TED TALK:
I consider it my life's mission to convey the urgency of climate change through my work. I've traveled north to the Arctic to the capture the unfolding story of polar melt, and south to the Equator to document the subsequent rising seas. Most recently, I visited the icy coast of Greenland and the low-lying islands of the Maldives, connecting two seemingly disparate but equally endangered parts of our planet.
