1) How does carbon cycle through the various Earth systems?
2) How do paleoclimatologists study ancient climate change?
3) What are the possible causes of long-term climate change? How has the Earth’s climate
changed over the last 60 million years?
4) What factors explain short-term climatic change? How has the Earth’s climate varied
over the last 18,000 years?
5) Describe how carbon dioxide-induced global warming takes place, and how humans may
be responsible. What effect might global warming have on the Earth?
6) What are some of the likely scenarios for the long-term future of the Earth?
7) What does the author of your text write, at the beginning of the chapter, about geology’s
most significant philosophical contribution to human understanding? Comment on his
statement.
