I'm passionate about restoring the efficacy of American democracy, making capitalism sustainable, prioritizing advances in technology, and seizing the opportunities to use that kind of innovation to help usher in a new economy that doesn't rely on carbon-spewing fossil fuels.

It's not unusual to find big political shifts that take place beneath the surface before they're visible above the surface.

I tell you that Michael Jackson is unbelievable, isn't he? He's just unbelievable!

I'm not trying to top anything. I'm trying to be useful, to play a positive role, to serve the public interest.

The climate crisis requires a bottom-up, grassroots demand for solutions because the elites in many parts of the world are under the influence of old industry.

Any of us who work on the task of solving the climate crisis have at times an internal struggle between hope and despair. But that's one of the things that connects this climate movement to the previous great moral revolutions, like the civil rights movement and more recently the gay rights movement. So those who feel despair should be of good cheer, as the Bible says. Have faith, have hope. We are going to win this.

Our world faces a true planetary emergency. I know the phrase sounds shrill, and I know it's a challenge to the moral imagination.
