Weather Makers - Is the ozone layer a good news story?

Students explore the cause and effect of CFCs being released into our atmosphere, and how a global agreement – the Montreal Protocol – helped to reduce these emissions and (hopefully) stopped the spread of the thinning ozone. Student begin by graphing the average size of ozone thinning for the past 34 years, and then calculate the average amount the ozone has reduced since 2000. Students are then asked to compare CFCs and CO2, and to participate in a debate around the pros and cons of using the Montreal Protocol as a model for managing CO2 emissions.
