Course Description

Covers characteristics of Earth's climate system. Includes the atmosphere, ocean, biosphere, and solid Earth as well as past, present, and future climate change and future mitigation and adaptation efforts. Includes a weekly lab. Audit available.

Addendum to Course Description

The purpose of this course is to develop an understanding of Earth's climate system and climate change, including historical perspectives. It is a one-term survey course that may be included as part of the year’s sequence in physical science for college transfer credit.
 

The course will have as many of the following components as feasible: lectures, discussions, lab activities, videos, CD’s, slides, live television and computer reports, and computer-aided instruction. It is necessary to successfully complete the lab part of the course in order to pass the course.
 

The text and materials for this course have been chosen by the faculty and viewpoints shall be that of the author(s). This includes the topics of relativity, the geologic time scale, evolution of the Earth and its atmosphere, the solar system, the galaxy and the universe.
 

Regarding the teaching of basic geologic principles (such as geologic time and the theory of evolution), the Portland Community College Geology Department stands by the following statements about what is science.
 

  1. Science is a fundamentally non-dogmatic and self-correcting investigatory process. A scientific theory is neither a guess, dogma, nor myth. The theories developed through scientific investigation are not decided in advance, but can be and often are modified and revised through observation and experimentation.

  2. “Creation science,” also known as scientific creationism, is not considered a legitimate science, but a form of religious advocacy. This position is established by legal precedence (Webster v. New Lenox School District #122, 917 F.2d 1004).

  3. Geology instructors at Portland Community College will teach the generally accepted basic geologic principles (such as geologic time and the theory of evolution) not as absolute truth, but as the most widely accepted explanation for our observations of the world around us. Instructors will not teach that “creation science” is anything other than pseudoscience.

  4. Because "creation science", "scientific creationism", and "intelligent design" are essentially religious doctrines that are at odds with open scientific inquiry, the Geology/General Sciences SAC at Portland Community College stands with such organizations such as the National Association of Geoscience Teachers, the American Geophysical Union, the Geological Society of America, and the American Geological Institute in excluding these doctrines from our science curriculum.


Students are expected to be able to read and comprehend college-level science texts and perform basic mathematical operations to successfully complete this course

Intended Outcomes for the course

After taking this course, students should be able to:

1. Use an Earth system perspective that includes the atmosphere, hydrosphere, solid earth, and biosphere to explain past, present, and future global climate patterns.

2. Identify both human and non-human forcings on the climate system and the system response to these forcings including possible feedback mechanisms.  

3. Use real data to document climate change impacts both globally and in the Pacific Northwest and link these changes to the current scientific understanding of climate change.

4. Make field, laboratory and web based observations and measurements of climate, use scientific reasoning to interpret these observations and measurements, and compare the results with current models of the climate system identifying areas of congruence and discrepancy.

5. Access climate science information from a variety of sources, evaluate the quality of this information, and critically compare this information with current models of the climate system.

6. Use scientifically valid modes of inquiry, individually and collaboratively, to critically assess the hazards and risks posed by climate change, to themselves and society, and evaluate the efficacy of ethically robust responses to these risks.

7. Communicate effectively about Earth’s changing climate, its impacts, and possible responses from an Earth System perspective.

Quantitative Reasoning

Students completing an associate degree at Portland Community College will be able to analyze questions or problems that impact the community and/or environment using quantitative information.

Aspirational Goals

After taking this course, students should be able to:

  1. Engage in informed reflection about their personal role in Earth’s climate system and make evidence-based decisions on how to react to future climate change.

  2. Become a Climate science literate citizen.

    A Climate-science-literate citizen:

  • understands the essential principles of Earth’s climate system

  • knows how to assess scientifically credible information about climate

  • communicates about climate and climate change in a meaningful way

  • is able to make informed and responsible decisions with regard to actions that may affect climate

Course Activities and Design

The laboratory is not separate from the lecture, but will usually be correlated in such a way as to reinforce the materials being discussed in the lecture section. It is necessary for the student to successfully complete the laboratory section of the course in order to earn a grade in the course. Math will be used to solve ratio, percentage, and simple algebraic problems.  Also included are the design, reading, and interpreting of graphs.

Outcome Assessment Strategies

The instructor will choose from the following methods of assessment: exams, quizzes, lab exercises, written reports, oral presentations, group projects, class participation, homework assignments, and field trips. The instructor shall detail the methods to be used to the students at the beginning of the course.
