Remember, the difference between the world frozen over, in an ice ball, and the warming period we're in now is just 6 degrees centigrade. A change of just 1 degree can have a huge effect.

I think no country is going to be immune from the Arab awakening because the Arab awakening is driven by deep human longing for dignity, for justice and for freedom. I think that applies to young people in Saudi Arabia as much as to young people in Egypt, Tunisia, or Yemen, or Libya, or Syria. If I were in Saudi Arabia, I would be getting ahead of this and looking for ways to appreciate those aspirations and align my country with them.

Our president's latest energy initiative was to go to Saudi Arabia and beg King Abdullah to give us a little relief on gasoline prices. I guess there was some justice in that. When you, the president, after 9/11, tell the country to go shopping instead of buckling down to break our addiction to oil, it ends with you, the president, shopping the world for discount gasoline.

Scientists tend to focus on what they don't know more than what they do know. And there are a lot of things we still don't know about the climate. But we know the difference between climate variability and climate change, and right now the amount of carbon in the atmosphere is well outside the variability pattern - and that's quite quantifiable.

Every golf course should have its carbon rating on the scorecard, alongside its Course Rating, Slope, par and yardage.

The reason that we are becoming less equal is because of the greater requirements, secure requirements, for a good job. This goes back to the '80s basically, this started changing as globalization and the IT revolution merged, and each started to drive the other.
