When our founders created America, it was in the age of the printing press, when individuals could freely join the conversation. And that robust, democratic dialogue more often than not lifted up the best available evidence and asserted what was more likely to be true than not.

At some point, a false belief collides with physical reality.

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." Another reason for the increased prominence of the climate-change issue is the Paris Agreement itself. It's not a small thing when just about every nation in the entire world comes together and makes an historic agreement like this. It's a big deal. And the old cliché "The train is leaving the station" kind of applies.

Americans have the right to have their medical decisions made by them and their doctors, and not by those bureaucrats sitting behind a computer screen hundreds of miles away.

...it is appropriate to have an over representation of factual presentations on how dangerous it is, as a predicate for opening up the audience to listen to what the solutions are, and how hopeful it is that we are going to solve this crisis.

We're putting 70 million tonnes of pollution into the atmosphere every day, trapping an enormous amount of extra heat from the sun inside the earth's atmosphere. It's threatening to push the planet past a tipping point beyond which climate change would be difficult to stop

Every day we put another 110 million tons of global warming pollution into the sky as if it's an open sewer, and it's still building up. And the scientists tell us it's a race against time. We've stabilized emissions globally now for the last three years, but they need to start coming down quickly. We've got the momentum, we've got the wind in our sails, we're gonna win this.
