The video explores the concept of solar geoengineering, inspired by volcanic eruptions like Mount Pinatubo, which cooled global temperatures. It discusses the potential of using aerosols and other methods to reflect sunlight and combat climate change. While some scientists support this approach, citing the need for innovative solutions, others warn of risks like termination shock and governance challenges. The debate includes ethical concerns and the impact on decarbonization efforts. The video highlights the importance of research and global cooperation in addressing these complex issues.

What was the impact of the Mount Pinatubo eruption on global temperatures?

• It caused temperatures to rise by half a degree Celsius.

• It had no significant impact on global temperatures.

• It caused temperatures to drop by about half a degree Celsius.

• It caused temperatures to drop by two degrees Celsius.

Which of the following is a method of solar geoengineering?

• Planting more trees

• Injecting aerosols into the stratosphere

• Reducing carbon emissions

• Increasing fossil fuel usage

What is a major concern about solar geoengineering?

• It might cause unpredictable changes in climate systems.

• It has no effect on global temperatures.

• It could lead to a decrease in global cooperation.

• It is too expensive to implement.

What is 'termination shock' in the context of solar geoengineering?

• A sudden cooling of the planet

• A rapid warming if solar geoengineering is abruptly stopped

• A decrease in global cooperation

• An increase in fossil fuel usage

Why did Sweden reject a solar geoengineering project in 2021?

• It was not technologically feasible

• Because of potential geopolitical tensions
