The lesson begins by examining the concept of 'unnatural disasters.' Students will explore how climate change has shifted the baseline for extreme weather events, making them more frequent, intense, and unpredictable. Using evidence from the transcript, we will discuss how the 1.5-degree guardrail has been breached, leading to phenomena such as fires in Los Angeles during winter, the southward migration of cyclones (like Cyclone Alfred), and the breaking of flood records by meters. We will define 'pyro-convective storms'—fires that create their own weather systems—and discuss why traditional firefighting methods are becoming ineffective against these new extremes.
Government agencies and scientific organizations in Australia provide data on long-term weather trends and disaster resilience.
This topic challenges the conventional wisdom of 'Net Zero' by introducing the concept of 'Real Zero.' Students will learn why some experts view Net Zero as relying on 'accounting tricks' and offsets rather than genuine emissions reductions. We will analyze the example of Fortescue Metals' target to eliminate fossil fuels entirely from their iron ore production by 2030. The discussion will cover the economic transition, the rapid growth of renewable energy (solar and wind) in Australia, and the critique of continuing to export fossil fuels while greening domestic electricity grids.
Independent climate bodies and industry councils track Australia's progress toward renewable energy targets and emission reductions.
The final topic delves into the controversial science of geoengineering, specifically solar radiation management. Framed as a 'medical amputation' analogy from the transcript, students will explore why this high-risk, cheap, and fast-acting solution (such as injecting sulphur into the stratosphere) is being considered as global temperatures rise. We will discuss the potential geopolitical conflicts, the risks of altering global weather patterns (monsoons, droughts), and the 'science deficit' surrounding these technologies compared to safer, slower methods like forest regeneration and carbon drawdown.
Scientific academies and government departments assess the potential risks and governance required for climate intervention technologies.
