I wish I could ask all three of them this question. One of the points that was never fully addressed in any of the interviews was how corruption and overall government inefficiency (more in the administrative sector and in all levels) affected the endeavors in slowing climate change or climate change mitigation. This question is extremely relevant to me because while we heard a lot of success stories in the interviews, we did not really hear about the places where people are not doing enough (at least not in depth); and Brazil is a country known (at least by Brazilians themselves) to have an immense ability to not do things properly. So my two-part-ish question would go something along the lines of: are there any success stories coming from places with historically bad public policy? Be it because of corruption, inefficiency or incompetence from policymakers. Also, if there have been, what seemed to the trigger for it? The overall population, specialists, some great politician, the private sector, the "third sector" or "voluntary sector" (NGOs or other non-profit companies), or some combination of these?
I would likely ask this question to Dr. Dan Kammen, as from his interview it seemed that he had a lot of experience in examining other place's responses or solutions to climate change.
