Course Description

The Arctic region plays a key role in regulating global climate and is in the midst of rapid change, altering physical, biological and human systems both within and beyond the region. This comprehensive assessment of the Arctic climate system begins with an overview of the Arctic's basic physical characteristics and climate. Attention then turns to the atmospheric energy budget, the atmospheric circulation, the surface energy budget, the hydrologic cycle, and the fascinating interactions between the atmosphere, Arctic Ocean and its sea ice cover. Following an overview of numerical modeling of the Arctic system, we explore Arctic climate history over the past two million years. The final segment of the course explores the future of Arctic climate and potential impacts on society, including issues such as increased access to oil, gas and mineral wealth at the bottom of the ocean, commercial shipping and conflict between stakeholders. The course will use the 2ndÌýedition of the instructor's textbook "The Arctic Climate System" and additional materials as needed. It is assumed the student has already taken at least one course in climate science, meteorology, hydrology or physics and has basic mathematic skills and computer skills (an ability to work in Excel).Ìý

Grading, undergraduate students

The final grade is based on 100 possible points. There will be two exams (a midterm and a final, worth 15 points each, collectively representing 30% of the total grade) with short answer and essay sections. There will be 8 homework assignments, worth 5 points each, representing 35% of the total grade (students may drop one homework assignment). These homework assignments focus on quantitative calculations surrounding various aspects of the Arctic climate system (e.g., radiation and surface energy budgets, hydrology, climate, snow cover, sea ice growth, atmospheric circulation). There will also be 10 essay assignments of 500 words each on various topics of Arctic climate, worth 4 points each, collectively representing 32% of the total grade (student may drop two essay assignments). The remaining 3 points are for attendance and effort, assigned at the discretion of the instructor. Essays and homework assignments are due Friday midnight of each week indicated, see D2L for dropbox details.Ìý

Grading, graduate students

The final grade will be based on a total of 130 points. Exams (30 points total), homework assignments (35 points total), essays (32 points total) and attendance and effort (3 points) are the same as those for the undergraduates, but some of the homework assignments will have additional calculations.ÌýThe additional 30 points (to achieve the 130 point total) will comprise a term paper (25 pages, no larger than 12 point type,ÌýnotÌýincluding figures or references) on a topic of the student’s choice. Part of this grade will be based on presentation of the term paper in class towards the end of the semester. The paper itself is due midnight before the day of the final. Essays and homework assignment are due Friday midnight of each week indicated, see D2L for dropbox details.ÌýÌý
