I have always been fascinated with those who try to look over the horizon and see things that are coming at us.

If youre a young person looking at the future of this planet and looking at what is being done right now, and not done, I believe we have reached the stage where it is time for civil disobedience to prevent the construction of new coal plants that do not have carbon capture and sequestration.

I'm naturally an optimist, but my basis for hope is rooted in my understanding of human nature.

The ability of big money to shape perceptions - where you have four anti-climate lobbyists for every single member of the House and Senate - is a big factor.

All of us can make changes, but the changes that are most needed are not light bulbs and windows but laws and policies and treaties. So, yes, we are in a phase of this (climate protection) struggle where civic and political action is at the top of the list.

When you're going through an emotional experience and you're focussed completely on what's happening, you can't even spare any attention that the camera's there.

The golden thread of reason that used to be stretched taut to mark the boundary between the known and the unknown is now routinely disrespected.
