Question

Question 4: Don't label the graph, just write down what today's CO2 concentration is.

Question 5: Don't use the graph in the assignment, but tell me which letters label glacials and which letters label interglacials in the attached figure.

DUE: Monday, July 28, 11:59 PM

Greenhouse gases such as carbon dioxide (CO2) and methane (CH4) trap long-wavelength solar radiation in the atmosphere. There is strong evidence that average global temperatures are slowly risking. A likely cause of global warming is the clear trend of increasing concentration of greenhouse gases due to the burning of fossil fuels. The plot below shows the monthly mean concentration of as measured near the summit of Mauna Loa in Hawaii since 1958 (the International Geophysical year).

1) Describe the trend of CO2 over the last 40 years. Has CO2 changed at a constant rate?

2) What is responsible for the distinctive “saw-tooth” (zig-zag) pattern superposed on the overall long-term trend of rising CO2?

3)

4) What is the natural range of variability in the CO2 prior to growth of the human population and industrialization?

5) Where is today’s concentration of CO2?

6) Indicate the times when the Earth (use graph below) was colder (glaciation) and warmer (interglacials). What would sea level be like during these times? Why?
