Climate and Climate Change
There will be two weekly quizzes which will be based on the reading assignments for the week and material from previous lectures. The quizzes will be posted on the web right after class (generally on Mondays and Wednesdays) and you will have 24 hours to turn them in. They will have 3-5 short questions to which you will have to give short answers (one word or sentence, sometimes a short paragraph). You are required to turn in at least 10 quizzes out of a total of 19. If you turn in more than 10 quizzes the additional ones will be counted as extra credit. The quizzes will be graded on a 0-5-10 scale: 10 for turning in the quiz with an obvious effort to answer the questions, 5 for turning it in late, 0 for not turning it in (any quizzes turned in more than 72 hours after posting will get a 0). It should take you no longer than 5-10 minutes to fill in the quizzes. The quizzes will be posted on the web using WebQ all you need is access to a computer with a browser (Netscape or Explorer) and have your UW NetID and password handy. Click on the corresponding dates below to answer the quiz. At the end of each quiz you will have the option of asking us a question on the class material (was something not clear in the previous lecture? did you have a question about the reading assignment? are you curious about something?).

Extra
Credit
There will be a number of extra credit
opportunities during the course of the quarter. Some will be in the form
of extra credit questions on quizzes, homework assignments and exams, others
will be based on attending a seminar related to "Climate and Climate Change",
and writing a short paragraph describing what the seminar was about.
You can get up to 20 points for each seminar you attend (with a maximum
of 2 seminars that you will get extra credit for). I will be posting
below the dates of some seminars you might find interesting.

Reader's Guide to the Text
Chapter 1 - Global ChangeIntroduces all the topics covered in the course. Accurately reflects the content and level of difficulty of the course. It will be useful to reread this chapter when studying for the final. The Summary, Key Terms, Review Problems and Critical Thinking Problems at the end of this and all chapters will help you assess what you've learned. We've incorporated some of this material into the assignments and exams.
Chapter 2 - Daisyworld:
An introduction to Systems
An introduction to systems
and feedbacks. This chapter is, in some ways, the most difficult in the
book, because it's about concepts. Learning the graphing conventions in
Figs. 2-1 and 2-2 is optional: some students find it helpful: others don't.
The important thing is to grasp the idea behind the figures and be able
to express it in a way that makes sense to you. You can skip the section
"Response of Equilibrium States to Forcing".
Chapter 3 - Global
Energy Balance: The Greenhouse Effect
Don't worry about the frequency
of radiation or about photons and photon energy. There are two equations
in this chapter that you'll be required to learn and apply in simple problems:
the inverse square law (p. 38) and the Stefan Boltzmann Law (p. 41). The
planetary energy balance (p. 41-42) is fundamental material that we'll
come back to again and again in the course. The same is true of the section
on the greenhouse effect. You can just skim the section entitled "Physical
Causes of the Greenhouse Effect", which gets a bit too deeply involved
in the physics of radiation, but being able to understand the diagram Fig.
3-13 is really important.
Note that colored figures like Fig. 3-3 are repeated in the center section of the book.
Chapter 4 - The
Atmospheric Circulation System
This chapter is not as well
written the other chapters in the book so we've supplemented it with lecture
notes that can be accessed by clicking on the appropriate dates in the
lecture schedule. The figures (many of which are repeated in the center
section of the book) are helpful and informative.
Skip the subsections entitled "The Movement of Air" and "The General Circulation" and the box entitled "The Relationship among Temperature...". All you'll need to know about this material is in the lecture notes. The intermediate section "The Driving Force, The Global Energy Distribution, which contains Figs 4.3 and 4.4 is important. The section "The Coriolis Force" is well written but difficult. In class we'll simply describe what the Coriolis force does, but we won't try to explain why it does what it does. Read carefully the sections entitled "The Distribution of Surface Winds","Seasonal Variability", and "Global Distributions of Temperature and Rainfall."
Chapters 5, 6 -
The Circulation of the Oceans & Circulation of the Solid Earth
You won't need to learn
this material in detail but these chapters are well worth skimming. Most
of the discussion of the ocean circulation (p. 82-88) is too difficult.
A knowledge of the basic concepts of plate tectonics (Chapter 6 p. 106-116;
) will enhance your appreciation of the material on climatic variations
on the 100-million year time scale, covered later in the book.
Chapter 7 - Recycling
of the Elements: The Carbon Cycle
The textbook co-author,
James Kasting, is one of the leading authorities on the carbon cycle. This
chapter contains fundamental material that needs to be read carefully.
Figs. 7-7 and 7-12 are too detailed: we'll present simpler versions in
class. You can skip the box on the pH scale and the chemical equations
on p. 146. Try the review questions at the end of the Chapter.
Chapter 8 - Long-Term
Climate Regulation
Outlines the origin and
history of the earth and its atmosphere. The first of a series of five
chapters dealing with the history of climate. Contains mostly factual material
that can be read and assimilated much more quickly than the conceptual
ideas about geochemical cycles presented in Chapter 7. The material on
the formation of the solar system is optional. No need to memorize the
terms in Fig. 8-11.
Chapter 9 - The
Chemical Environment: Evolution of the Atmosphere
This Chapter on the history
of the atmosphere focuses on oxygen and ozone in the earth's atmosphere
and their connection with life. It is concerned with the timing of the
rise of oxygen and the development of the ozone layer which protects life
on earth from the harmful effects of the sun's ultraviolet radiation. Much
of the discussion is concerned with the evidence concerning the history
of oxygen levels in the atmosphere and with the mechanisms believed to
have played a role in controlling it. Not all the questions raised at the
beginning of the chapter have been answered. The reading assignment is
designed summarize what we know and how we know it and to give students
some appreciation for the remaining controversies. Much of the chapter
can be skimmed lightly or skipped without losing the main ideas.
Read "Key Questions", "Chapter Overview", "Introduction", The "Prebiotic Atmosphere". It's OK to skip "The Origin of Life" and "Effect of Life on the Early Atmosphere". Skim "The Rise of Oxygen: Geological Evidence" just to get Read "The Rise of Ozone" carefully. Fig. 9-12 is important. Skim "Possible Causes of the Rise of Oxygen" taking note of the final conclusion. Read "Modern Controls on atmospheric O2: Forest Fires and Atmospheric Oxygen", but it's OK to skip the remainder of this section.
Chapter 10 - Biodiversity
through Earth History
The title of this chapter
is a bit misleading. Most of it is about climate and earth history of the
past 100-million years. Read from p. 201: "The Cretacious-Tertiary Mass
Extinction" onward. To check your comprehension, try Review Questions 4
and 5.
Chapter 11 - Pleiostene
Glaciations
Here the focus shifts to
the climate of the past few million years, a period dominated by large
swings between ice ages and warmer 'interglacials'. Read the entire chapter.
Try Review Questions 1-5, Critical Thinking Problem 2b.
Chapter 12 - Short-Term
Climate Variability
This final chapter on climate
history focuses on the past 20,000 years and traces the recovery from the
most recent ice age and ends with a discussion of El Nino and other kinds
of short term climate fluctuations. Try Review Questions 1, 3, 4, 5, and
6.
Chapter 13 - Global
Warming
This chapter on the global
warming closely parallels the treatment in class. It contains some highly
informative graphs on future projections of carbon dioxide concentrations.
Chapter 14 - Ozone
Depletion
This chapter on the ozone
hole closely parallels the treatment in class.
