Thank you, Chair.
My first question is for the AG, and then if anybody else can answer this question, I'd love to get some insight into it. It is with regard to greenhouse gases and accountability for the environment and environmental programs. I'm trying to understand—just to back up, when you watch the weather on TV at night, you see there's a cold front coming from the far north and there's warm air coming from the south, etc.—if there is any possible way that you know of to measure the effectiveness of environmental programs to reduce greenhouse gases, when we really only occupy half of one continent. The air of the whole planet moves around at all times, so is there ever going to be a way we can actually accurately measure the effectiveness of such programs?
