Sometimes I walk into a situation and I know somebody is going to provoke me - not maybe, I know he will provoke me - I know he will provoke me! And there are times when I simply refuse to be provoked. And the other times you have to use that superior knowledge to carry on at work without distraction, and don't allow yourself to be distracted.

If we can come up with innovations and train young people to take on new jobs, and if we can switch to clean energy, I think we have the capacity to build this world not dependent on fossil-fuel. I think it will happen, and it won't destroy economy.

Some have suggested that ideally there must be some international body that would treat areas like the Arctic as a global commerce, a bit like the way we treat the sea. It doesn't belong to any particular country, but to all of us, but I'm not sure some of the powerful are ready for that sort of solution.
