We have a moral responsibility to save wild places like the arctic refuge for future generations, and that is why our country has remained committed to its protection for nearly 50 years.
Remember, the Arctic didn't have any ice. And the Northwest Passage was wide open. They were raising grapes in Scotland for God sakes, had a huge winery. Iceland was a farming community. As some of the glaciers retreated they found villages that were covered with ice.
The fact that the Arctic, more than any other populated region of the world, requires the collaboration of so many disciplines and points of view to be understood at all, is a benefit rather than a burden.
For humans, the Arctic is a harshly inhospitable place, but the conditions there are precisely what polar bears require to survive - and thrive. 'Harsh' to us is 'home' for them. Take away the ice and snow, increase the temperature by even a little, and the realm that makes their lives possible literally melts away.
This journey is not over. Our education initiatives have so much momentum, and we're committed to sharing even more stories from the Arctic when we return.
If you ask me who the members of the Rolling Stones or Led Zep or the Clash were, I'd be able to tell you every member. But I couldn't name a single member of Arctic Monkeys.
The Arctic National Wildlife Refuge is a unique and biologically special place that should be preserved.
Like the canary in the coal mine, the climate changes already evident in the Arctic are a call to action.
We're constantly re-evaluating the potential for life. We're finding it where we didn't think it could exist, such as volcanic vents and other extreme conditions like under arctic ice. We're finding life in these incredibly harsh and dynamic conditions, so we're having to re-evaluate our own ideas of what's possible on this planet alone.
The most important thing for people to know about the governance of the Arctic is that we have a chance now to act to maintain the integrity of the system or to lose it. To lose it means that we will dismember the vital systems that make the Arctic work. It's not just a cost to the people who live there. It's a cost to all people everywhere.
