Global Warming: Data

Antarctic Ozone Hole

This site from the EPA shows a map (Fall, 2000) in several alternative formats showing changes in the extent of the Antarctic Ozone Hole. The links explain why the Ozone layer is most likely to show thinning over Antarctica. Relatively easy to read and from an authoritative source. This site supports learning to read maps.

Antarctic Ozone

This site provides Near-Real Time and Historical Data related to the extent of the Ozone Depletion in Antarctica. These graphs and plots can be used by students to determine differences in different seasons and allow substantial practice in reading graphs. The teacher may need some additional information to help students analyze some of the graphs, but one that seems very easy to use is the one entitled Ozone Hole Area. This graph provides a look at the extent of the Ozone hole in Sq. Km. over past two years by month.
