What Do the Survey Data Say?

Based on the evidence you have collected and summarized, form a testable prediction about climate change, using the following guiding questions.

• Does your data set reveal any compelling evidence of change?
• Based on your experiences looking at various kinds of data (satellite, local observations) and trying to connect these to global warming, is one source of data more reliable than another?
• What are the strengths and limitations of each kind of data?
• Are there are good reasons to pay attention to both sources of data?

Share your prediction with the class. Also, discuss whether this activity has helped you understand why climate change has at times been a controversial topic in the news and national politics.
