Climate Change: The Science and Impact
This lesson explores the mechanism of climate change, distinguishing between natural processes and human-induced warming, while examining the global consequences and the 'Albedo effect'.
Learning objectives
- Identify the difference between the natural greenhouse effect and the enhanced greenhouse effect.
- Explain the human and physical causes of contemporary climate change.
- Evaluate the social, economic, and environmental impacts of rising global temperatures.

Key vocabulary
- Climate Change
- The long-term shift in average weather patterns and temperatures.
- Fossil Fuels
- Natural fuels such as coal or gas, formed in the geological past from the remains of living organisms.
- Greenhouse Gases
- Gases in the atmosphere that trap heat, such as Carbon Dioxide and Methane.
- Deforestation
- The process of clearing a wide area of trees, reducing the planet's ability to absorb CO2.
- Albedo Effect
- The proportion of light or radiation that is reflected by a surface, typically that of a planet or ice.
Core worksheet (first questions)
- Explain the difference between the greenhouse effect and the enhanced greenhouse effect.
- Identify three greenhouse gases and a human source for each.
- Describe how the atmosphere traps heat using the terms 'short-wave' and 'long-wave' radiation.
- How does the melting of ice contribute to rising sea levels?
