Final class grades including the final exam are posted under the Grades link. Please check your grade. If you see a problem let me know ASAP, as I will submit official grades in a couple of days. I wish you all a nice summer break!

Saturday, April 30:
Class Grades not including the final exam are posted under the Grades link. The letter grade shown is the grade you will get in the class if you do not take the optional final exam. The grade is based on your weighted class average using the gradescale A: 88 and higher, B: 77 and higher, C: 66 and higher, D: 53 and higher, E: lower than 53. The score shown in the column "To Raise Grade" tells you what you need to score on the final exam to raise your letter grade one letter higher than is currently shown. You can scroll down on this page to see discussion of how the optional final exam affects your class grade. If you have any questions about the grading or the final exam, then please ask them in class on Monday. After discussing the grades at the beginning of class on Monday, we will spend the remainder of Monday and Wednesday's class preparing for the final exam. I suggest that you bring your four inclass exams with you to class next week. If you are satisfied with your grade and have no interest in taking the final exam, then you do not need to attend class next week and I wish you a nice summer.

Class Notes / Important Dates:

There is no textbook for this course. Lectures will be based on the reading material posted under the Lectures Link and additional material that will be distributed during lectrues throughout the semester. I expect that each student read over the relevant reading material before the lecture is presented in class. This is important because the you will be famaliar with what I discuss in lecture and better able to understand it.

Important dates, such as homework deadlines, exam dates, etc., will be posted in the class calendar.

Academic Integrity:

The University of Arizona's Code of Academic Integrity, Code of Conduct, and Student Code of Conduct will be strictly followed. All students are responsible for knowing the codes and abiding by them. Please see Academic Integrity Policies for University of Arizona Students.

Accessibility and Accomodations:

It is the University's goal that learning experiences be as accessible as possible. If you anticipate or experience physical or academic barriers based on disability or pregnency, please let me know immediately so that we can discuss options. You are also welcome to contact Disability Resources (520-621-3268) to establish reasonable accommodations.

Four homework assignments will be given periodically during the semester. The first is a 500 mb forecasting assignment, which will be available during the second week of the semester and due around February 4. The next two homework assignments will be short problem sets that may include simple calculations and will be due around February 10 and March 2. The last homework assignment is a short opinion essay on global warming, which will be due around April 25. The sum of all four homework assignments is worth 20% of your final class grade. A breakdown is given below.

Homework Fraction of Class Grade
Homework #1 -- 500 mb Forecasting Assignment 5%
Homework #2 -- Problem Set 4%
Homework #3 -- Problem Set 4%
Homework #4 -- Global Warming Essay 7%

Your homework assignments will be graded on the quality and clarity of your English as well as their content. No cheating, fabrication, facilitating academic dishonesty, or plagiarism will be tolerated (see University of Arizona Code of Academic Integrity). The research paper and perhaps some of the homework assignments will be filtered through Turnitin. Homework assignments turned in late will incur a grade reduction of 10% per day.

All homework assignments will be available on the class web page. You will be notified in class and with an announcement on the class homepage when homework assignments are posted. You will be given plenty of time to complete assignments.

Research Paper:

A research paper on the subject of the United States adopting an emission control policy will be required for each student. Information about the paper is available under the homework link . I will discuss the research paper in class during the second week of the semester. Please read over the assignment sometime before that.

The research paper will account for 20% of your final class grade. It is due on or before March 9, which is during the week before spring break. I strongly suggest that you begin to work on your paper long before the due date. The paper accounts for a significant portion of your final grade. As an incentive to begin early, there is an optional assignment, which is due by February 3, in which I ask you to specify your topic and provide a few ideas for arguments on both sides of your issue or topic question. You can earn up to 5% extra credit on your research paper for this assignment. Information is available under the homework link .


There will be 4 in-class exams and a final exam. Exam grades account for 60% of your final grade. Each in-class exam will account for 15% of your final grade. The exams will consist of a mixture of multiple choice and short answer questions. The in-class exams are not comprehensive in that the questions concentrate on material covered since the last exam. However, it is expected that you are familiar with some of the basic concepts covered early in the semester. Exam dates are shown in the class calendar.

Questions from previous exams will be made available on the class web pages.

The final exam is optional. If you decide to take it, the final exam grade replaces the lowest of the grades of your previous exams (even if it is lower). Thus, if you do poorly on one exam or miss one exam, you can make for it up by taking the final. Your final exam score will also replace your second lowest exam score (only if higher than your second lowest exam score). Therefore, if you take the final exam it will count for at least 15% of your final grade (by replacing your lowest exam score) and 30% of your final grade (if you score higher than your second lowest exam score). The final exam is comprehensive in that it covers all of the material presented during the semester.

Final exam is Friday, May 6 from 10:30 - 12:30 in the regular classroom, ILC 125.

Exam Policy:

You are expected to study and understand material covered in class during lecture as well as to read the relevant material from the class notes. Exam questions will be taken from both the in-class lectures and the reading material included in the class web pages.

Please contact the instructor (preferrably via e-mail) as soon as possible if for an unexpected reason you are unable to be in class for an exam. A make-up exam will be arranged with sufficient proof. No make-up exam will be given unless you notify the instructor BEFORE missing the exam in class. In general, I would prefer make-up exams to be taken before the exam is given in class.

Grade Scale:

Your final grade will be curved and therefore depends on everybody else's grades. However, the grade scale will not be any more difficult than A(90%); B(80%); C(70%); D(60%).
