Goals
      The main goal of this course is to give you a solid introduction to the earth as a unified climatic system, to the forces that act on the various parts of that system (such as oceans, atmosphere, biosphere, and solid earth), to the ways in which those parts are currently changing, and the extent to which those changes are affected by human activities. This is a difficult task in principle because many of the observations that serve as raw data are too short, such as the one or two centuries of direct measurements of temperature. Therefore, we are forced to guess at many important questions that we would really like to answer unambiguously. We will therefore spend much of this class dealing with principles such as how the earth gets its heat, redistributes it, stores it, changes it into different forms, and eventually releases it back to space. We will then examine some factors than can perturb these processes, including a changing sun, changes in the earth’s orbit, variable ocean currents, drifting continents, and last but not least, human effects on the atmosphere and possibly via the atmosphere to climate.
      A secondary goal will be to develop skills in critical thinking. Throughout the semester, we will constantly be working with chains of reasoning and evaluating the multiple explanations possible for various observations. For example, one of the most important questions will be the simplest possible one: “Is the earth warming?” The answer to this basic question may not be as obvious as it seems, for reasons that may surprise you.

Materials
      The text for this course is The Earth System by Lee R. Kump, James F. Kasting, and Robert G. Crane. This is a recent book that is excellent. It is full of valuable interdisciplinary information, and will be a challenge for you to master. If needed, we will supplement it with materials from other sources, including the Worldwide Web.

Format, homework, exams, grading
      We meet TTh at 11 a.m. for the full 75 minutes. I expect you to attend every class and to be prompt. Typically, we will first discuss the reading for that day and then introduce the material to be read for the next class. Discussion will often be lively. Questions are encouraged, and differences in viewpoints will be respected provided that they can be defended logically.
      We will cover three chapters of the book every two weeks until we finish Chapter 15. This plus the midterm exam will take 10.5 of the 14 weeks (i.e., 3/4 of the semester), and will give an overview of each of the main section of the book. We will then use the remaining 3.5 weeks (1/4 of the semester) for in-depth reviews of selected topics and integrating the material. Because you will be reading the material 50% faster, I will drop the weekly homework assignments and concentrate on class discussions. It is now more important than ever that you read the material before each class, so that we can all discuss the main points and you can ask about things that you don't understand. Absences and lack of preparation will lower your grade. You should be prepared to spend up to three hours outside class for each hour inside. Working significantly less will diminish the value of the experience and lower your grade. Don't say I didn't warn you!
      You will learn the material, and I will help. I will not necessarily cover all the material in the lectures. Instead, I will emphasize the key points and the difficult ideas. You will fill in the blanks.
      There will be a midterm exam on Thursday 7 March and a regular final exam on Friday 17 May, 11:30 a.m.–2:20 p.m. The final grade will be based 30% on the midterm, 50% on the final, and 20% on class participation.
      This class has its own web site, whose home page is given above. It will contain the assignments and answers, answers to the hourly exams, copies of any handouts, and notices. You should check there at least weekly.

Most important of all
      I am here to help you learn valuable things about global change and how to think about it. Help me make this a great educational experience for all of us.
