Every footstep we take, every action has a consequence. We breathe in weather, but we breathe out CO2. We're responsible for weather and for climate.
What people don't understand about the Arctic is that this isn't just about those other people, those Eskimos that have nothing to do with us. The Arctic drives the climate of the whole globe.
In 2007, I received a National Geographic Expeditions Council grant to go around the top of the world and talk to Arctic people about how they've been impacted by climate change.
I started traveling in the Arctic in 1991, so I experienced the ice in winter and spring. The seasonal sea ice, it has a long season. It starts in September and ends in June.
People travel and hunt on the sea ice - in Alaska, they hunt in skin boats for bowhead whales; in Greenland, they hunt with dogsleds. The ice is their highway. The ice is also the ecosystem in which marine mammals and terrestrial animals such as polar bears exist.
