Course ID: | GEOG 4040/6040. 3 hours. |
Course Title: | Global Environmental Change Past and Present |
Course Description: | Chronology and geomorphic, isotopic, and palynological evidence of Quaternary paleoclimates. The effects of past climatic changes upon present landscapes, historic short-term fluctuations in temperature and precipitation, and possible explanations for climatic change are emphasized. |
Oasis Title: | Global Env Chg Past Present |
Semester Course Offered: | Offered fall semester every year. |
Grading System: | A-F (Traditional) |
|
Course Objectives: | Successful completion of this course will provide the following learning outcomes:
A basic understanding of the physical processes that operate in the
earth/ocean/atmosphere system and how these affect regional variations in
climate/environment
An awareness of the changing nature of the earth's climate across a range of time
scales and an understanding that in today’s climate we see only a snapshot of Earth
history
An understanding of the scientific methods that have been used to collect and analyze
data on climate/environmental change and its impact on humanity
A greater understanding of the importance of science in understanding the everyday
functioning of our planet, and its crucial role in policy decision-making in view of
global warming issues
An understanding that because the earth’s landscapes are complex, being the products
of processes that have varied with changing climate, they provide evidence of past
conditions
The realization that changes in global climate can have dire consequences for humans
as they can induce droughts that are difficulty to cope with
A understanding that climate is forever changing and that we must be prepared for it
The understanding that past changes in climate are a way of assessing human
influences on climate today
The realization that climate change can be abrupt and not slow as previously thought
The ability to think critically by assessing information on climate change in the
past in relation to what is happening today
The realization that the earth is fragile and constantly changing in ways we do not
yet fully understand
This course meets the following General Education Abilities by accomplishing the
specific learning objectives listed below:
Communicate effectively through writing. This is met by a series of writing
assignments associated with supplemental reading and data analysis.
Communicate effectively through speech. This is met by oral presentations,
discussion leading, and classroom participation.
Computer Literacy is addressed through course administration, student-faculty
electronic interaction, and data analysis activities and assignments.
Critical Thinking is central to the learning objectives of this class, and is
developed through homework assignments, lecture, classroom discussion, and inquiry-
based learning efforts.
Moral Reasoning (Ethics) is an important element of this course, as it explores
linkages among physical environment, climatic variability, human activities, and
past/future global environmental change. Moral reasoning is developed through
lectures, writing assignments, classroom discussion, and inquiry-based learning
activities. |
