Dr. Mathews: While we do agree that climate change is occurring. We are still debating what to call this. Certainly we have seen natural changes in the temperature and precipitation patterns in the past. The big debate is this anthropologic related do to mans activities or changing land use, the removal of the forests, from occupation or crops growing or is it perhaps a very natural event that is occurring as we have seen previously in the history of the planet. So we are still going to debate this. There are still a lot of interested parties however, saying that we don't know enough and that you don't want to make too many decisions that are going to impact the well being economically of the United States when there is so much uncertainty.
