Kelly Wanser: Emergency medicine for our climate fever

The video discusses unintentional climate experiments by humans, focusing on sulfur emissions from ships and their cooling effect on clouds. It explores marine cloud brightening and volcanic phenomena as potential climate interventions. Current research and experiments are highlighted, along with the challenges and solutions in implementing these interventions. The video emphasizes the need for urgent action and collaboration to address climate change effectively.

What is the primary benefit of reducing sulfur emissions from ships?

• It decreases greenhouse gases.

• It improves human health.

• It reduces ocean pollution.

• It increases cloud formation.

How do brighter clouds affect the climate?

• They reflect more sunlight back to space.

• They increase greenhouse gas emissions.

• They absorb more sunlight.

• They trap more heat.

What is the main goal of the marine cloud brightening project?

• To decrease the number of hurricanes.

• To enhance coral reef growth.

• To increase the reflectivity of ocean clouds.

• To reduce sulfur emissions from ships.

What natural event inspired the idea of stratospheric aerosol injection?

• Hurricane formation

• Volcanic eruptions

• Tornadoes

• Forest fires

What is a potential risk of dispersing particles into the stratosphere?

• Increased volcanic activity

• Decreased ocean temperatures

• Damage to the ozone layer

• Increased greenhouse gas emissions

What is the purpose of the Harvard scope axe experiment?

• To develop new cloud formation techniques

• To release large amounts of sulfur into the atmosphere

• To study the effects of greenhouse gases

• To study the chemistry and physics of small particles in the stratosphere

What is a major challenge in understanding climate interventions?

• Insufficient technology for experiments

• Complexity of the Earth's climate system

• Lack of public awareness

• Lack of interest from scientists

What is the predicted consequence if climate change is not addressed urgently?

• Decrease in global sea levels

• Devastating impacts on natural systems and human life

• Stabilization of global temperatures

• Increased agricultural productivity

What historical agreement successfully addressed an environmental threat?

• Rio Declaration

• Montreal Protocol

• Paris Agreement

• Kyoto Protocol

What is a moral hazard associated with researching climate interventions?

• It may encourage increased emissions.

• It could lead to economic instability.

• It might delay efforts to reduce emissions.

• It could cause political conflicts.
