Topic 6 Atmosphere and Climate Change
In this section we support learning in Topic 6: Atmosphere and Climate Change.
The four subtopics include an introduction to the atmosphere and the greenhouse effect, causes and impacts of climate change, including a climate justice lens, climate change mitigation and adaptation, and the role and depletion of stratospheric ozone.
6.1 Introduction to the Atmosphere
This subtopic provides an introduction to the atmosphere and at SL, covers the basics of the greenhouse effect. At HL, we need to understand the structure of the atmosphere, the evolution of this in geological...
6.2 Climate Change - Causes and Impacts
We will explore the evidence for climate change and the impacts on ecosystems and human societies along with the use of diagrams and models to demonstrate possible feedback loops. Perspectives on climate...
6.3 Climate Change - Mitigation and Adaptation
Global action is required to avoid the risk of catastrophic climate change. Decarbonisation and carbon neutrality are considered as part of the range of mitigation strategies available. Adaptation strategies...
6.4 Stratospheric Ozone
At SL this subtopic considers the role of stratospheric ozone in protecting the biosphere from UV radiation and how ODSs destroy ozone molecules. The Montreal Protocol is evaluated as the reason why the...
