Fake news has been around as long as news has been around.

It took me a bit to realize how big the changes have been in the last decade. In so many places - electricity from solar and wind is cheaper than electricity from fossil fuels, and now the batteries are coming down in costs very quickly. So it's very exciting news that needed to be told.

It's as if we think the laws of physics are subject to debate and amendment and political contributions can sway the laws of physics.

Atheists have just as much of a right to the public discourse as any ... people of any religious faith in this country.

If we walk down the sidewalk of any street in America a significant number of the people we pass by, if we dug into what they're going through in their lives, they're carrying burdens that they don't talk about but they're extremely heavy and painful. And so, one of the secrets of the human condition is that suffering binds people together. And when you go through something agonizing, others who know what you're feeling because they've been through it will so often reach out to you and connect with you, and give you strength and lift you up.

Humankind has suddenly entered into a brand new relationship with our planet. Unless we quickly and profoundly change the course of our civilization, we face an immediate and grave danger of destroying the worldwide ecological system that sustains life as we know it.

You know, in physics there's the old law for every action there's a equal amount of reaction. Sometimes that's true in politics. If somebody's out there making nonsensical statements, but wielding power behind them a lot of people say, "Well, I need to react to that." I think that's happening.
