The 'New Yorker' asked me to shoot a story on climate change in 2005, and I wound up going to Iceland to shoot a glacier. The real story wasn't the beautiful white top. It ended up being at the terminus of the glacier where it's dying.

Each of us can and must shift our behavior according to our ability. For some, that means changing diet, shopping locally, or putting solar panels on their house. For others, it means using their voice to inspire transformative change.

I've been to the Himalayas a half a dozen times and I love it. I'm just kind of tired of going literally twelve time zones around the world. I would rather go six time zones and get to Iceland or whatever it is.

In some cases, I allow the edge of the set, the edge of my own artificial, artistic imposition, to show up because I don't want to hide from that. I want to acknowledge that there is a living human and a living eye and a living mind and a living heart responding to what's going on out there.

I've got at least two major project ideas that I've been chewing on for several years in my head and I've been trying to resist them both. But I have learned over the years that when they don't go away and they're still in there, you probably have to resign yourself to the fact that you're going to do something about them.

I was raised a Catholic as a boy and went to a Catholic boys' high school, a private school, and kind of drifted away, candidly, in my latter teen years. I consider myself deeply spiritual but not in an institutional, religious kind of a way. In Catholicism, we're surrounded by these images of martyrdom and doing penance and doing some suffering to achieve what you're trying to achieve. And I certainly embedded that in my psyche and I have lived that very effectively.

I personally spend the majority of my time by far on outreach and education and fundraising and administration.
