Create a graph that visualizes the changes in atmospheric
carbon dixoide levels by using the three (3) data points in the article that
provide a date (year) and carbon dioixde level.
Watch the following video clip to learn more about the
significane of the Keeling Curve mentioned within this article. When
finished viewing explain how Dr. Charles Keeling measured atmospheric carbon
dioxide and why the graph shown in the video oscillates every year.
Visit the website www.acespace.org to learn more about
climate change and what you can do in your school and community to help
battle rising atmospheric carbon dioixde levels. You can even request for
someone from ACE (Alliance for Climate Education) to give a presentation to
your whole school.
