When I worked with wildlife a lot in the Eighties and Nineties, I learnt the meaning of patience. And when I worked with trees, I learned the meaning of humility.

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

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.

I have often thought that my work with wildlife taught me the meaning of patience, and my work with the big trees taught me the meaning of humility, and my work with the ice has taught me the meaning of mortality.

Glacial pace is actually an incorrect concept. The glaciers move a lot faster and they react a lot faster than people imagine.

Early in my career I discovered that there was something really special about photographing at night that places your mind on the surface of the planet. You’re no longer just a human being walking around in the regular world. You’re a human animal striding around on the surface of the planet that’s out in the middle of the galaxy. We as a culture, we’re forgetting that we are actually natural organisms and that we have this very deep connection and contact with nature. You can’t divorce civilization from nature. We totally depend on it.

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.
