Course Description:
ATOC 1060 focuses on the role of the atmosphere and oceans in determining the earth's climate. Our goal is to use descriptive analyses to develop an understanding of the basic processes that determine the earth's past and present climates. We will compare natural variations, such as El Nino and volcanoes, with those caused by human activities, and examine the socio-economic, political, and ecological impacts of these variations. Although a basic understanding of the weather will be assumed, there will be some review of the most important concepts from ATOC 1050 that carry over into this course.


Goals:
To develop an appreciation and basic understanding of the factors contributing to the complexity and diversity of the Earth System, both natural and anthropogenic ("influenced by mankind"). To begin to explore the possible solutions to environmental problems and how those solutions are linked to local, regional, and global economic and political issues.

Course Format:
I emphasize understanding concepts over memorization of facts. Classes will be devoted to discussion of the main points and ideas that are addressed in more detail in the textbook and in additional material, such as readings from newspapers and magazines and provocative videos, such as the Frontline episode 'Hot Politics.' Therefore, you should come to class prepared to talk about your reaction to assigned reading. The Earth System is a highly readable book that comprehensively and accurately deals with the science of the Earth System, especially the natural and anthropogenic forcings and subsequent responses. It covers a great deal of material, and it is difficult to master all of it in a one-semester course. But through group discussions, we can cover the relatively easy topics quickly, and we can start to delve into the more difficult issues.


We will cover the same material that is presented in the larger lecture sections, but we will do it in a very different way. We will focus on how information necessary to understand global environmental problems is obtained, interpreted, and presented, as well as on discussions of various questions raised during the reading in in-class conversations. Consequently, you will be expected to have completed the assigned reading before each class.


Assignments and Grading: The primary homework in this course will be weekly in-class or take-home written assignments based on the reading and in-class discussions. These will be worth 25% of your final grade. There will be two midterms that will each be worth 20% of your final grade, and a final that will be worth 35%. Although each successive exam will test concepts presented in the most recent section of the course, there will be questions that require proficiency in the previous sections. Therefore, it will be important to correct any mistakes from previous exams. Some exam questions will be based on material covered in these projects and subsequent in-class discussions.

Your final course grade will be determined by three exams (75%), and homework/writing (25%). The final grade cuts will be no higher than A-/B+ (90%), B-/C+ (80%), C-/D+ (70%), D-/F (65%) (that is, anyone who gets 90% or higher is guaranteed no lower than an A-, 80% no lower than a B-, etc.).

Expectations

Come to class!! It is important that you come to class regularly. It's probably safe to say that it will be extremely difficult to get a grade higher than a B- in this class if you miss more than 3-4 lectures. The material presented in class will highlight the important issues presented in the book, but classes will not simply repeat what is in the book. By discussing the issues in class with your fellow students, you will gain a much better understanding of the important points and you will develop a greater appreciation for the complexity of the issues and variation in viewpoints. We will also work problems that will help you with the lectures and projects. Please come prepared to participate and bring a calculator.
 

Read the book!! It is not practical for me to cover every detail of the phenomena we will study during regular class sessions, and it is virtually impossible for me to know what concepts are difficult for you if you can't tell me where you are stuck in the reading. Even I get stuck on some points.

Ask questions and participate!! I encourage you to ask questions at any time. I don't mind being interrupted (politely) if something I've said isn't clear, and especially if I've made a mistake (which does happen now and then), and it is important that you follow the arguments of your fellow classmates. If you're not comfortable asking a question during class, please do so afterwards or during office hours, as this will help you to gain more confidence in your understanding of the material.

Participate and interact!! I like to have an interactive classroom. I refuse to talk at students for a whole class period, and I can recall how dull it was to have someone talk at me when I was a student. So, I will ask questions of the class; we'll work on problems; and we'll have discussions about things that are controversial. Participation in a requirement! Civility and cooperation are essential elements in the classroom. This means encouraging one another during discussions and working together on problems.
