Core 2.1 Causes of Global Climate Change
How natural and human processes affect the global energy balance
Embedded Files
IB Learning Outcomes:
- The atmospheric system, including the natural greenhouse effect and energy balance (incoming shortwave radiation and outgoing longwave radiation)
Changes in the global energy balance, and the role of feedback loops, resulting from:
- solar radiation variations, including global dimming due to volcanic eruptions
- terrestrial albedo changes and feedback loops
- methane gas release and feedback loops
The enhanced greenhouse effect and international variations in greenhouse gas sources and emissions, in relation to economic development, globalization and trade
Questions:
- 1: What is the atmosphere of the earth?
- 2. What is the importance of a) clouds and b) carbon dioxide in the energy balance of the earth?
- 3. Why is it warmer in summer than winter?
- 4. What is the greenhouse effect?
- 5. What is Global Climate Change?
- 6. What is the difference between GE and GCC?
Questions:
In groups and without using your computer. You will be given paper to draw annotated diagrams explaining the following:
- 1 Describe how heat is transferred from the tropics towards the poles
- 2. Using an annotated diagram only:
- Illustrate the variations in temperature and pressure with altitude in the atmosphere.
- Explain what happens to incoming solar radiation as it passes through the earth’s atmosphere.
Feedback Loops Activity
Feedback Loops Activity
Vocabulary:
Vocabulary:
A Negative feedback loop means a return or stable equilibrium (Stable)
A positive feedback loop means a change away from equilibrium (Unstable)
Exercise
Exercise
- Read this Guardian article
- Read Nagle and Cooke p. 431-2
- Watch the following videos
In groups, create 3 diagrams explaining the feedback loops of the following. Make sure to use proper vocabulary.

Global Climate Change
Global Climate Change
In groups of 2, answer the Activity 3, # 1, 2, 3 questions in Nagle and Cook p. 434-5
Then, write a thesis statement for the following IB style questions:
- "The causes of global climate change are human." Discuss this statement
- Suggest how globalization is linked to the enhanced greenhouse effect.
- "HICs are responsible for mitigating the causes of global climate change." Discuss this statement
Remember, a good thesis statement:
- tells the reader how you will interpret the significance of the subject matter under discussion.
- is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.
- directly answers the question asked of you. A thesis is an interpretation of a question or subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel.
- makes a claim that others might dispute.
- is usually a single sentence somewhere in your first paragraph that presents your argument to the reader. The rest of the paper, the body of the essay, gathers and organizes evidence that will persuade the reader of the logic of your interpretation.
- Every word of your essay should is nome way relate to your thesis statement
