GEO4990 ¨C The Earth System

Course content

The lectures will deal with the basics of the earth system with an emphasis on interactions between its components (atmosphere, hydrosphere, cryosphere, biosphere). Observed changes in the state of the earth system will be presented. Current Earth System Models will be introduced and their capabilities and limitations will be discussed. Projected future climate change based on multi-model simulations will be highlighted.

Learning outcome

After completing this course, you will

• have gained insight into ongoing and projected changes in the Earth¡¯s climate and associated uncertainties
• be familiar with the methods used in climate science
• be familiar with the concept of the Earth System and key processes governing interactions between its main components

Admission to the course

Students admitted at UiO must?apply for courses?in Studentweb. Students enrolled in other master's degree programmes can, on application, be admitted to the course if this is cleared by their own study programme.

Nordic citizens and applicants residing in the Nordic countries may?apply to take this course as a single course student.

1. Students in the following categories (random order):
   • PhD candidates at the Department of Geosciences
   • Students admitted to the following programme option:
     • Water and Climate (programme option)
2. Other PhD candidates, visiting PhD candidates, and master's students in Geosciences, other programme options
3. Master¡¯s level exchange students and other master¡¯s level students at the MN Faculty
4. New single-course students at the master¡¯s level

Applicants will be ranked by the number of ECTS credits within each category:?all applicants within category 1 are ranked before applicants in category 2. If there are space limitations in the course, available places will be given to students selected randomly among those with the same amount of ECTS credits.

Teaching

The course is taught weekly. The teaching consists of interactive lectures with active participation by the students and a model practical. An?oral presentation?of topics in the subject field will count towards the final grade.

A model topic report must be handed in after the model practical and approved before the final examination.

Attendance at the first lecture is compulsory. Students who fail to meet are considered to have withdrawn from the course unless they have previously given notice to the course responsible.

We reserve the right to change the teaching?form and examination of the course in semesters where 5 or fewer students have been admitted.

Examination

• All mandatory activities must be completed and the model data report must be approved before you can sit the final exam.
• An oral student presentation?counts 50% towards the final grade.
• The final oral examination counts 50% towards the final grade.
• Both the oral student presentation?and the final examination must be passed separately?in order to pass the course.

Mandatory assignments are valid for 5 semesters starting from the semester they were approved the first time.

It is possible to take the exam up to 3 times. If you?withdraw from the exam?after the deadline or during the exam, this will be counted as an examination attempt.

It will also be counted as 1 of the 3 attempts to sit the exam for this course if you sit the exam for one of the following courses:

• GEO9990 ¨C The Earth System
• GEF4400 ¨C The Earth System (continued)
• GEF9400 ¨C The Earth System (continued)
