Global Warming Revisited (A)
Is there statistical evidence of global warming? This case presents two sets of real global temperature data, one from the Met Office and another one from NASA, and asks students to assess if the data indeed support the belief that temperatures have been rising over the last 150+ years. The case is open-ended-it provides the data and references to some popular press articles on the subject. Also available is a B case that presents three sets of analysis typical for MBA students-an efficient starting point for class discussion.
