22. Describe the difference between climate and weather Figure 3.9 400 15 10 -350 -300 Temperature relative to today (F) CO2 concentration (ppm) 250 :-10- - 200 -15- 150 0 -20 400,000 300.000 200.000 100.000 Years before present Figure 3.9 Carbon dioxide concentration and global temperatures (red) over the last 400.000 years from e core data 23. Consider figure 3.9 above when answering the following questions a. How does the present concentration of CO2 in the atmosphere compare: i. With its concentration 20,000 years ago? T. With its concentration 120,000 years ago? b. How does the present temperature of the atmosphere compare: i. With the 1950--1980 mean temperature? it. With the temperature 20,000 years ago? ii. How does each of these values compare with the average temperature 120,000 years ago Do your answers to parts a and b indicate causation, correlation, or no relation? Explain
