I wish you were going to be my student. Jeepers, motivation!
Richard Alley is a good writer and you'd get a head start on understanding climate: http://www.amazon.com/Two-Mile-Time-Machine-Abrupt-Climate/dp/0691102961/ref=sr_1_1?ie=UTF8&qid=1319155474&sr=8-1
You could start reading Earth magazine: http://www.earthmagazine.org/
I guess you could buy the textbook for the course and read that.
In climate science, you can always assume the temperature anomaly is based on the average 20th century temperature. Once you look at a couple of real pieces of science, you'll see it time and again.
Like in the title of this submission.
CO2 measurements from thousands of years ago are based on proxy measurements. Basically, ice cores, and some plants and animals that incorporate elements of the atmosphere or ocean also incorporate the ratio of CO2.
So scientists go to places like Greenland and Antactica, and drill down a couple of miles (literally). Then they examine the tiny air bubbles frozen in the ice to see what the concentration of CO2 was back then.
Then, to verify these numbers are correct, they go to the deep ocean, and take out cores from thousands of years ago. They look at the fossilized shells of ancient plankton, examine its chemical makeup, and can figure out CO2 concentrations. They then compare these with tree ring records and other proxy measurements to make sure they all line up.
The Two Mile Time Machine is a great book on climate and ice cores, if you're interested.

There is a really good (and surprisingly entertaining) book that talks all about ice core science that can answer all your questions. Long story short, we can tell a lot from ice cores. http://www.amazon.com/The-Two-Mile-Time-Machine-Climate/dp/0691102961 Hope that helps!
