Climate Science

Program Offerings

Offering type
Minor

Climate science is math, physics, chemistry, biology and computer sciences, applied together to understand how Earth's climate works, how it has changed in the past and how it will change in the future. Whether students are interested in policymaking, sustainability, natural hazards, city planning, pollution, geoengineering, natural resources, energy or conservation, a broad and accurate understanding of climate science is required.  The minor in climate science is offered by the Department of Geosciences.

Goals for Student Learning

The primary goal of the climate science (CS) minor is to provide fundamental climate literacy to students who may not have completed the sequence of math, physics, chemistry, biology and computer science prerequisites for the geoscience major. The goal is to develop a rigorous and accessible curriculum that allows any Princeton student to learn the climate science they need in order to pursue climate science–facing careers and make informed decisions as citizens on a changing planet.

Prerequisites

There are no prerequisites for the minor. However, some 300-level and above advanced elective courses have their own prerequisites.

Admission to the Program

Students must declare the minor by April 01 of their junior year. Before declaring, students should get their planned coursework approved by the director of minors (DoM) [a member of the undergraduate work committee (UWC), chaired by the director of undergraduate studies (DUS)].

Program of Study

Students start with 3–4 core classes. These core courses are taught every year and represent a comprehensive climate science curriculum designed to be accessible to non-STEM majors.

After finishing 3–4 courses in the core curriculum, students choose 1–2 capstone electives. These capstone electives are designed to build on knowledge gained from the core courses and focus deeper attention on specific aspects of climate science. For students who have completed the prerequisites, there also is a collection of climate-related advanced electives that they can substitute for core or capstone courses with permission of the DoM.

In practice, only GEO courses are accepted for the minor, so there are no relevant restrictions on double-counting courses with the student’s major. A geosciences major is not permitted to minor in climate science.

No other, non-credit-bearing work is required.

Courses

GEO 102A - Climate: Past, Present, and Future (also ENV 102A/STC 102A) Not offered this year SEN

Which human activities are changing our climate, and does climate change constitute a major problem? We will investigate these questions through an introduction to climate processes and an exploration of climate from the distant past to today. We will also consider the impact of former and ongoing climate changes on the global environment and on humanity. Finally, we will draw on climate science to identify and evaluate possible courses of action. Intended to be accessible to students not concentrating in science or engineering. Two 80-minute lectures per week. D. Sigman

Two lectures, one three-hour laboratory. B. Schoene

GEO 202 - Ocean, Atmosphere, and Climate (also ENV 326) Spring SEN

The ocean and the atmosphere control Earth's climate, and in turn climate and atmospheric changes influence the ocean. We explore the circulation of the ocean and atmosphere, their chemical compositions and their interactions that make up the climate system, including exchanges of heat and carbon. We then investigate how these circulations control marine ecosystems and the biological and chemical cycles of the Earth system. The final part of the course focuses on human impacts, including changes in coastal environments and acidification and warming that result from increased atmospheric carbon dioxide. One weekly precept complements lectures. B. Ward

GEO 203 - The Habitable Planet (also ENE 203) Fall QCR

We discuss how these processes create and sustain habitable conditions on Earth's surface, including feedbacks and tipping points as recorded in the geologic record. Topics include: stellar and planetary formation, plate tectonics, the geologic record, natural resources, the hydrologic cycle and sedimentation, paleoclimatology, and the "Anthropocene". Students will apply these topics to the recent geologic past to assess the impact of humans on their environments. E. Niespolo
