Lectures: 2 sessions / week, 1.5 hours / session
This course provides students with a scientific foundation of anthropogenic climate change and an introduction to climate models. It focuses on fundamental physical processes that shape climate (e.g. solar variability, orbital mechanics, greenhouse gases, atmospheric and oceanic circulation, and volcanic and soil aerosols) and on evidence for past and present climate change. During the course they discuss material consequences of climate change, including sea level change, variations in precipitation, vegetation, storminess, and the incidence of disease. This course also examines the science behind mitigation and adaptation proposals.
This course focuses on the science of climate and climate change, giving students a broad background in the central concepts and tools of climate science. For example, while nearly everyone has heard of the "greenhouse effect", we will go into some depth on the issue of radiative transfer through gases. We will address such questions as
In addition, we will endeavor to acquaint students with the primary tools which climate scientists use to understand and predict climate. As part of this endeavor, we will use develop and use a hierarchy of models of the climate system, ranging from simple toy models that can be solved analytically to one-dimensional climate models that solve comprehensive equations of radiative and convective heat transfer. Problem sets, issues approximately biweekly, will help develop an understanding of climate science, and a term projects will address some of the pressing issues on climate science today.
A general, mostly qualitative background to climate science is provided by Archer, David. Global Warming: Understanding the Forecast. Wiley, 2011. ISBN: 9780470943410. [Preview with Google Books]
A good summary of the state of understanding of global warming can be found in Climate Change 2007—The Physical Science Basis: Working Group I Contribution to the Fourth Assessment Report of the IPCC. Cambridge University Press, 2007. ISBN: 9780521880091.
This is a discussion-based and problem solving-based class. Some of the class time will be spent solving problems in small groups or in class discussion.
About 60% of the course will be based on problem sets, 40% on the term Project, and also partly based on participation in class discussion.
Term project should address an interesting and perhaps controversial issue in climate science, and be of order 10–20 pages in length. Students were asked to summarize their project in a 10-minute presentation to the class toward the end of the semester. Each student selects a topic for the project. For example, they could address the validity of the following controversial statements that are often found in popular literature:
