What is, and isn't, settled about climate science.
An interesting debate on climate change, between Hadi Dowlatabadi, Canada research chair and professor in Applied Mathematics and Global Change at the University of British Columbia, and Richard Lindzen is a professor of Meteorology at the Massachusetts Institute of Technology.
One of the key points to come from this debate is that the climate is incredibly complex, and therefore, making predictions based on 'models' of climate change is unlikely to produce accurate results. A well reasoned debate by a couple of scientists with real expertise in the area.
Very professionally hosted by journalist Steve Paikin.
It is worth noting that this debate dates from 2010. It would be interesting to see what effect developments since then have had, though I don't think it would affect the underlying principles outlined in this video.
