Oh, good. Just checking; I wasn't sure if you were away from us.
You were talking about something that I think most southerners would not understand the importance of, and that is black carbon. You referenced the Stockholm convention and the “dirty dozen”; I think that's how it was established. For those of us who don't dig deep into these briefs all the time, the dirty dozen was what the Stockholm convention was to deal with.
Within that, within how you see black carbon being dealt with, are we talking about having to have another convention protocol? As you said, there needs to be measurement.
Maybe I'll ask just two quick questions on this. Where does it come from, and how would you propose dealing with it? You've told us what the problems are in terms of the effects of it.
