1. Why was an international treaty (Montreal Protocol) to limit the destruction of stratospheric ozone negotiated in 1987 if it is true that ozone is a greenhouse gas? a) stratospheric ozone has little GWP b) stratospheric ozone absorbs UV c) stratospheric ozone emits UV d) none of the above 2. In the graph, radiative forcing 5000 years ago was less than at present because: a) [CO₂] ppm was less than at present b) [CO₂] ppm was greater than at present c) the greenhouse effect did not yet exist d) humans were not present on earth Carbon Dioxide (ppm) 10000 350- 300- 250 10000 a) small cars would be driven slower and more afely b) that would permit the earth's ozone layer to recover c) less carbon dioxide would be emitted per mile driven d) particulate matter pollution would gradually decrease Time (before 2005) 5000 1800 1900 2000 Year 400 350 300 3. Driving more fuel efficient automobiles would slow the rate of global warming because: 0 Radiative Forcing (W m²)

**Educational Text with Graph Analysis** **1. Why was an international treaty (Montreal Protocol) to limit the destruction of stratospheric ozone negotiated in 1987 if it is true that ozone is a greenhouse gas?** a) stratospheric ozone has little GWP b) stratospheric ozone absorbs UV c) stratospheric ozone emits UV d) none of the above **2. In the graph, radiative forcing 5000 years ago was less than at present because:** a) [CO₂] ppm was less than at present b) [CO₂] ppm was greater than at present c) the greenhouse effect did not yet exist d) humans were not present on earth *Graph Explanation:* The graph illustrates the changes in carbon dioxide (CO₂) levels, measured in parts per million (ppm), over a span of 5000 years leading up to the year 2005. The y-axis on the left represents CO₂ concentration, while the right y-axis indicates radiative forcing in Watts per square meter (W m⁻²). The historical trend shows a significant increase in both CO₂ levels and radiative forcing, indicating a strong correlation between them. A smaller inset graph zooms in on the last two centuries, highlighting a sharp rise in CO₂ concentrations and associated radiative forcing in recent times. **3. Driving more fuel-efficient automobiles would slow the rate of global warming because:** a) small cars would be driven slower and more safely b) that would permit the earth’s ozone layer to recover c) less carbon dioxide would be emitted per mile driven d) particulate matter pollution would gradually decrease
