There are people who say, "God is in complete control of everything that happens, and if the Earth is getting warmer, then maybe God intends that." Well, no. God intends for us to take responsibility for how we treat God's creation, and if we choose to use the thin shell of atmosphere surrounding our planet as an open sewer for 110-million tons of global-warming pollution every day, the consequences are attributable to us. And if you are a believer, as I am, I think God intends for us to open our eyes and take responsibility for the moral consequences of our actions.

When it comes to climate, we can all make a big difference. At the most basic level, don't let denial go unchallenged and win the conversation on climate.

In the United States of America, unfortunately we still live in a bubble of unreality. And the Category 5 denial is an enormous obstacle to any discussion of solutions. Nobody is interested in solutions if they don’t think there’s a problem. Given that starting point, I believe 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.

Airplane travel is nature's way of making you look like your passport photo.

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.

For a free country to continue thriving, there have to be regular reforms, because any society, any economy that stays in place, you're going to see repeated attempts to exploit the openings for twisting policy to the advantage of those who already have wealth and power.

What changed in the United States with Hurricane Katrina was a feeling that we have entered a period of consequences.
