In case you missed the show: This is a short debate between Bill Nye (the science guy) and Marsha Blackburn (politician) that was held on Meet the press. It was a disappointing debate to me. The format was wrong for this and didn’t give Bill Nye nearly enough time to present the evidence in an informative way.
Having debated with deniers in the past, I know that you generally can’t change their minds on the subject. They either deny that it exists, call it a conspiracy or just blow it off as not being a serious problem. However, there maybe some people in the audience that are simply unaware or misinformed about the scientific evidence. In that case, the better you explain it, the more people are likely to accept climate-change as fact.
