Students will analyze graphs to help understand the affect of CO2 concentrations on temperature. They will discover how graphs can be set up to help prove a point and occasionally mislead the uninformed.
Students know how of the greenhouse effect works and its positive affect on Earth. They should know that scientists and environmentalists are worried about the effects of increasing the levels of CO2 on Earths climate. The international scientific community has come out strongly with warnings to the public and governments of countries that they are concerned about greenhouse warming. Resistance to cutbacks of CO2 come from a variety of sources and often use the same data as scientists, but in a different format. Data can look very different depending on how it is displayed in a graph. It can be altered to show different amounts of time or a different scale of magnitude.
