What is the most entrepreneurial country in the Middle East today? It's Lebanon. Which country has no oil or gas? Lebanon. The same was true of Israel, the same was of Bahrain. You could see a real gradation. Turkey, for instance: no oil and gas, very entrepreneurial. You can either dig your future out of the ground or you can unlock the potential of your people.

Today, natural gas now outstrips coal as the leading provider of electricity in America. If this is as big as people believe it is, natural gas will soon be powering trucks and marine ships. Maybe even standard commercial cars that people use at home through compressed natural gas, other gas to liquids. The potential is there for more energy independence by America and a reliance on cleaner fuel - natural gas emits half as much as coal, in terms of carbon emissions. That's a real bounty.

Iraq may still have a decent outcome...but even if it becomes Switzerland, we overpaid for it.

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.

You'll know the green revolution has been won when the word 'green' disappears.

Golf has an ambivalent relationship with the environment. On one hand, it's a great preserver of open spaces. Golf doesn't pave the world - it helps to green the world. But the downside is, it uses a lot of fertilizer, pesticides and water. And this is in a world where we know that synthetic fertilizers and pesticides are toxic, and water is more and more scarce. Golf could do a lot more.

If we don't have a more serious energy policy, the difference between a good day and bad day for America from here on will hinge on how the 86-year-old king of Saudi Arabia manages...change.
