Our video of the week is a bit longer than usual: it's a full-length lecture by Dr. Richard Milne from the University of Edinburgh entitled "Critical Thinking on Climate Change: Separating Skepticism from Denial." Dr. Milne offers a clear and compelling explanation of the difference between true skeptics (who help move science forward by asking tough, legitimate questions) and deniers (who cherry-pick data, rely on false experts, and use other questionable techniques to advance a viewpoint in the face of scientific evidence).
For more discussion about what constitutes true scientific controversies and how they are resolved (or not), read our module Ideas in Science: Scientific Controversy.
For more about how visuals, such as graphs, are used and misused, check out our module Data: Using Graphs and Visual Data.
