Changing temperatures and carbon dioxide
Courtesy of Exploring the Environment http://www.cotf.edu/ete/main.html This graph shows how carbon dioxide levels and global temperatures have changed over thousands of years. How have scientists found all this out? Use the data on the left to produce your own bar charts and graphs. Is there evidence that increasing carbon dioxide levels is resulting in an increase in the average global temperature?
Can you safely base your conclusion on this evidence alone? How have global temperatures and carbon dioxide levels changed since 1997. Use the Internet to update the table. Download the excel spreadsheet
