CO2 Concentration Before Charles Keeling Measured CO2 Questions

Overview

1. Before Charles Keeling measured CO2, what did scientists think about the CO2 level in the atmosphere?

1. What would the CO2 concentration be in 2100 if we do nothing?

1. Why is the site of Mauna Loa chosen for taking greenhouse gas measurements?

1. Besides CO2, what other measurements do scientists take at the observatory?

5. Please write down the following information for five anthropogenic greenhouse gases:

• 5.1. Name and chemical formula
• 5.2. Lifetime range
• 5.3. Global Warming Potential (GWP)
• 5.4. Sources (Where do these greenhouse gases get emitted?)
• 5.5. How are they related to our daily life?

You can read the material below before class to get prepared for these questions.
