Module 1   Case Study Step 2: Sum Up the Subjects
Note: For consistency throughout this activity, we use 2010 as our “current year” because this is the last year for which we have tallied data from weather stations. Subject #1 Subject has lived in the community for _______ years. Subtract the numbers of years lived here from 2010. Subject has lived here since: 19_____ Overall, the subject observed that the climate has changed (circle one) significantly / somewhat / none / they were not sure
********************************************************************* Subject #2 Subject has lived in the community for _______ years. Subtract the numbers of years lived here from 2010. Subject has lived here since: 19_____ Overall, the subject observed that the climate has changed (circle one) significantly / somewhat / none / they were not sure
********************************************************************* Subject #3 Subject has lived in the community for _______ years. Subtract the numbers of years lived here from 2010. Subject has lived here since: 19_____ Overall, the subject observed that the climate has changed (circle one) significantly / somewhat / none / they were not sure
********************************************************************* Step 3: Determine Base-Period Year Calculate the average number of years your three subjects have lived here: _________ average number of years Subtract this average from the year 2010: _________ is your base-period year. You will use this when you go to collect the data for your area.
