You see that pale, blue dot? That's us. Everything that has ever happened in all of human history, has happened on that pixel. All the triumphs and all the tragedies, all the wars all the famines, all the major advances... it's our only home. And that is what is at stake, our ability to live on planet Earth, to have a future as a civilization. I believe this is a moral issue, it is your time to seize this issue, it is our time to rise again to secure our future.
Believe in the power of your own voice. The more noise you make, the more accountability you demand from your leaders, the more our world will change for the better.

Civil disobedience has an honourable history, and when the urgency and moral clarity cross a certain threshold, then I think that civil disobedience is quite understandable, and it has a role to play.
The fate of mankind, as well as religion, depends on the emergence of a new faith in the future. Armed with such a faith, we might find it possible to resanctify the earth.
Distributed intelligence is the key to the advancement of human civilization. Dictatorships, communist countries, monarchies in the past all eventually collapsed because of their inefficiency in moving information.
Today I challenge our nation to commit to producing 100 percent of our electricity from renewable energy and truly clean carbon-free sources within 10 years.
The mountain glaciers in every region of the world are melting, many of them at an accelerated rate, threatening drinking supplies - drinking water supplies and agricultural water supplies. We have these record storms, drought, floods, fires, three deaths (ph) in the American West, climate refugees beginning now, expected to rise to the hundreds of millions unless we take action.
