Portland Community College | Portland, Oregon

The purpose of this course is to develop an understanding of Earth's climate system and climate change, including historical perspectives.

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

Earth and space sciences are based on observations, measurements and samples collected in the field. Field-based learning is recommended by numerous professional Geology organizations, including the American Geological Institute and the National Association of Geoscience Teachers. Field-based learning improves both metacognition and spatial/visualization abilities while helping to transfer basic concepts to long-term memory by engaging multiple senses at the same time. Spatial thinking is critical to success in STEM (Science, Technology, Engineering, and Math) disciplines. Field work may include:

• Å·ÖÞ±­¾öÈü¾º²Âapp_Å·ÖÞ±­×ãÇòÍø-Ͷע|¹ÙÍøing skills in site characterization
• Application of key terms and concepts
• Measurement and data collection
• Interpretation of data and observations, and fitting them to a larger context

Field work may be physically challenging and may require overland travel on foot or other means to field sites, carrying equipment and supplies, and making measurements in unusual or awkward positions for a length of time.  Field work may include inherent risks (uneven terrain, variable weather, insects, environmental irritants, travel stress, etc.). Field work can be adapted to individual abilities.

Regarding the teaching of basic scientific principles (such as geologic time and the theory of evolution), the Portland Community College Geology/General Science Subject Area Committee  stands by the following statements about what is science.
 

• 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.

• “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).

• Geology/General Science 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.

• 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.

Upon successful completion of the course students should be able to:

1. Explain past, present, and future global climate patterns using an Earth system perspective that includes the atmosphere, hydrosphere, solid earth, and biosphere.
2. Identify both human and non-human forcings on the climate system and the system's 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. Assess the risks posed by climate change, to themselves and society, and evaluate the efficacy of possible responses using scientifically valid methods of inquiry.   

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

The material in this course will be presented in a lecture/discussion format accompanied by laboratory exercises. Other educationally sound methods may be employed such as guest lectures, field trips, research papers, presentations and small group work. 

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.
