Question and description
What is the rise in global atmospheric CO2 (carbon dioxide) average over the last 2000 years?

Build a timeline graph that shows the average carbon dioxide in the atmosphere over the last 2000 years, particularly the rise in the last 100 years likely due to carbon emissions by human activity and climate change.
