I'm curious about where we draw the line on questioning scientific consensus.

Take Cliff Mass - he's a professor of Atmospheric Sciences at UW whose research focuses on weather modeling, climate systems, and atmospheric dynamics. When someone with his expertise raises questions about climate science conclusions, should we approach this differently than when non-experts do so?

This raises an interesting question about the role of expertise and scientific discourse: Is there a meaningful distinction between how we treat challenges to consensus from qualified researchers in the field versus those from outside it? Or should acceptance of consensus apply equally regardless of one's credentials?
