I was recently on a tour of Latin America, and the only regret I have was that I didn't study Latin harder in school so I could converse with those people.

Although I have a variety of obligations, the climate crisis is my central concern.

We all know the leopard can't change his stripes.

Here`s my point. I don`t want you to be in a position years from now where you welcome Hillary Clinton and say actually you did win. It just wasn`t close enough to make sure that all the votes were counted or whatever. Elections have consequences. Your vote counts. Your vote has consequences.

Having cameras follow you is something that requires a little personal adjustment, but you actually do begin to forget they're there. It's impossible to maintain that awareness all the time, and when you're going through an emotional or absorbing experience, you really don't have any spare attention to think, "Got to remember that the camera is rolling."

Anyone who deals with the climate crisis has an internal dialogue between hope and despair, because the challenge is so huge and the danger is so great and the stakes are so high. But I have always resolved that in favour of hope, and actually I'm more hopeful now than I was a decade ago when the solutions were visible on the horizon, but you had to seek reassurance that the technology experts that they're coming, they'll be here.

As I have said for many years throughout this land, we're borrowing money from China to buy oil from the Persian Gulf to burn it in ways that destroy the future of human civilization. Every bit of that has to change.
