Having traveled for 45 years in the Arctic, what I've seen the last 15 years is shocking. We need to finally face up that we have an issue here and we need to get back to solutions.

Within 10 years it will be impossible to travel to the North Pole by dog team. There will be too much open water.

I don't think there's any way we can save the polar bears.

If we could cut carbon dioxide emissions by 80 percent over the next 20 years we could perhaps prevent this. If we continue burning fossil fuels as we are today in the very near future (the ice shelf) will slip in (the ocean).

An incredible experience and humbling all the way through.

If there is, I haven't seen him yet.
