Optional Text: Ruddiman,W.F., 2001, Earth’s Climate: Past and Future, 1st edition: W.H. Freeman and Co, NY, 465 p.

Prerequisite: Introductory geology and meteorology or equivalent (or permission of instructor); senior undergraduate or graduate standing. Intended for students in both the geosciences and science education.

Course Philosophy and Objectives: Climate is interdisciplinary. Our goal is to provide you with a fundamental understanding of how Earth’s climate system works, how climate has changed through geologic time, how to decipher climate archives from the geologic record, and practice in communication.

Readings: Required readings are journal articles, although we have also listed corresponding chapters in the textbook if you decide to purchase it. You are responsible for material covered in all required readings. Journal readings will be uploaded as pdfs on Canvas. Reading primary literature is an important component of advanced education because it requires you to absorb, synthesize and analyze research papers. An online exercise will accompany each non-text reading assignment, due 24 hours prior to the relevant lecture. Further details will be discussed in class.

Term Paper: For your term paper, you should focus on, and research extensively, a paleoclimatic topic selected by you and approved by us. Use existing literature. Project requirements for those enrolled in the graduate levels differ significantly from those enrolled in the undergraduate levels; also, undergraduates may work in teams of two, whereas graduates are expected to work independently. This is a semester-long project with components due throughout the semester; see syllabus for due dates. Our goal is to help you learn to write. For additional help (outside of class), please remember OU’s writing center; for more information visit www.ou.edu/writingcenter. Know the definition of plagiarism, and don’t plagiarize. More instructions will follow soon.Writing is hard; don’t get discouraged.

A Note on Research: Your research on course projects should be extensive, given the level of this course. Go well beyond the web—i.e., to the professional literature (real books and journals). ALL sources, including web sources, must be cited—using uncited material is a form of plagiarism. Good starting points for literature searches are Georef,Web of Science, Geoscience World, and Google Scholar. Access articles free through the OU library.

Exams and Exercises: There will be two exams; do not miss either (no make-up exams). Exercises will be linked to lectures. All homework must be uploaded to Canvas dropbox by due date. Students who plan to observe a religious holiday that falls on an exam or due date should notify the professor as soon as possible to make appropriate arrangements. Contact us at least one week prior to an exam if you plan to take exam in the DRC.

Grading: Readings (20%), Homework (15%), In-class Exercises (15%), Exams (30%),Term Project (20%).

  • Any student who has a disability that may prevent full demonstration of abilities should contact us as soon as possible to discuss accommodations necessary to ensure full participation and facilitate your education. Students must be registered with

the Office of Disability Services (Goddard, Suite 166, 325-3852; www.ou.edu/drc/home.html) prior to receiving accommodations. • It is the policy of the University to excuse the absences of students that result from religious observances and to provide without penalty for the rescheduling of exams and required class work that may fall on religious holidays. • Title IX Resources and Reporting— for any concerns regarding gender-based discrimination, sexual harassment, sexual assault, dating/domestic violence, or stalking, OU offers a variety of resources.To learn more or report an incident, please contact the Sexual Misconduct Office at 325-2215 (8-5 M-F), or smo@ou.edu, or confidentially reported 24/7 at 615-0013.
