How Geoengineering Can Help Fight Global Warming

The video addresses climate change denial and explores geoengineering as a potential solution. It discusses natural climate episodes like the 1991 Mount Pinatubo eruption and presents geoengineering techniques such as artificial volcanoes and ocean fertilization. The video highlights ethical and governance issues, including the risks of unilateral geoengineering actions by rogue nations. It also emphasizes the challenges in achieving global climate agreements and the need for further research to understand the potential consequences of geoengineering.

• The eruption of Mount Etna

• The eruption of Mount Vesuvius

• The eruption of Mount Pinatubo

• The eruption of Mount St. Helens

Which of the following is a proposed method of geoengineering to reduce global warming?

• Planting more trees

• Using solar panels

• Dispersing particles in the atmosphere

• Building wind turbines

What is a major ethical concern regarding geoengineering?

• The need for more scientific research

• The lack of technological advancement

• The potential for a single nation to act unilaterally

• The cost of implementation

What is a significant challenge in achieving global climate agreements?

• Technological limitations

• Lack of scientific evidence

• Political disagreements among nations

• Insufficient funding

Why is it important to conduct research on geoengineering now?

• To increase public awareness

• To understand the potential unintended consequences
