The video discusses the long-standing awareness of climate change, highlighting the acceleration of CO2 emissions and the rapid melting of Arctic ice. It proposes solutions like renewable energy and conservation but also introduces geo-engineering as a potential quick fix. The speaker emphasizes the challenges and moral hazards of geo-engineering, urging for serious debate and research. The video concludes with a call for international cooperation and consideration of future scenarios.

What is the significance of the 1953 New York Times article mentioned in the introduction?

• It was the first article to discuss climate change.

• It shows that awareness of climate change is not a recent development.

• It proposed the Kyoto Protocol.

• It was written by a Nobel laureate.

What does the speaker highlight about the current state of CO2 emissions?

• They are accelerating faster than previous worst-case scenarios.

• They have stabilized over the past decade.

• They are decreasing due to global efforts.

• They are growing at a slower rate than expected.

What is the primary method of geo-engineering discussed in the video?

• Reducing industrial emissions.

• Planting more trees.

• Using sulfuric acid particles to reflect sunlight.

• Increasing renewable energy usage.

What historical event does the speaker compare geo-engineering to?

• The signing of the Paris Agreement.

• The discovery of the ozone hole.

• The eruption of Mount Pinatubo.

• The Industrial Revolution.

How does the speaker suggest geo-engineering could be improved?

• By combining it with increased fossil fuel usage.

• By increasing the amount of sulfur used.

• By using photophoretic forces to levitate particles.

• By deploying geo-engineering only in urban areas.

What is the speaker's stance on the cost of geo-engineering?

• It is prohibitively expensive.

• It is more expensive than reducing emissions.

• It is relatively cheap compared to other solutions.

• It is not discussed in the video.

What is a potential risk of relying on geo-engineering according to the speaker?

• It could cause more volcanic eruptions.

• It might increase the cost of renewable energy.

• It could lead to increased global temperatures.

• It might reduce the urgency to cut emissions.

Why does the speaker believe geo-engineering should be discussed openly?

• To encourage more countries to adopt it.

• To replace current climate policies.

• To increase funding for fossil fuels.

• To prepare for future decisions regarding its use.

What does the speaker suggest is necessary for managing geo-engineering?

• Complete reliance on geo-engineering.

• Increased fossil fuel consumption.

• A global treaty to decide its use.

• More private sector involvement.

What is the moral hazard associated with geo-engineering?

• It might increase global temperatures.

• It could cause more natural disasters.

• It might make climate impacts seem less severe.

• It could lead to increased emissions.
