Read this interview with NASA's Dr. Gavin Schmidt, who answers five of the most common questions about climate change that he has encountered. As you watch, listen for answers to questions that you or your students still have about climate change. Take note of how Dr. Schmidt refers to "averages" and "decades-long trends" while referencing data as the basis for his and his colleagues' assumptions.
