Americans understand that they have no stronger ally, no better friend, than Australia.

Nobody looks at opinion polls with more attention than politicians, but of course you've got to remember that a single poll is a snapshot in time.

The question of whether or to what extent human activities are causing global warming is not a matter of ideology, let alone of belief. The issue is simply one of risk management.

I have always been generous because I know that I have done well in life and I believe it is part of my duty to give back. So I am always been philanthropic.
