Each and every one of us can make changes in the way we live our lives and become part of the solution [to climate change]

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.

The scientific evidence of how serious this climate crisis is becoming continues to amass week after week after week.

Where solar energy is concerned - and wind energy and battery storage and electric vehicles and efficiency technologies - that is what we are now seeing. So, yes, I'm very optimistic, but anyone who works on the climate crisis has an internal struggle between hope and despair. I won't deny that, but hope has always prevailed in my outlook.

I'm old enough to know that a red carpet's just a rug, and I've been able to enjoy the pageantry without letting it go to my head.

The will to act is a renewable resource.

It's a blessing to have work that feels fulfilling.
