Questions on CO2 in the Troposphere and O3 in the Stratosphere.
1. How does the concentration of CO2 vary with height in the troposphere and stratosphere? How about O3?
2. Why do we care if the atmospheric concentrations of these gases change?
3. Suppose there is a slight increase in global mean temperature. How does the total mass of plants on the earth change? How does this change the plant consumption of CO2? How does this change the atmospheric CO2 concentration? How does this change the global mean temperature? Is this a positive or negative feedback?
4. What is the 'Ozone Hole'?
5. Suppose there is a slight decrease in stratospheric ozone at the South Pole in local autumn. How does this change the local absorption of solar radiation? How does this change the local temperature? How does this change the amount of polar stratospheric clouds? How does this change the local amount of ozone the next Spring? Is this a positive or a negative feedback?
