Al Gore claim's there is a relationship between CO2 concentration and global warming. Worldwatch Institute has compiled a dataset on CO2 concentration (CO2) in parts per million (ppm) and temperature (TEMP) in Celsius for the last 159,000 years. The dataset consists of 160 observations, where each observation is the average CO2 and TEMP over each millennium. To verify Gore's claim that CO2 is the cause for TEMP to increase, you decide to do an regression analysis, and here is your Excel output:
