Thank you, Mr. Chairman. Let me thank all of our witnesses for their testimony.

What would be the effective price for carbon in order to hit that goal and any schedule in terms of price increases?

I guess the question on the minds of many consumers is not Dr. Hansen's approach a more direct approach to ameliorating that cost impact on a consumer?

What is important is you really need to provide more choices for the American consumer.

I like the carbon price as the tuning knob because it is a stable one with a linear, while in the case of caps, there is too much volatility.

For you, Dr. Ekwurzel, Dr. Hansen has proposed that in order to address the price impact on the consumer, you essentially have a rebate, a 100 percent rebate.

Let us assume that is the path we want to reductions on that schedule. What would be the effective price for carbon in order to hit that goal and any schedule in terms of price increases?

They are using the top public officials of this government to purely play politics, instead of focusing on the challenges the country faces.
