesn't mean you're going to fall off the edge.
