Air is one we hold in common; it has a limited carrying capacity for pollutants and that's being used up by those who pollute the atmosphere. So we have to stop that externality. We would never allow a utility to put their coal slag in a dump truck and back it up to the city park and dump it in unlimited amounts for free. But that is exactly what we do with carbon dioxide and methane.

We need to get our sons and daughters home and their responsibility for the security of Iraq needs to be assumed by Iraqis who will stand up and toe the line for their countries.

When Arnold Schwarzenegger goes to his reward - how's that? That's a crack, but I treat Governor Schwarzenegger well in my book. He's done such great work in California; we'll forgive him one personal habit. Everybody should have one not-totally-CO2-friendly habit they can be forgiven for. So we'll forgive him that one.

With 1 million square miles of the Arctic melting unexpectedly this summer, these are warning signs that we have to act and act now. Our addiction to Middle Eastern oil obviously has security implications, and we think it's about time to be generating Eastern Washington wind energy instead of sending our money to the sheikhs.

The need to help spread democracy and the ability to do that will be much greater if we break this addiction to oil, which gives the oil princes and sultans the power in the Mideast.

Renewable energy also creates more jobs than other sources of energy - most of these will be created in the struggling manufacturing sector, which will pioneer the new energy future by investment that allows manufacturers to retool and adopt new technologies and methods.

On Earth, we still have a beautiful atmosphere that precisely maintains a thermally driven climatic system that shelters, shields and sustains our natural treasures.
